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.
Utilities for layout
For faster mobile-friendly and responsive development, CoreUI for Bootstrap includes dozens of utility classes for showing, hiding, aligning, and spacing content.
Use our display utilities for responsively toggling common values of the
display property. Mix it with our grid system, content, or components to show or hide them across specific viewports.
CoreUI for Bootstrap is built with flexbox, but not every element’s
display has been changed to
display: flex as this would add many unnecessary overrides and unexpectedly change key browser behaviors. Most of our components are built with flexbox enabled.
Should you need to add
display: flex to an element, do so with
.d-flex or one of the responsive variants (e.g.,
.d-sm-flex). You’ll need this class or
display value to allow the use of our extra flexbox utilities for sizing, alignment, spacing, and more.
Margin and padding
padding spacing utilities to control how elements and components are spaced and sized. CoreUI for Bootstrap includes a six-level scale for spacing utilities, based on a
1rem value default
$spacer variable. Choose values for all viewports (e.g.,
margin-right: 1rem in LTR), or pick responsive variants to target specific viewports (e.g.,
margin-right: 1rem —in LTR— starting at the
display isn’t needed, you can toggle the
visibility of an element with our visibility utilities. Invisible elements will still affect the layout of the page, but are visually hidden from visitors.
