HTML
HTML (HyperText Markup Language) is the standard markup language used to create and structure web pages. It defines the structure and semantics of web content through a set of tags, encompassing elements such as text, images, hyperlinks, and tables. HTML files are parsed and rendered by browsers into visual pages. HTML is one of the core technologies of the World Wide Web and is typically used alongside CSS for styling and JavaScript for interactive behavior.
Core Facts
Tailwind CSS is an atomic CSS framework that allows styles to be written directly in HTML using predefined utility classes.
HTML was born in 1991 and was invented by Tim Berners-Lee.
When large models generate dynamic videos, they are more likely generating code that describes the animation (such as Canvas, SVG, CSS animations, or animation frameworks) rather than directly rendering pixel-level video.

All four of Willison's game projects are built on HTML and JavaScript and run entirely in the browser.
The Huashu Design project uses HTML as its primary language, lowering the barrier to contribution.
Ngezi K.D.H.S. Study Portal is built using HTML, CSS, and vanilla JavaScript.
The single-HTML-file approach suits scenarios such as offline tools, teaching demos, quick sharing, and embedded small applications, where users can run it by double-clicking with no build step or server; limitations include rising first-screen load and parse times once the file exceeds several MB, logic coupling that makes collaboration and version management difficult, and coarse caching granularity meaning any small change requires re-downloading the entire file.
The core engineering idea behind putting 500 clocks into a single HTML file is trading size for deployment convenience; compared with loading 500 separate resource files, a single file has advantages in distribution and offline use.
WordCraft can open and save docx files, and supports ODT, RTF, HTML, Markdown, LaTeX, and plain text formats.
When SVG is referenced as a standalone image via the <img> tag, external CSS does not take effect; external styles only apply when the SVG is inlined into the HTML document or embedded via <object>/<iframe>.
In HTML, furigana is implemented via the <ruby> tag; for example, <ruby>漢<rt>かん</rt></ruby> displays "かん" above the character "漢".
Current mainstream methods of adding furigana include manually entering HTML <ruby> tags, using dedicated ruby-editing software, or annotating one by one in a word processor.
The team is exploring a translation approach that preserves tags—sending serialized HTML to the LLM and asking it to return the translated HTML—but reliability is hit or miss; how to preserve the semantics of inline formatting such as bold, italics, and links in translation remains an open question to the community.
