What are CSScurrentColor and its practical applications?
Jun 20, 2025 am 12:48 AMcurrentColor is a dynamic keyword in CSS that references the current element text color, and its value will be automatically updated as the color attribute changes. Use currentColor to avoid repeatedly defining color values, keep borders, icons, shadows and other styles consistent with text colors. For example, after setting border-color: currentColor, just change the color to synchronize the border color. Application scenarios include icon color following text color, border and text color, and unified color matching of form focus status, etc. The method of using is simple, such as .box { color: green; border: 1px solid currentColor; }. Tips include using fill="currentColor" in the SVG icon and custom properties with CSS. Note: Modern browsers are widely supported, but you need to pay attention to compatibility issues in IE9 and below. It is recommended to explicitly set the color value to avoid uncertainty caused by inheritance. At the same time, check the actual rendering effect through DevTools and test the performance under different themes.
currentColor
is a very practical but often overlooked keyword in CSS. It is essentially a dynamic reference pointing to color
attribute value of the current element. That is, no matter what text color you set to the element in the style, currentColor
will "remember" that color and can be used for other CSS properties, such as borders, background colors, shadows, etc.
This is especially useful when creating consistent theme styles or developing component libraries, as it allows you to reuse color definitions without having to repeat specific values.
When to use currentColor
?
The most common thing is when you want a style (such as borders, icon colors) to be consistent with the text color, but don't want to write a dead color value.
For example: If you want to make a button, the text is blue and the border is blue; if you change the theme, it turns into green text and green border. At this time, if you write border-color: #3366cc
directly, you have to change two points every time you change the theme. But if you write border-color: currentColor
, you only need to change the text color once, and the border color will automatically change.
Application scenarios include but are not limited to:
- Icon color follows text color
- Borders, underscores and text in the same color
- The focus status of form control is uniform
How to use it in a project?
It's easy to use, just like using any color value:
.box { color: green; border: 1px solid currentColor; }
The above code will make the border color of .box
always equal to its text color. Even if you change the text color later through JavaScript or parent inheritance, the border will be automatically updated.
Some practical tips:
Use
fill="currentColor"
in SVG icons to change the color of the icon with the text color.It is more flexible to use with CSS custom properties, for example:
:root { --text-color: blue; } .example { color: var(--text-color); border-color: currentColor; }
Notes and compatibility
Although modern browsers basically support
currentColor
, it may not be recognized in some older versions (such as IE9 and below). If you need to be compatible with these old browsers, you may need to downgrade or avoid using them.In addition, one thing to note is that
currentColor
is not a fixed value, it is dynamic and depends oncolor
value of the current element. So if you don't setcolor
, it may inherit from the parent element, sometimes resulting in unexpected results.Tips:
- Always explicitly set
color
value to avoid uncertainty caused by inheritance - Use DevTools to see if the final rendered color is as expected
- Test performance under different topics for key UI components
Basically that's it.
currentColor
is not complicated, but it can help you reduce redundant code and improve maintainability, especially in designing systems and theme switching scenarios.The above is the detailed content of What are CSScurrentColor and its practical applications?.

Choosing the correct display value in CSS is crucial because it controls the behavior of elements in the layout. 1.inline: Make elements flow like text, without occupying a single line, and cannot directly set width and height, suitable for elements in text, such as; 2.block: Make elements exclusively occupy one line and occupy all width, can set width and height and inner and outer margins, suitable for structured elements, such as; 3.inline-block: has both block characteristics and inline layout, can set size but still display in the same line, suitable for horizontal layouts that require consistent spacing; 4.flex: Modern layout mode, suitable for containers, easy to achieve alignment and distribution through justify-content, align-items and other attributes, yes

In Vue, provide and inject are features for directly passing data across hierarchical components. The parent component provides data or methods through provide, and descendant components directly inject and use these data or methods through inject, without passing props layer by layer; 2. It is suitable for avoiding "propdrilling", such as passing global or shared data such as topics, user status, API services, etc.; 3. Note when using: non-responsive original values ??must be wrapped into responsive objects to achieve responsive updates, and should not be abused to avoid affecting maintainability.
