HTML Layout Elements

Websites often display content in multiple columns (like a magazine or newspaper).
HTML5 offers new semantic elements that define the different parts of a web page:

<header> - Defines a header for a document or a section
<nav> - Defines a container for navigation links
<section> - Defines a section in a document
<article> - Defines an independent self-contained article
<aside> - Defines content aside from the content (like a sidebar)
<footer> - Defines a footer for a document or a section
<details> - Defines additional details
<summary> - Defines a heading for the <details> element

HTML Layout Techniques

There are four different ways to create multicolumn layouts. Each way has its pros and cons:

HTML tables (not recommended)
CSS float property
CSS flexbox
CSS framework

Which One to Choose?

HTML Tables

The <table> element was not designed to be a layout tool! The purpose of the <table> element is to display tabular data. So, do not use tables for your page layout! They will bring a mess into your code. And imagine how hard it will be to redesign your site after a couple of months.

Note:Do NOT use tables for your page layout!

CSS Frameworks

If you want to create your layout fast, you can use a framework

CSS Floats

It is common to do entire web layouts using the CSS float property. Float is easy to learn - you just need to remember how the float and clear properties work. Disadvantages: Floating elements are tied to the document flow, which may harm the flexibility.

Float Example

CSS Flexbox

Flexbox is a new layout mode in CSS3.
Use of flexbox ensures that elements behave predictably when the page layout must accommodate different screen sizes and different display devices. Disadvantages: Does not work in IE10 and earlier.
