Coding Format Html Essentials for Front-end Development

Coding format is crucial for front-end development, and HTML is the foundation of it all. A well-structured HTML document is essential for readability and maintainability.

Indentation is key in HTML, with each level of nesting indented four spaces. This makes it easy to see the structure of the document.

A consistent naming convention is also important, with element names and IDs following a logical pattern. In the article, we discussed how to use a consistent naming convention for HTML elements.

Using a consistent naming convention helps prevent naming conflicts and makes the code easier to understand.

HTML formatting can be achieved using the Format Document command in VS Code, which is based on js-beautify. This command can be accessed by pressing ⇧⌥F (Windows Shift+Alt+F, Linux Ctrl+Shift+I).

The HTML formatter offers various options, including setting the maximum amount of characters per line and specifying tags that shouldn't be reformatted. You can find these options in the VS Code settings under the html.format section.

To preserve line breaks before elements, you can set html.format.preserveNewLines to true. This can be particularly useful when working with preformatted text or code blocks.

Formatting your HTML code is crucial to improve readability and maintainability. You can use the Format Document command to format the entire file or Format Selection to just format the selected text.

The HTML formatter is based on js-beautify, which offers various formatting options. These options can be accessed through the VS Code settings, including html.format.wrapLineLength, html.format.unformatted, and html.format.contentUnformatted.

To customize the formatting, you can adjust the settings to suit your needs. For example, you can set html.format.extraLiners to list the tags that should have an extra newline before them.

The formatter can be turned off by setting "html.format.enable": false in your settings. This allows you to use a different formatter if you prefer.

Here are some key settings to consider:

Note that embedded JavaScript is formatted unless 'script' tags are excluded. If you want to use a different formatter, you can define "html.format.enable": false in your settings to turn off the built-in formatter.

Auto Update Tags is a feature that can save you a lot of time and effort when editing HTML code.

Linked editing is how it works, automatically updating the matching closing tag whenever you modify a tag. This feature is optional, and you can enable it by setting.

This means you don't have to manually update the closing tag every time you make a change, which can be a real time-saver.

The color picker is a powerful tool in HTML formatting and editing. It allows you to configure the hue, saturation, and opacity of the color picked up from the editor.

You can also trigger between different color modes by clicking on the color string at the top of the picker. This gives you more control over the color palette.

The picker appears on a hover when you are over a color definition, making it easy to access and adjust colors as you work.

You can enhance VS Code's HTML support by using a declarative custom data format, which allows you to provide a list of JSON files that follow the custom data format. This will enable language support such as completion and hover information for new HTML tags, attributes, and attribute values.

To take your HTML coding to the next level, consider installing an extension from the Extensions view. Simply type 'html' to see a list of relevant extensions that can help with creating and editing HTML.

Some popular extensions include CSS, SCSS, and Less, which offer first-class support for CSS, including Less and SCSS. Emmet is another powerful tool that provides a wide range of features for web developers.

Here are some popular extensions for HTML:
