Back in 2009, Sergey Chikuyonok wrote an article on how to present a new way of writing HTML and CSS code. This revolutionary plugin (called Zen Coding) has helped many developers through the years and has now reached a new level.

For those who prefer to watch instead of read, here is a summary of my favorite tricks.

How Does It Work?

Let’s face it: writing HTML code takes time, with all of those tags, attributes, quotes, braces, etc. Of course, most text editors have code completion, which helps a lot, but you still have to do a lot of typing. Emmet instantly expands simple abbreviations into complex code snippets.

HTML Abbreviations

Initializers

Getting started with a new HTML document takes less than a second now. Just type ! or html:5, hit “Tab,” and you’ll see an HTML5 doctype with a few tags to jumpstart your application.

• html:5 or ! for an HTML5 doctype
• html:xt for an XHTML transitional doctype
• html:4s for an HTML4 strict doctype

Easily Add Classes, IDs, Text and Attributes

Because Emmet’s syntax for describing elements is similar to CSS selectors, getting used to it is very easy. Try mixing an element’s name (e.g. p) with an identifier (e.g. p#description).

Also, you can combine classes and IDs. For example, p.bar#foo will output this:

Now let’s see how to define content and attributes for your HTML elements. Curly brackets are used for content. So, h1{foo} will produce this:

And square brackets are used for attributes. So, a[href=#] will generate this:

Nesting

By nesting abbreviations, you can build a whole page using just one line of code. First, the child operator, represented by >, allows you to nest elements. The sibling operator, represented by +, lets you place elements near each other, on the same level. Finally, the new climb-up operator, represented by ^, allows you to climb up one level in the tree.

Grouping

To effectively take advantage of nesting without turning them into a confusing mess of operators, you’ll need to group some pieces of code. It’s like math — you just need to use parentheses around certain pieces. For example, (.foo>h1)+(.bar>h2) will output this:

Implicit Tag Names

To declare a tag with a class, just type div.item, and then it will generate <div></div>.

In the past, you could omit the tag name for a div; so, you just had to type .item and it would generate <div></div>. Now Emmet is more intelligent. It looks at the parent tag name every time you expand the abbreviation with an implicit name. So, if you declare .item inside of a <ul>, it will generate <li></li> instead of <div></div>.

Here’s a list of all implicit tag names:

• li for ul and ol
• tr for table, tbody, thead and tfoot
• td for tr
• option for select and optgroup

Multiplication

You can define how many times an element should be outputted by using the * operator. So, ul>li*3 will produce:

Numbering

What about mixing the multiplication feature with some item numbering? Just place the $ operator in the element’s name, the attribute’s name or the attribute’s value to output the number of currently repeated elements. If you write ul>li.item$*3, it will output:

Why not try it right now? Go ahead: type in an Emmet HTML abbreviation, and hit the Tab key.

CSS Abbreviations

Values

Emmet is about more than just HTML elements. You can inject values directly into CSS abbreviations, too. Let’s say you want to define a width. Type w100, and it will generate:

Pixel is not the only unit available. Try running h10p+m5e, and it will output:

Here’s a list with a few aliases:

• p → %
• e → em
• x → ex

Extra Operator

You already know many intuitive abbreviations, such as @f, which produces:

Some properties — such as background-image, border-radius, font, @font-face, text-outline, text-shadow — have some extra options that you can activate by using the + sign. For example, @f+ will output:

Fuzzy Search

The CSS module uses fuzzy search to find unknown abbreviations. So, every time you enter an unknown abbreviation, Emmet will try to find the closest snippet definition. For example, ov:h and ov-h and ovh and oh will generate the same:

Vendor Prefixes

CSS3 is awesome, but those vendor prefixes are a real pain for all of us. Well, not anymore — Emmet has abbreviations for them, too. For example, the trs abbreviation will expand to:

You can also add prefixes to any kind of element. You just need to use the - prefix. So, -super-foo will expand to:

What if you don’t want all of those prefixes? No problem. You can define exactly which browsers to support. For example, -wm-trf will output:

• w → -webkit-
• m → -moz-
• s → -ms-
• o → -o-

Gradients

Speaking of annoying CSS3 features, we cannot forget gradients. Those long definitions with different notations can now be easily replaced with a concise, bulletproof abbreviation. Type lg(left, #fff 50%, #000), and the output will be:

Try It Now!

Had enough of the animated GIFs? Go ahead — type an Emmet CSS abbreviation, and hit the Tab key.

Extras

Lorem Ipsum

Forget about those third-party services that generate “Lorem ipsum” text. Now you can do that right in your editor. Just use the lorem or lipsum abbreviations. You can specify how many words to generate. For instance, lorem10 will output:

Also, lorem can be chained to other elements. So, p*3>lorem5 will generate:

Customization

Emmet offers a wide range of tweaks that you can use to fine-tune your plugin experience. There are three files you can edit to do this:

• To add your own or to update an existing snippet, edit snippets.json.
• To change the behavior of Emmet’s filters and actions, try editing preferences.json.
• To define how generated HTML or XML should look, edit syntaxProfiles.json.

And A Lot More!

This is just the beginning. Emmet has a lot of other cool features, such as encoding and decoding images to data:URL, updating image sizes and incrementing and decrementing numbers.

'Redactor' is a term, equivalent to 'editor', mostly in the Slavic languages. In other words, HTML Redactor stands for HTML Editor.

The purpose of the site is simple. It provides a handy interface to write HTML code and add it to other projects.

Write the code in the left pane and it will be rendered immediately in the right one. There are three approaches to write the code:

• Write just the text and use the editor menu to format it.
• Write all the code by hand.
• Use Zen Coding to write code with fast text-based shortcut.

Zen Coding Cheat Sheet

Zen Coding is a productivity plugin, introduced by Sergey Chikuyonok back in 2008. It then evolved in plugin named Emmet.

Writing raw HTML is slow and annoying, but with Zen Coding you have an option to speed the process up. For example, you can enter:

When you hit Tab, this code will explode into:

With a single line of text, you can add a tag with class, ID, and content. For example, the following line:

will produce:

You can generate whole tables with rows and column:

The above line will produce a table with three rows. Each row will have two columns:

Zen Coding Software

Emmet/Zen Coding is available as a plugin for many popular editors, such as Notepad++, Sublime text, PSPad and many more. HTMLRedactor.com provides it by default.
