HTML Tag Names

0.1.2 · active · verified Sat Apr 11

This library provides a static list of known HTML tag names, encompassing both historical and current tags as defined by the HTML living standard. It is a Python port of the popular npm package `html-tag-names`. The current version is 0.1.2, with releases typically occurring infrequently, primarily for data updates or minor maintenance.

Warnings

gotcha The `html-tag-names` list includes all known HTML tags, which means it contains many deprecated or obsolete tags (e.g., `<font>`, `<center>`, `<marquee>`) alongside modern ones. Developers should be aware of current HTML standards (HTML5+) and use CSS for presentation rather than relying on deprecated HTML tags.
Fix: Consult current HTML specifications and prioritize semantic HTML5 tags and CSS for styling. Use this list as a comprehensive reference, but not as a prescriptive guide for modern web development.
gotcha All tag names in the `html_tag_names` list are in lowercase. If comparing against sources or inputs that might use uppercase or mixed-case HTML tag names, conversion to lowercase will be necessary for accurate checks.
Fix: Always convert input tag names to lowercase before checking against `html_tag_names` (e.g., `my_tag.lower() in html_tag_names`).
gotcha This library provides a static list of tag names for reference. It does not offer any HTML parsing, validation, manipulation, or rendering capabilities. It is simply a data source of valid tag names.
Fix: For tasks like parsing HTML documents, extracting content, or validating HTML structure, consider using dedicated libraries such as Beautiful Soup (`beautifulsoup4`).

Quickstart

This quickstart demonstrates how to import the list of HTML tag names and perform basic operations like checking its length, viewing elements, and testing for the presence of specific tags.

from html_tag_names import html_tag_names

print(f"Total HTML tags: {len(html_tag_names)}")
print(f"First 5 tags: {html_tag_names[:5]}")

if 'div' in html_tag_names:
    print("'div' is a known HTML tag.")

# Example of checking for a deprecated tag (which are included)
if 'font' in html_tag_names:
    print("'font' is in the list, though it is a deprecated tag.")
