Using Border in CSS

Defining border in CSS

The CSS border property allows you to define a line border for an element:

h1 {
   border: 5px solid red;
}
a {
   border: 2px solid green; 
}

It is actually a shorthand for three CSS line border subproperties:

• border-width
• border-style
• border-color

Working with border: CSS syntax

To define a line border in CSS, follow the syntax example below:

border: width style color;

The available values will be explained in the following section.
