You've probably not used CSS floats if you're just getting started with CSS. Although not one of the most used CSS properties, especially after the W3C introduced the CSS flex and grid, it's still worth knowing the CSS float property and how it works. To that effect, we decided to create this chapter about CSS floats.
However, it's good to mention that we won't delve deep into the CSS float property but will illustrate a few areas in which it remains quite useful.
If you come across legacy code that uses it, you will know what it is and how it works.
