-<p>These tips are based upon common knowledge and experimentation.</p>
-<p>An optimized web page not only provides for a more responsive site for your visitors, but also reduces the load on your web servers and Internet connection. This can be crucial for high volume sites or sites which have a spike in traffic due to unusual circumstances such as breaking news stories.</p>
-<p>Optimizing page load performance is not just for content which will be viewed by narrow band dialup or mobile device visitors. It is just as important for broadband content and can lead to dramatic improvements even for your visitors with the fastest connections.</p>
-<h2 id="Tips" name="Tips">Tips</h2>
-<h3 id="Reduce_page_weight" name="Reduce_page_weight">Reduce page weight</h3>
-<p>Page weight is by far the most important factor in page-load performance.</p>
-<p>Reducing page weight through the elimination of unnecessary whitespace and comments, commonly known as minimization, and by moving inline script and CSS into external files, can improve download performance with minimal need for other changes in the page structure.</p>
-<p>Tools such as <a class="external" href="http://tidy.sourceforge.net/">HTML Tidy</a> can automatically strip leading whitespace and extra blank lines from valid HTML source. Other tools can "compress" JavaScript by reformatting the source or by obfuscating the source and replacing long indentifiers with shorter versions.</p>
-<h3 id="Minimize_the_number_of_files" name="Minimize_the_number_of_files">Minimize the number of files</h3>
-<p>Reducing the number of files referenced in a web page lowers the number of <a href="/en-US/docs/HTTP" title="en-US/docs/HTTP">HTTP</a> connections required to download a page.</p>
-<p>Depending on a browser's cache settings, it may send an <code>If-Modified-Since</code> request to the web server for each CSS, JavaScript or image file, asking whether the file has been modified since the last time it was downloaded.</p>
-<p>By reducing the number of files that are referenced within a web page, you reduce the time required for these requests to be sent, and for their responses to be received.</p>
-<p>If you use background images a lot in your css, you can reduce the amount of HTTP look-ups needed by combining the images into one, known as an image sprite. Then you just apply the same image each time you need it for a background, and adjust the x/y coordinates appropriately. This technique works best with elements that will have limited dimensions, and will not work for every use of a background image. However the fewer http requests and single image caching can help reduce pageload time.</p>
-<p>Too much time spent querying the last-modified time of referenced files can delay the initial display of a web page, since the browser must check the modification time for each CSS or JavaScript file, before rendering the page.</p>
-<h3 id="Reduce_domain_lookups" name="Reduce_domain_lookups">Reduce domain lookups</h3>
-<p>Since each separate domain costs time in a DNS lookup, page-load time will grow along with the number of separate domains appearing in CSS link(s) and JavaScript and image src(es).</p>
-<p>This may not always be practical; however, you should always take care to use only the minimum necessary number of different domains in your pages.</p>
-<h3 id="Cache_reused_content" name="Cache_reused_content">Cache reused content</h3>
-<p>Make sure that any content that can be cached, is cached, and with appropriate expiration times.</p>
-<p>In particular, pay attention to the <code>Last-Modified</code> header. It allows for efficient page caching; by means of this header, information is conveyed to the user agent about the file it wants to load, such as when it was last modified. Most web servers automatically append the <code>Last-Modified</code> header to static pages (e.g. <code>.html</code>, <code>.css</code>), based on the last-modified date stored in the file system. With dynamic pages (e.g. <code>.php</code>, <code>.aspx</code>), this, of course, can't be done, and the header is not sent.</p>
-<p>So, in particular for pages which are generated dynamically, a little research on this subject is beneficial. It can be somewhat involved, but it will save a lot in page requests on pages which would normally not be cacheable.</p>

-<h3 id="Optimally_order_the_components_of_the_page" name="Optimally_order_the_components_of_the_page">Optimally order the components of the page</h3>
-<p>Download page content first, along with any CSS or JavaScript that may be required for its initial display, so that the user gets the quickest apparent response during page-loading. This content is typically text, and can therefore benefit from text compression in transit, thus providing an even quicker response to the user.</p>
-<p>Any dynamic features that require the page to complete loading before being used, should be initially disabled, and then only enabled after the page has loaded. This will cause the JavaScript to be loaded after the page contents, which will improve the overall appearance of the page load.</p>
-<h3 id="Reduce_the_number_of_inline_scripts" name="Reduce_the_number_of_inline_scripts">Reduce the number of inline scripts</h3>
-<p>Inline scripts can be expensive for page loading, since the parser must assume that an inline script could modify the page structure while parsing is in progress. Reducing the use of inline scripts in general, and reducing the use of <code>document.write()</code> to output content in particular, can improve overall page loading. Use modern <a href="/en-US/docs/AJAX" title="en-US/docs/AJAX">AJAX</a> methods to manipulate page content for modern browsers, rather than the older approaches based on <code>document.write()</code>.</p>
-<h3 id="Use_modern_CSS_and_valid_markup" name="Use_modern_CSS_and_valid_markup">Use modern CSS and valid markup</h3>
-<p>Use of modern CSS reduces the amount of markup, can reduce the need for (spacer) images, in terms of layout, and can very often replace images of stylized text -- that "cost" much more than the equivalent text-and-CSS.</p>
-<p>Using valid markup has other advantages. First, browsers will have no need to perform error-correction when parsing the HTML. ((This is aside from the philosophical issue of whether to allow format variation in user input, and then programmatically "correct" or normalize it; or whether, instead, to enforce a strict, no-tolerance input format)).</p>
-<p>Moreover, valid markup allows for the free use of other tools which can <em>pre-process</em> your web pages. For example, <a class="external" href="http://tidy.sourceforge.net/">HTML Tidy</a> can remove whitespace and optional ending tags; however, it will refuse to run on a page with serious markup errors.</p>
-<h3 id="Chunk_your_content" name="Chunk_your_content">Chunk your content</h3>
-<p>Tables for layouts are a legacy method that should not be used any more. Layouts utilizing {{ HTMLElement("div") }} blocks, and in the near future, <a href="/en-US/docs/CSS/Using_CSS_multi-column_layouts" title="en-US/docs/CSS3_Columns">CSS3 Multi-column Layout</a> or <a href="/en-US/docs/Using_flexbox" title="en-US/docs/Using_flexbox">CSS3 Flexible Box Layout</a>, should be used instead.</p>
-<p>Tables are still considered valid markup, but should be used for displaying tabular data. To help the browser render your page quicker, you should avoid nesting your tables.</p>
-<p>Rather than deeply nesting tables as in:</p>
-<pre>&lt;TABLE&gt;
-  &lt;TABLE&gt;
-    &lt;TABLE&gt;
-          ...
-    &lt;/TABLE&gt;
-  &lt;/TABLE&gt;
-&lt;/TABLE&gt;</pre>
-<p>use non-nested tables or divs as in</p>
-<pre>&lt;TABLE&gt;...&lt;/TABLE&gt;
-&lt;TABLE&gt;...&lt;/TABLE&gt;
-&lt;TABLE&gt;...&lt;/TABLE&gt;
-</pre>
-<p>See also: <a class="external" href="http://www.w3.org/TR/css3-multicol/" title="http://www.w3.org/TR/css3-multicol/">CSS3 Multi-column Layout Spec</a> and <a class="external" href="http://www.w3.org/TR/css3-flexbox/" title="http://www.w3.org/TR/css3-flexbox/">CSS3 Flexible Box Layout</a></p>
-<h3 id="Specify_sizes_for_images_and_tables" name="Specify_sizes_for_images_and_tables">Specify sizes for images and tables</h3>
-<p>If the browser can immediately determine the height and/or width of your images and tables, it will be able to display a web page without having to reflow the content. This not only speeds the display of the page but prevents annoying changes in a page's layout when the page completes loading. For this reason, <code>height</code> and <code>width</code> should be specified for images, whenever possible.</p>
-<p>Tables should use the CSS selector:property combination:</p>
-<pre>  table-layout: fixed;
-</pre>
-<p>and should specify widths of columns using the <code>COL</code> and <code>COLGROUP</code> html tags.</p>
-<h3 id="Choose_your_user-agent_requirements_wisely" name="Choose_your_user-agent_requirements_wisely">Choose your user-agent requirements wisely</h3>
-<p>To achieve the greatest improvements in page design, make sure that reasonable user-agent requirements are specified for projects. Do not require your content to appear pixel-perfect in all browsers, especially not in down-version browsers.</p>
-<p>Ideally, your basic minimum requirements should be based on the consideration of modern browsers that support the relevant standards. This can include: Firefox 3.6+ on any platform, Internet Explorer 8.0+ on Windows, Opera 10+ on Windows, and Safari 4 on Mac OS X.</p>
-<p>Note, however, that many of the tips listed in this article are common-sense techniques which apply to any user agent, and can be applied to any web page, regardless of browser-support requirements.</p>
-<h2 id="Example_page_structure" name="Example_page_structure">Example page structure</h2>

-    <dl>
-      <dd>

-        JavaScript files for functions <strong>required</strong> during the loading of the page, but not any DHTML that can only run after page loads.</dd>

-</dl>
-<dl>
-  <dd>
-    <dl>
-      <dd>
-        · <code>SCRIPT </code>...<br>
-        Any scripts which will be used to perform DHTML. DHTML script typically can only run after the page has completely loaded and all necessary objects have been initialized. There is no need to load these scripts before the page content. That only slows down the initial appearance of the page load.</dd>
-      <dd>
-        Minimize the number of files for performance while keeping unrelated JavaScript in separate files for maintenance.</dd>
-      <dd>
-        If any images are used for rollover effects, you should preload them here after the page content has downloaded.</dd>
-    </dl>
-  </dd>
-</dl>
-<h2 id="Example_page_structure" name="Example_page_structure">Use async and defer, if possible</h2>
-<p>Make the javascript scripts such that they are compatible with both the <a href="https://developer.mozilla.org/en-US/docs/HTML/Element/script#Attributes" title="https://developer.mozilla.org/en-US/docs/HTML/Element/script">async</a> and the <a href="https://developer.mozilla.org/en-US/docs/HTML/Element/script#Attributes" title="https://developer.mozilla.org/en-US/docs/HTML/Element/script">defer</a> and use <a href="https://developer.mozilla.org/en-US/docs/HTML/Element/script#Attributes" title="https://developer.mozilla.org/en-US/docs/HTML/Element/script">async</a> whenever possible, specially if you have multiple script tags.<br>
-  With that, the page can stop rendering while javascript is still loading. Otherwise the browser will not render anything that is after the script tags that do not have these atributes.</p>
-<p>Note: Even though these attibutes do help a lot for the first time a page is loaded, you should use them but not rely that it will work in all browsers. If you follow all guidelines to make good javascript code, there is no need to change your code.</p>

-<p><strong>Note:</strong> Vector images are the ultimate responsive images because the files are small while the images are scalable to any size without loss of definition. <a href="https://developer.mozilla.org/en-US/Learn/HTML/Howto/Add_vector_image_to_a_webpage">Use vector images</a> whenever you can; they're even more effective than the techniques described here. This article demonstrates how to use multiple versions of a bitmap image, in different sizes, to provide the best possible output given the current screen size and resolution.</p>
-
-<p>Note also that while this article discusses how to implement responsive images in HTML, <a href="http://blog.cloudfour.com/responsive-images-101-part-8-css-images/">sometimes it makes more sense to use CSS</a>.</p>

-<h2 id="Why_responsive_images">Why responsive images?</h2>
-
-<p>Here's the problem we're solving:</p>
-
-<p>On a webpage, you have a box that must be filled by an image. More precisely, the box must be filled by pixels, so many wide by so many tall. Just how many pixels wide and tall depends on your visitor's device.</p>
-
-<p>You also have an image file, a set number of pixels wide and a set number of pixels tall. The image naturally should display in a box the same number of pixels wide and tall as the image. If the box is significantly too big, the image doesn't have enough pixels and it's going to look grainy. If the box is significantly too small, you're wasting bandwidth and slowing down your page by loading a larger image than you need.</p>
-
-<p><em>Responsive images </em>solves this problem by letting you offer the browser several image files, all showing the same thing but containing different numbers of pixels. That way the browser can load an image that will look sharp enough but won't needlessly slow down the page.</p>
-
-<h2 id="So_how_do_you_do_it">So how do you do it?</h2>
-
-<p>In this section, we'll solve what is, by far, the most common problem: displaying identical image content, just larger or smaller depending on the device. In the next section, we'll look at some less common scenarios.</p>
-
-<p>Remember the {{htmlelement("img")}} element? It lets you point the browser to a single source file:</p>
-
-<pre class="brush: html">&lt;img src="chalet.jpg" alt="Quaint wooden cottage in the Alps"&gt;</pre>
-
-<p>We can use two new attributes, {{htmlattrxref("srcset", "img")}} and {{htmlattrxref("sizes", "img")}} <code>sizes</code> (<strong>in addition to</strong> {{htmlattrxref("alt", "img")}} and {{htmlattrxref("src", "img")}}), to provide several additional source images and enough information to help the browser pick the right one. It looks like this when you're done:</p>
-
-<pre class="brush: html">&lt;img
-    src="chalet.jpg"
-    alt="Quaint wooden cottage in the Alps"
-    srcset="
-        chalet-256.jpg 256w,
-        chalet-512.jpg 512w,
-        chalet-1024.jpg 1024w"
-    sizes="
-        (max-width: 500px) 100vw,
-        (max-width: 900px) 40vw,
-        400px"&gt;
-</pre>
-
-<p><code>srcset</code> and <code>sizes</code> each contain comma-separated lists.</p>
-
-<p><strong>For <code>srcset</code>: </strong>Between the commas, write</p>
-
-<ol>
- <li>an <strong>image filename</strong> (<code>chalet-256.jpg</code>)</li>
- <li>a space</li>
- <li>the image's <strong>inherent width in pixels</strong> (<code>256w</code>)</li>
-</ol>
-
-<p><strong>For <code>sizes</code>: </strong>Between the commas, write</p>
-
-<ol>
- <li>a <strong>media condition</strong> (<code>(max-width:500px)</code>)</li>
- <li>a space</li>
- <li>the <strong>width of the slot</strong> the image will fill when the media condition is true (<code>100vw</code>)</li>
-</ol>
-
-<div class="note">
-<ul>
- <li>For the slot width, you may provide an absolute length (<code>px</code>, <code>em</code>) or a relative length (<code>vw</code>, that is, percent of viewport width). You may also provide a combination using {{cssxref("calc")}}.</li>
- <li>The last slot width is the default (for when no media condition is true). Therefore, the last slot width has <strong>no</strong> media condition.</li>
- <li><code>max-width</code> simply means, "if the user's screen is no wider than X pixels".</li>
- <li>The browser ignores everything after the first matching condition. Pay attention to the order of the media conditions.</li>
-</ul>
-</div>
-
-<div class="note">
-<p><strong>Why can't the browser just look at the CSS to find out the width of the image slot? </strong></p>
-
-<p>Because the browser's preloader starts downloading images before the main parser has a chance to interpret CSS and JavaScript. You want that, because images are heavy and circumventing the preloader may add another 20% on to your page load time.</p>

-
-<h3 id="Images_at_different_resolutions_but_one_real-world_size">Images at different resolutions but one real-world size</h3>
-
-<p>If you're supporting multiple display densities, but everyone sees your image at the same real-world size, you should use <code>srcset</code> with x-descriptors and without <code>sizes</code>:</p>
-
-<pre class="brush: html">&lt;img
-    src="chalet.jpg"
-    alt="Quaint wooden cottage in the Alps"
-    srcset="chalet.jpg,
-        chalet-1-5x.jpg 1.5x,
-        chalet-2x.jpg 2x,
-        chalet-3x.jpg 3x"&gt;
-</pre>
-
-<div class="note">
-<ul>
- <li>
-  <p>Note that <code>1x</code> is implied.</p>
- </li>
- <li>
-  <p><code>x</code> means, "this many device pixels for one CSS pixel"</p>
- </li>
-</ul>
-</div>
-
-<h3 id="Art_direction">Art direction</h3>
-
-<p><strong>Art direction</strong> means cropping an image either 1) to make the main subject easier to see when the image is small or 2) to make a landscape image suitable for a portrait slot (and vice versa). (However, it must be the same image content in all cases. To, say, show phone users a jet and desktop users a ladybug is a misuse of the responsive image mechanism.)<br>
- Art direction is a more complex problem, and needs a more complex solution: the {{htmlelement("picture")}} element. <code>&lt;picture&gt;</code> is a wrapper containing several {{htmlelement("source")}} elements, followed by the all-important {{htmlelement("img")}} element:</p>
-
-<pre class="brush: html">&lt;picture&gt;
-    &lt;source
-        media="(min-width: 1000px)"
-        srcset="chalet-desktop.jpg"&gt;
-    &lt;source
-        media="(min-width: 700px)"
-        srcset="chalet-tablet.jpg"&gt;
-    &lt;img src="chalet-phone.jpg" alt="Quaint wooden cottage in the Alps"&gt;
-&lt;/picture&gt;
-</pre>
-
-<ul>
- <li>Just like <code>&lt;img&gt;</code>, <code>&lt;source&gt;</code> can take <code>srcset</code> and <code>sizes</code>. In a responsive images scenario, do not use <code>&lt;source&gt;</code> and <code>src</code> together.</li>
- <li><code>&lt;source&gt;</code> may also take a <code>media</code> attribute containing a CSS <a href="https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Media_queries">media query</a>. Use <code>media</code> only in an art direction scenario, because it leaves the browser no choice of which image to use. When you do use <code>media</code>, don't offer media conditions within <code>sizes</code>.</li>
- <li><strong>In all cases, you must provide an <code>&lt;img&gt;</code> element, with <code>src</code> and <code>alt</code>, right before <code>&lt;/picture&gt;</code>, otherwise no images will appear.</strong></li>
-</ul>
-
-<h3 id="Use_modern_image_formats_boldly">Use modern image formats boldly</h3>
-
-<p>There are several exciting new image formats (think WebP and JPEG-2000) that can maintain a low file size and high quality at the same time. However, browser support is spotty.</p>
-
-<p><code>&lt;picture&gt;</code> lets us continue catering to older browsers. Supply MIME types inside <code>type</code> attributes so the browser can immediately reject unsupported file types:</p>
-
-<pre class="brush: html">&lt;picture&gt;
-  &lt;source type="image/svg+xml" srcset="pyramid.svg"&gt;
-  &lt;source type="image/webp" srcset="pyramid.webp"&gt;
-  &lt;img src="pyramid.png" alt="regular pyramid built from four equilateral triangles"&gt;
-&lt;/picture&gt;
-</pre>
-
-<ul>
- <li>Do <em>not </em>use the <code>media</code> attribute, unless you also need art direction.</li>
- <li>In a <code>&lt;source&gt;</code> element, you can only refer to images of the type declared in <code>type</code>.</li>
- <li>As before, you're welcome to use comma-separated lists with <code>srcset</code> and <code>sizes</code>, as needed.</li>
-</ul>
