HTML elements are used to represent and show computer code on a web page. These features aid in the preservation of the code's layout and style for improved readability. Here are some important HTML code elements:
1. <code> Element:
The <code> element specifies a piece of computer code. It is usually used within the context of a sentence or paragraph.
<p>This is an example of inline <code>code</code>.</p>
2. <pre> Element:
The element <pre> (preformatted) is used to keep both spaces and line breaks within the enclosing content. It is widely used to display code blocks.
<pre>
<code>
// This is an example of a code block
function example() {
console.log("Hello, World!");
}
</code>
</pre>
3. <kbd> Element:
The <kbd> (keyboard input) element represents user input, such as keyboard input or user-entered text.
<p>To save a file, press <kbd>Ctrl + S</kbd>.</p>
4. <samp> Element:
The <samp> (sample output) element is used to contain program or computing system output.
<p>The output of the program is <samp>Hello, World!</samp></p>
5. <var> Element:
In computer programming, the <var> (variable) element is used to express the name of a variable.
<p>The value of the variable <var>x</var> is 42.</p>
6. <span> Element with class="code" :
Developers will sometimes employ a <span> element with a specified class (e.g., 'class="code") to style inline code that has no semantic significance.
<p>This is an example of inline <span class="code">code</span>.</p>
These elements aid in the structure and formatting of HTML code, making it more legible and creating a clear visual separation between conventional text and code. CSS styling can also be applied to these elements to improve the appearance of the code on the web page.
