There are a number of methods that you can use to lay out your web pages and applications. MDN contains a number of in-depth guides to the different methods, and this page provides an overview of them all.

Flexbox

CSS Flexible Box Layout, commonly known as flexbox, is a layout model optimized for user interface design, and the layout of items in one dimension. In the flex layout model, the children of a flex container can be laid out in any direction, and can "flex" their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent.
