π Introduction
The border-block-start-color
property in CSS allows you to specify the color of the border on the block start side of an element. The block start side corresponds to the top edge in a left-to-right, top-to-bottom writing mode, but it can vary depending on the writing mode of the document (e.g., in a right-to-left writing mode, the block start side might be the right edge).
This property is useful for creating layouts that respect the documentβs writing direction.
π‘ Syntax
The syntax for the border-block-start-color
property is simple. It can be applied to any element that has borders, and the color can be specified using any valid CSS color value.
element {
border-block-start-color: color;
}
Here, color can be a named color, a hexadecimal value, an RGB value, an HSL value, or any other valid CSS color value.
ποΈ Default Value
The default value of the border-block-start-color
property is the current color of the element, which is determined by the color property of the element. If no specific value is set, it will inherit this color.
π Property Values
Value | Description |
---|---|
named-color | A color keyword, such as red, blue, green, etc. |
hexadecimal value | A hex code representing a color, such as #ff5733. |
RGB value | An RGB color value, such as rgb(255, 87, 51). |
HSL value | An HSL color value, such as hsl(9, 100%, 60%). |
transparent | Makes the border color fully transparent. |
currentcolor | Uses the current value of the color property. |
π Example
In this example, we'll change the color of the border on the block start side (top border in a standard left-to-right document) to green.

π₯οΈ Browser Compatibility
The border-block-start-color
property is supported in modern browsers, including Chrome, Firefox, Safari, Edge, and Opera. However, it's a good idea to test your design across different browsers to ensure consistent behavior.
π Conclusion
The border-block-start-color
property is a useful tool for customizing the appearance of borders in relation to the writing mode of your document. By setting the color of the border on the block start side, you can create visually appealing and contextually appropriate designs that work well with different languages and writing directions. Experiment with this property to enhance the visual style of your web layouts.
