+<p>The <code>Storage</code> interface of the Web Storage API provides access to a particular domain's session or local storage. It allows, for example, the addition, modification, or deletion of stored data items.</p>
+
+<p>To manipulate, for instance, the session storage for a domain, a call to the {{domxref("Window.sessionStorage")}} is made; whereas for local storage the call is made to {{domxref("Window.localStorage")}}.</p>

+ <dd>When passed a key name and value, will add that key to the storage, or update that key's value if it already exists.</dd>

+
+<p>Here we access a <code>Storage</code> object by calling <code>localStorage</code>. We first test whether the local storage contains data items using <code>!localStorage.getItem('bgcolor')</code>. If it does, we run a function called <code>setStyles()</code> that grabs the data items using {{domxref("Storage.getItem()")}} and uses those values to update page styles. If it doesn't, we run another function, <code>populateStorage()</code>, which uses {{domxref("Storage.setItem()")}} to set the item values, then runs <code>setStyles()</code>.</p>

+<pre class="brush: js">if(!localStorage.getItem('bgcolor')) {
+  populateStorage();
+}
+setStyles();
+
+function populateStorage() {
+  localStorage.setItem('bgcolor', document.getElementById('bgcolor').value);
+  localStorage.setItem('font', document.getElementById('font').value);
+  localStorage.setItem('image', document.getElementById('image').value);
+}
+
+function setStyles() {
+  var currentColor = localStorage.getItem('bgcolor');
+  var currentFont = localStorage.getItem('font');
+  var currentImage = localStorage.getItem('image');
+
+  document.getElementById('bgcolor').value = currentColor;
+  document.getElementById('font').value = currentFont;
+  document.getElementById('image').value = currentImage;
+
+  htmlElem.style.backgroundColor = '#' + currentColor;
+  pElem.style.fontFamily = currentFont;
+  imgElem.setAttribute('src', currentImage);
