HTML Classes: HTML class attribute is used to specify a single (or) multiple class names for HTML element. And the class name can be used by CSS and JavaScript to do some tasks in HTML.
HTML Classes
A class attribute can be defined with <style> tag or by using a separate file (.) character. In HTML we can use the same class for selecting elements.
Example 1:
<!DOCTYPE html>
<html>
<head>
<style>
.headings{
color: lightgreen;
font-family: cursive;
background-color: black; }
</style>
</head>
<body>
<h1 class="headings">This is first heading</h1>
<h2 class="headings">This is Second heading</h2>
<h3 class="headings">This is third heading</h3>
<h4 class="headings">This is fourth heading</h4>
</body>
</html>
Example 2:
<style>
.fruit {
background-color: orange;
color: white;
padding: 10px;
}
</style>
<h2 class="fruit">Mango</h2>
<p>Mango is king of all fruits.</p>
<h2 class="fruit">Orange</h2>
<p>Oranges are full of Vitamin C.</p>
<h2 class="fruit">Apple</h2>
<p>An apple a day, keeps the Doctor away.</p>
HTML Multiple Classes
We can use multiple class names with HTML elements. These class names must be separated by a space.
Example:
<!DOCTYPE html>
<html>
<style>
.fruit {
background-color: orange;
color: white;
padding: 10px;
}
.center {
text-align: center;
}
</style>
<body>
<h2>Multiple Classes</h2>
<p>All three elements have the class name "fruit". In addition, Mango also have the class name "center", which center-aligns the text.</p>
<h2 class="fruit center">Mango</h2>
<h2 class="fruit">Orange</h2>
<h2 class="fruit">Apple</h2>
</body>
</html>
