How to Create Classes using CSS ?
A class in CSS is a group of CSS property like font-style, height, width, color, etc. which is when used as an attribute in an HTML tag, the CSS styling is applied to that tag.
Syntax:
.class_name {
CSS attributes;
}A period character or symbol “.” is used which is followed by the class name. Then opening and a closing parenthesis “{ }” is given within which CSS styling is declared.
Explanation: <style/> tag is used to define CSS styling within a .HTML file. A period character “.” is used to declare a class which is followed by the class name which is “green-text” in our example. Then we give opening and closing parenthesis “{ }” within which we define CSS properties.
HTML
<style> .green-text { /* CSS properties*/ color: green; font-size:250%;} </style> |
Assigning our CSS class to an HTML tag:
Explanation: In the below implementation we have assigned our “green-text” CSS class to the </p> tag, which will apply our CSS styling to the contents of that </p> tag.
HTML
<!DOCTYPE html><html><head><style>/*CSS class*/.green-text { color: green; font-size:250%;}</style></head><body> <!-- class "green-text" is assigned to the </p> tag --><p class="green-text">Welcome to GeeksforGeeks</p></body></html> |
Output:
As you can see we have successfully created a class using CSS and assigned it to an HTML element. For further knowledge about CSS, selectors go through this article.
