목록 은 대부분 다른 텍스트처럼 작동하지만, 알아야 할 목록과 관련된 몇 가지 CSS 속성과 고려해야 할 모범 사례가 있습니다. 이 기사는 모든 것을 설명합니다.

간단한 목록 예제

전제조건:	Basic computer literacy, HTML basics (study Introduction to HTML), CSS basics (study Introduction to CSS), CSS text and font fundamentals.
목적:	목록 스타일과 관련된 모범 사례 및 속성에 익숙해지기.

우선, 간단한 목록 예제를 봅시다. 이 기사 전체에서 우리는 순서가 없는, 순서가 있는, 설명 목록을 살펴볼 것입니다 — 모두 유사한 스타일링 기능이 있으며, 일부 유형은 목록 유형과 다릅니다. 스타일이 지정되지 않은 예제는 Github 에서 가능 합니다 (소스 코드 도 확인하십시오.)

If you go to the live example now and investigate the list elements using browser developer tools, you'll notice a couple of styling defaults:

Handling list spacing

When styling lists, you need to adjust their styles so they keep the same vertical spacing as their surrounding elements (such as paragraphs and images; sometimes called vertical rhythm), and the same horizontal spacing as each other (you can see the finished styled example on Github, and find the source code too.)

List-specific styles

Now we've looked at general spacing techniques for lists, let's explore some list-specific properties. There are three properties you should know about to start with, which can be set on {{htmlelement("ul")}} or {{htmlelement("ol")}} elements:

Bullet styles

As mentioned above, the {{cssxref("list-style-type")}} property allows you to set what type of bullet to use for the bullet points. In our example, we've set the ordered list to use uppercase roman numerals, with:

You can find a lot more options by checking out the {{cssxref("list-style-type")}} reference page.

Bullet position

The {{cssxref("list-style-position")}} property sets whether the bullets appear inside the list items, or outside them before the start of each item. The default value is outside, which causes the bullets to sit outside the list items, as seen above.

Using a custom bullet image

The {{cssxref("list-style-image")}} property allows you to use a custom image for your bullet. The syntax is pretty simple:

However, this property is a bit limited in terms of controlling the position, size, etc. of the bullets. You are better off using the {{cssxref("background")}} family of properties, which you'll learn a lot more about in the Styling boxes module. For now, here's a taster!

In our finished example, we have styled the unordered list like so (on top of what you've already seen above):

list-style shorthand

The three properties mentioned above can all be set using a single shorthand property, {{cssxref("list-style")}}. For example, the following CSS:

The values can be listed in any order, and you can use one, two or all three (the default values used for the properties that are not included are disc, none, and outside). If both a type and an image are specified, the type is used as a fallback if the image can't be loaded for some reason.

Controlling list counting

Sometimes you might want to count differently on an ordered list — e.g. starting from a number other than 1, or counting backwards, or counting in steps of more than 1. HTML and CSS have some tools to help you here.

start

The {{htmlattrxref("start","ol")}} attribute allows you to start the list counting from a number other than 1. The following example:

reversed

The {{htmlattrxref("reversed","ol")}} attribute will start the list counting down instead of up. The following example:

value

The {{htmlattrxref("value","ol")}} attribute allows you to set your list items to specific numerical values. The following example:

Active learning: Styling a nested list

In this active learning session, we want you to take what you've learned above and have a go at styling a nested list. We've provided you with the HTML, and we want you to:

If you make a mistake, you can always reset it using the Reset button. If you get really stuck, press the Show solution button to see a potential answer.

Playable code

<div class="body-wrapper" style="font-family: 'Open Sans Light',Helvetica,Arial,sans-serif;">
  <h2>HTML Input</h2>

  <li>Next, open the box.</li>
  <li>Finally, place the three magic items in the box, in this exact order, to complete the spell:
    <ol>
      <li>The book of spells</li>
