Examples

1. Verifying HTML5 Void Elements

Front-end Developer

Background

A developer is refactoring a legacy codebase and wants to ensure all tags are written in modern, clean HTML5 syntax.

Problem

Unsure which tags are strictly void and if they require closing slashes.

How to use

Set 'Element Type' to 'HTML Void Elements' and enable 'Include Code Examples'.

elementType: html, includeExamples: true

Outcome

A clear list of tags like <img>, <br>, and <input> with correct syntax examples, allowing for quick cleanup of the codebase.

2. Debugging SVG Markup

UI Designer

Background

A designer is manually editing an SVG file to optimize it for a web project.

Problem

The SVG is not rendering correctly in the browser due to improper tag nesting and closing.

How to use

Set 'Element Type' to 'SVG Elements' and search for the specific tag causing issues.

FAQ

What is a void element in HTML?

A void element is an element that cannot have any child nodes, such as text or other elements. They do not require a closing tag.

Do I need to add a slash at the end of HTML void tags?

In HTML5, the trailing slash is optional for void elements. However, it is required in XHTML and recommended by some style guides for consistency.

Are SVG elements always self-closing?

No, only specific SVG elements are self-closing. Others require an explicit closing tag to function correctly within the DOM.

Can I export this reference list?

Yes, you can select JSON or Markdown as the output format to easily integrate the data into your own documentation or projects.

Does this tool cover all HTML tags?

This tool focuses specifically on self-closing (void) elements, SVG elements, and MathML elements, rather than the entire HTML specification.
