When should I use strong vs b and em vs i?
Strong and em carry semantic weight - strong means the content is important and em means stressed emphasis, both of which screen readers convey. The b and i tags are purely presentational, used when text needs to look bold or italic without implying meaning, such as keywords, technical terms, or ship names. Use the semantic tags whenever the meaning matters.
What does the mark tag do?
Mark highlights text the way a yellow highlighter does on paper, indicating relevance to the reader's current context - for example, search-result terms or annotations a user added. By default browsers render it with a yellow background, but you can restyle it freely. Avoid using mark merely for decoration; use a span with a class instead so the semantics stay accurate.
How is code different from pre and kbd?
Code marks an inline fragment of computer code such as a variable name or function call. Pre preserves whitespace and is typically wrapped around a code block to keep indentation. Kbd represents user keyboard input like Ctrl+C. Combine them: a multi-line snippet uses pre containing code, while keyboard shortcuts use kbd. Each tag carries different semantics for assistive tech and search engines.
Should I use small for fine print?
Yes - small is intended for side comments and small print like copyright notices, legal disclaimers, and licensing details. It is a semantic tag, not just a font-size shortcut, so it tells assistive technology that the content is supplementary. If you only need smaller text without that meaning, apply CSS font-size to a span or div instead.
What are sub and sup used for in real content?
Sub renders subscript text, useful for chemical formulas like H2O and mathematical indices. Sup renders superscript, used for exponents like x squared, footnote markers, and ordinals like 1st. Both are inline elements, so they flow with surrounding text. Avoid using them just for visual lift on dates or symbols where typography would be a better fit.
Are deprecated tags like big, font, or center supported?
No. Those tags were removed in HTML5 and modern browsers may render them inconsistently or drop support entirely. Use CSS for sizing, color, and alignment instead. The generator only outputs valid HTML5 text tags, so anything you copy from it will pass HTML validators and behave predictably across browsers and email clients that support modern markup.
