Writing HTML and CSS can be repetitive and time-consuming, but there's a way to write code faster without sacrificing quality. Enter Emmet, a powerful tool built into Visual Studio Code (VS Code) that enables developers to expand short snippets into complete code structures instantly. This article will introduce Emmet, explain its core features, and demonstrate how you can use it effectively in VS Code to speed up your workflow.

What is Emmet?
Emmet is a markup and stylesheet abbreviation tool that allows developers to type shorthand syntax and expand it into full-fledged HTML or CSS code. It's a lifesaver for front-end developers, eliminating the need to manually type out repetitive tags and structures. For example, typing:

ul>li*5

and pressing Tab or Enter will generate:

<ul>
    <li></li>
    <li></li>
    <li></li>
    <li></li>
    <li></li>
</ul>

By default, Emmet is already enabled in VS Code, so you can start using it immediately.

1. Expanding Abbreviations
To expand an Emmet abbreviation:
- Type the shortcut (e.g., div.container).
- Press Tab or Enter, and VS Code will expand it into:

<div class="container"></div>

2. Nesting Elements
To nest elements inside one another, use the > operator:

header>nav>ul>li*3

Expands to:

<header>
    <nav>
        <ul>
            <li></li>
            <li></li>
            <li></li>
        </ul>
    </nav>
</header>

3. Grouping with Parentheses
You can group elements using parentheses to create more complex structures:

div>(header>h1+p)+(section>p*2)

Expands to:

<div>
    <header>
        <h1></h1>
        <p></p>
    </header>
    <section>
        <p></p>
        <p></p>
    </section>
</div>

Using Emmet for CSS

Emmet also works for CSS abbreviations! For example:
Typing:

m10

Expands to:

margin: 10px;

Some advanced Emmet shortcuts to supercharge your workflow in VS Code:

4. Numbering with $
Automatically generate numbered elements:

ul>li.item$*5

Expands to:

<ul>
    <li class="item1"></li>
    <li class="item2"></li>
    <li class="item3"></li>
    <li class="item4"></li>
    <li class="item5"></li>
</ul>

5. Implicit Tag Names
Skip the tag name for common elements:

.container

Expands to:

<div class="container"></div>

6. Custom Attributes
Define attributes inside square brackets:

a[href="https://example.com" target="_blank"]

Expands to:

<a href="https://example.com" target="_blank"></a>

7. Text Content with {}
Add text inside elements:

h1{Welcome to My Website}

Expands to:

<h1>Welcome to My Website</h1>

8. Multiplication with Grouping
Use parentheses to structure complex layouts:

div>(header>h1{Title})+(section>p*2)

Expands to:

<div>
    <header>
        <h1>Title</h1>
    </header>
    <section>
        <p></p>
        <p></p>
    </section>
</div>

Expanding in Non-HTML Files
Enable Emmet in other file types like JavaScript:
- Open VS Code Settings (Ctrl + ,).
- Search for "Emmet: Include Languages".
- Add:

{
    "emmet.includeLanguages": {
        "javascript": "javascriptreact",
        "php": "html"
    }
}

Custom Snippets
Define your own Emmet shortcuts:
- Open VS Code Settings.
- Search for "Emmet: Extensions Path".
- Add a custom JSON file with your snippets.
