Using flexbox to vertically and horizontally center content is usually the preferred method. All it takes is three lines of code in the container element to set
display: flex and then center the child element vertically and horizontally using
align-items: center and
justify-content: center respectively. You can view the Flexbox centering snippet for the code and examples.
Using the grid module is very similar to flexbox and also a common technique, especially if you are already using grid in your layout. The only difference from the previous technique is the
display which is set to
grid instead. You can view the Grid centering snippet for the code and examples.
Transform centering uses, as the name implies, CSS transforms to center an element. It depends on the container element having a
position: relative, allowing the child element to utilize
position: absolute to position itself. Then
left: 50% and
top: 50% are used to offset the child element and
transform: translate(-50%, -50%) to negate its position. You can view the Transform centering snippet for the code and examples.
Last but not least, table centering is an older technique which you might favor when working with older browsers. It depends on the use of
display: table in the container element. This allows the child element to use
display: table-cell in combination with
text-align: center and
vertical-align: middle to center itself horizontally and vertically. You can view the Display table centering snippet for the code and examples.
