Introduction

A few months ago, I saw VS Code released an update that had Emmet abbreviations built in. At the time, I saw a demo and it looked like an interesting tool but I knew very little about it. This past week, while practicing css and scaffolding a blog-like web page for practice I decided to give Emmet a try. After reading some of the documentation and trying it out, within five minutes I was able to replicate what I had done manually with one line of “code”. The entire process is described below.

What We’ll Build

Displayed below is the scaffold of the webpage I built. As it can be seen, in the body element there is a nav element and four div elements that will contain our articles and their metadata.

How We’ll Build It

The hmtl above can be programatically built using the abbreviation below.

1

html>(head>title+link)+(body>(nav>ul>li.nav-item*3)+(div>div.article>h2.article-title+h6.article-date+p.article-description)*4



To break down some of the things that are going on here, we can start with the syntax. The > character denotes that the item on the left is the parent of the item(s) on the right. Similarly, the + character is used to describe siblings. Similar to math operations, parentheses evaluate what’s inside them. Elements themselves can contain additional data such as class names and ids. This data can be appended to the element name just like css with . for classes and # for ids.

With that knowledge, we can see that we have an html root element with head and body children. The head element has a title and link child elements. The body element has a nav element with a ul child which contains three li elements. The nav element has a div sibling which contains four div children that serve as the containers for our articles and their metadata.

Adding some style

To help visualize what the page looks like we can add some css .

After linking our css with the webpage as well as adding some content to the page, the result will look as follows.
