CSS layout

At this point we've already looked at CSS fundamentals, how to style text, and how to style and manipulate the boxes that your content sits inside. Now it's time to look at how to place your boxes in the right place in relation to the viewport, and one another. We have covered the necessary prerequisites so can now dive deep into CSS layout, looking at different display settings, traditional layout methods involving float and positioning, and new fangled layout tools like flexbox.

CSS 레이아웃 소개

This article will recap some of the CSS layout features we've already touched upon in previous modules — such as different display values — and introduce some of the concepts we'll be covering throughout this module.

Floats 

Originally for floating images inside blocks of text, the float property has become one of the most commonly used tools for creating multiple column layouts on webpages. This article explains all.

Positioning

Positioning allows you to take elements out of the normal document layout flow, and make them behave differently, for example sitting on top of one another, or always remaining in the same place inside the browser viewport. This article explains the different position values, and how to use them.

Flexbox

A new technology, but with support now fairly widespread across browsers, Flexbox is starting to become ready for widespread use. Flexbox provides tools to allow rapid creation of complex, flexible layouts, and features that historically proved difficult with CSS. This articles explains all the fundamentals.

Advanced layout techniques

In our last article, we'll have a more detailed look at other CSS layout features, which are either simply not as well known or nascent and less cross-browser compatible. This includes CSS tables, CSS Grids, Multi-column layout, and others.

Assessments

The following assessments will test your ability to lay out web pages with CSS.

Creating a flexible multicolumn layout

This assessment tests your ability to create a standard multicolumn layout, with a few interesting features.

Creating a fixed control widget

This assessment challenges your understanding of positioning by asking you to create a fixed position control widget that allows the user to access a web app's controls regardless of where they scroll to.
