HTML Lists
HTML provides different types of lists to organize content. This chapter will cover the three main types of lists: unordered lists, ordered lists, and definition lists. Each type of list has specific uses and unique formatting.
1. Unordered Lists
An unordered list is used to group a set of items in no particular order. It is created using the <ul> tag, with each list item defined by the <li> tag.
Example:
- Item 1
- Item 2
- Item 3
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>2. Ordered Lists
An ordered list is used to group a set of items in a specific order. It is created using the <ol> tag, with each list item defined by the <li> tag.
Example:
- First item
- Second item
- Third item
<ol>
<li>First item</li>
<li>Second item</li>
<li>Third item</li>
</ol>3. Definition Lists
A definition list is used to group terms and their definitions. It is created using the <dl> tag. Within a definition list, terms are defined by the <dt> tag, and each term’s description is defined by the <dd> tag.
Example:
- HTML
- Hypertext Markup Language
- CSS
- Cascading Style Sheets
<dl>
<dt>HTML</dt>
<dd>Hypertext Markup Language</dd>
<dt>CSS</dt>
<dd>Cascading Style Sheets</dd>
</dl>4. Nested Lists
You can create nested lists by placing a list inside another list item. This works with both ordered and unordered lists.
Example:
- Item 1
- Subitem 1.1
- Subitem 1.2
- Item 2
- Subitem 2.1
- Subitem 2.2
<ul>
<li>Item 1
<ul>
<li>Subitem 1.1</li>
<li>Subitem 1.2</li>
</ul>
</li>
<li>Item 2
<ul>
<li>Subitem 2.1</li>
<li>Subitem 2.2</li>
</ul>
</li>
</ul>5. Styling Lists
Lists can be styled using CSS to change their appearance. For example, you can change the list marker, add padding, or style the text.
Example:
- Styled Item 1
- Styled Item 2
- Styled Item 1
- Styled Item 2
<style>
.styled-list ul {
list-style-type: square;
padding-left: 20px;
}
.styled-list ol {
list-style-type: upper-roman;
padding-left: 20px;
}
</style>
<div class="styled-list">
<ul>
<li>Styled Item 1</li>
<li>Styled Item 2</li>
</ul>
<ol>
<li>Styled Item 1</li>
<li>Styled Item 2</li>
</ol>
