cu.css

Utilities

cu.css include a handful of utilities. Utilities help to solve common, yet specific problems found throughout a project. They can be used with any element in any context.

According to cube.fyi:

“A utility, in the context of CUBE CSS, is a CSS class that does one job and does that one job well.”

It’s important to note, cu.css doesn’t make use of any third-party tooling to generate utility classes. Instead, create any additional utilities by hand, as and when they are required.

The CSS for these utilities can be found in assets/scss/utilities.

Center #

The .center utility can be used to horizontally center block-level items.

Item centered
.center {
  display: flex;
  align-items: center;
  justify-content: center;
  flex-direction: column;
}

Text #

The .text-center utility class can be used to center the horizontal alignment of inline-level content inside a block element or table-cell box.

This text is horizontally centered 
.text-center {
  text-align: center;
}

Visually Hidden #

Use the .visually-hidden utility to visually hide an element in the browser while ensuring it’s still accessible to assistive technologies, such as screen readers.

/* 
VISUALLY HIDDEN

*/
.visually-hidden {
  border: 0;
  clip: rect(0 0 0 0);
  height: auto;
  margin: 0;
  overflow: hidden;
  padding: 0;
  position: absolute;
  width: 1px;
  white-space: nowrap;
}

This is different from using the [hidden] attribute which will hide the content from both the browser and assistive technologies.

Width #

The .w-full utility class can be used to make an element fill the full width of its parent container. Particularly useful for buttons and form elements.

.w-full {
  width: 100%;
}
