Ways to alter the color of the <div> Element based on its height or width?

My goal is to dynamically change the color of a div element based on its height.

Here's the criteria: If the div's height is less than or equal to 20%, I want it to be colored green. If it's above 20%, the color should be blue.

I'm looking to accomplish this using only CSS, if such a method exists.

Discover a unique technique for creating gradient background effects using the CSS properties background-size and repeat. By manipulating the size and repeat values, you can achieve different levels of coloration in your background.

For example, you can define specific color ranges based on height intervals. In this demonstration, orange is displayed for heights less than 100px, blue for heights between 100px and 200px, and red for heights exceeding 200px.

In the provided CSS snippet, the height of the element is manually set; however, it can be adjusted dynamically based on the content inside.

This technique can also be applied to control the width of the element, allowing for responsive coloration as the screen size changes.


Extend the gradient background effect to text coloration with the same method. By setting the text to have a transparent background, you can achieve colorful text effects based on the element's height.

Similarly, you can apply the technique to create colorful borders by utilizing multiple linear gradients for both the background and border-box, resulting in a visually appealing design.

Combine text coloration, background coloration, and border effects simultaneously for a comprehensive design, taking advantage of the unique gradient capabilities offered by CSS.


For a more interactive experience, experiment with controlling the coloration based on both the height and width of the element. You can resize the element to see how the gradients adjust dynamically.

Try the interactive demo below to explore the possibilities of creating customized gradient backgrounds using CSS properties like background-size and various linear gradients.
