Containers are a fundamental building block of CoreUI for React.js that contain, pad, and align your content within a given device or viewport.

How they work#

Containers are the most basic layout element in CoreUI for React.js and are required when using our default grid system. Containers are used to contain, pad, and (sometimes) center the content within them. While containers can be nested, most layouts do not require a nested container.

CoreUI for React.js comes with three different containers:

  • <CContainer>, which sets a max-width at each responsive breakpoint
  • <CContainer fluid>, which is width: 100% at all breakpoints
  • <CContainer {sm|md|lg|xl|xxl}>, which is width: 100% until the specified breakpoint

The table below illustrates how each container's max-width compares to the original <CContainer> and <CContainer fluid> across each breakpoint.

Extra small

Default container#

Our default <CContainer> class is a responsive, fixed-width container, meaning its max-width changes at each breakpoint.

Responsive containers#

Responsive containers allow you to specify a class that is 100% wide until the specified breakpoint is reached, after which we apply max-widths for each of the higher breakpoints. For example, <CContainer sm> is 100% wide to start until the sm breakpoint is reached, where it will scale up with md, lg, xl, and xxl.

<CContainer sm>100% wide until small breakpoint</CContainer>
<CContainer md>100% wide until medium breakpoint</CContainer>
<CContainer lg>100% wide until large breakpoint</CContainer>
<CContainer xl>100% wide until extra large breakpoint</CContainer>
<CContainer xxl>100% wide until extra extra large breakpoint</CContainer>

Fluid containers#

Use <CContainer fluid> for a full width container, spanning the entire width of the viewport.
