In HTML, elements are categorized into two main types: block-level elements and inline elements. These categories define how elements are displayed and how they interact with other elements on the page.
- Block-Level Elements:
Block-level elements are those that typically create a block or box on the web page and occupy the full width of their parent container. They start on a new line and stack vertically by default. Some common block-level elements include:
<div>
: Used as a container for other elements or to group content.<p>
: Represents a paragraph of text.<h1>
to<h6>
: Heading elements that define different levels of headings.<ul>
: Represents an unordered list.<ol>
: Represents an ordered list.<li>
: Represents a list item.<table>
: Represents a table.<form>
: Represents a form for user input.
Example of block-level elements:
<div>
<h1>Heading</h1>
<p>This is a paragraph.</p>
<ul>
<li>List item 1</li>
<li>List item 2</li>
</ul>
</div>
- Inline Elements:
Inline elements are those that do not create a block or box on the web page. They do not start on a new line and only take up as much space as necessary. Inline elements can appear within text or alongside other elements. Some common inline elements include:
<span>
: Used for styling or grouping inline elements.<a>
: Represents a hyperlink.<strong>
: Represents strong emphasis or importance.<em>
: Represents emphasized text.<img>
: Represents an image.<input>
: Represents an input control.<button>
: Represents a clickable button.
Example of inline elements:
<p>This is a <span>span</span> of text with an <a href="#">inline link</a>.</p>
<p>Click <button>here</button> to submit the form.</p>
It’s important to note that the default behavior of elements can be modified using CSS. Block-level elements can be styled to behave as inline elements and vice versa by applying appropriate CSS properties such as display: inline
or display: block
.
Understanding the distinction between block-level and inline elements helps in structuring and styling HTML content effectively.
