How to change the color of a Bootstrap list?

The color of the Bootstrap list can be specified by the class name, and the color can be set using the practical tool class that comes with Bootstrap, such as text-primary. If you need to overwrite the preset color, you can use CSS to directly overwrite the Bootstrap style, or add a custom class name and set the CSS style. More complex list color effects can be achieved through advanced CSS techniques such as pseudo-class selectors and media queries.

Bootstrap list changes color? This question seems simple, but it actually has a secret. Do you think it's so easy to just change the CSS attribute? Humph, I was so naive back then. In this post, I will take you deep into the Bootstrap list of dyeing art so you no longer scratch your ears and heads for color issues. After reading it, you will have a deeper understanding of the style mechanism of Bootstrap and the techniques of flexibly using CSS, and you can even learn from it and solve more style problems.

Let’s talk about the basics first. Bootstrap uses class names to control styles, you have to understand this. It's not as fancy as some frameworks, giving you a bunch of predefined color classes directly. You have to know that the list style of Bootstrap is actually mainly defined by <ul></ul> , <ol></ol> and <li> tags and their class names. If you want to change the color, the most direct way is to use the practical tools that come with Bootstrap.

For example, if you want the list item to turn blue, you can do this:

 <code class="html"><ul class="list-group"> <li class="list-group-item text-primary">Item 1</li> <li class="list-group-item text-primary">Item 2</li> <li class="list-group-item text-primary">Item 3</li> </ul></code>

text-primary is the blue style class provided by Bootstrap. You can search for other color classes, such as text-secondary , text-success , text-danger , etc. Simple and crude, but effective.

However, the colors preset by Bootstrap may not be enough, what should I do? At this time, you need to use your CSS skills. You can directly override the style of Bootstrap:

 <code class="css">.list-group-item { color: #FF69B4; /* Pink! */ }</code>

This code changes the text color of all list items to pink. Note that this method is relatively rough and will affect all list items. If you just want to change the color of a specific list item, you need more granular control. You can add a custom class name to the list item:

 <code class="html"><ul class="list-group"> <li class="list-group-item my-pink-item">Item 1</li> <li class="list-group-item">Item 2</li> <li class="list-group-item">Item 3</li> </ul> <style> .my-pink-item { color: #FF69B4; } </style></code>

In this way, only list items with my-pink-item class will turn pink. Remember, CSS priority is important, and you have to make sure your custom styles override Bootstrap's default styles.

This is just the tip of the iceberg. You can also use more advanced CSS techniques, such as pseudo-class selectors, media queries, etc. to achieve more complex list color effects. For example, you can change the color based on the status of the list item (such as mouse hover).

Finally, a small piece of advice: Don't rely too much on the styles that come with the framework. Only by learning to use CSS flexibly can you truly master the essence of the front-end. Remember, frameworks are just tools, and the ultimate control is still in your hands. Don't forget that the elegance of code is also an aesthetic.
