Support CoreUI Development
CoreUI is an MIT-licensed open source project and is completely free to use. However, the amount of effort needed to maintain and develop new features for the project is not sustainable without proper financial backing.
You can support our Open Source software development in the following ways:
- Buy the CoreUI PRO and get access to all PRO components, features, templates, and dedicated support.
- Hire Us! We create stunning designs, high-conversion landing pages, functional mobile apps and reliable web services – everything you need to offer your products or services online and always stay a tap away from your customers.
- Give us a star ⭐️ on Github.
Color & background
Set a background color with contrasting foreground color.
Overview
Added in v4.2.6Color and background helpers combine the power of our .text-*
utilities and .bg-*
utilities in one class. Using our Sass color-contrast()
function, we automatically determine a contrasting color
for a particular background-color
.
color-contrast
function, so we use our own via Sass. This means that customizing our theme colors via CSS variables may cause color contrast issues with these utilities.
<div class="text-bg-primary p-3">Primary with contrasting color</div>
<div class="text-bg-secondary p-3">Secondary with contrasting color</div>
<div class="text-bg-success p-3">Success with contrasting color</div>
<div class="text-bg-danger p-3">Danger with contrasting color</div>
<div class="text-bg-warning p-3">Warning with contrasting color</div>
<div class="text-bg-info p-3">Info with contrasting color</div>
<div class="text-bg-light p-3">Light with contrasting color</div>
<div class="text-bg-dark p-3">Dark with contrasting color</div>
With components
Use them in place of combined .text-*
and .bg-*
classes, like on badges:
<span class="badge text-bg-primary">Primary</span>
<span class="badge text-bg-info">Info</span>
Or on cards:
Some quick example text to build on the card title and make up the bulk of the card's content.
