Introduction to CSS and Border Management

When designing websites, one of the challenges you may face is managing different styles for various sections of the page. CSS, or Cascading Style Sheets, is a tool that allows you to define your own styles for HTML elements. One of the important features of CSS is border management, which gives you the ability to control the color, thickness, and type of border lines.

Feature border-block-start-color

The feature border-block-start-color is one of the properties available in CSS that allows you to set the color of the starting block border. This feature works in right-to-left and left-to-right contexts, enabling you to apply styles with less code in a more efficient manner.

This feature is particularly useful when you want a design to be displayed correctly across different languages where the text direction varies. Working with this feature in designs that require a change in language direction can be very effective.

Using border-block-start-color

As a simple example, assume you want to set the border color above a block to red. You can accomplish this by using the following code:


.article {
border-block-start-color: red;
}

Code Explanation

.article: selector for the class that will be used to apply styles to elements with this class.
border-block-start-color: the property that determines the color of the top border of the block.
red: the color red, which will be assigned as the border color selected.
