Question

What does bolding do to text?

Answer 1

Bolding makes text visually heavier/darker by increasing the stroke weight of the letters. That visual change is used to attract attention and create hierarchy. Key points:

What it does
- Emphasizes words or phrases so they stand out when scanning.
- Establishes hierarchy (headings, subheads, labels).
- Improves quick recognition of key terms or values.
- Can aid readability for some users (especially at small sizes or low contrast), but large blocks of bold text are harder to read.

Semantic vs. purely visual
- In semantics-aware formats there’s a difference: <strong> (HTML) signals importance to browsers and assistive tech, while <b> is purely presentational. Screen readers may announce <strong> differently.
- In plain visual editors (Word, Google Docs, Markdown **text**) bold is typically just visual.

How to apply (common syntaxes)
- Markdown: **bold text** or __bold text__
- HTML: <strong>important</strong> (semantic) or <b>bold</b> (visual)
- CSS: font-weight: bold; or font-weight: 700;
- Rich editors: usually a Bold button or Ctrl/Cmd+B

Accessibility & typography tips
- Use bold sparingly — too much reduces its effectiveness and makes pages harder to read.
- Don’t rely on bold alone to convey meaning (also use labels, structure, or semantic markup) so people using screen readers or color-blind users aren’t disadvantaged.
- Prefer bold for short chunks (words, short phrases, headings), not long paragraphs.
- Ensure sufficient contrast with the background; bold doesn’t fix poor contrast.
- Be mindful of fonts: some fonts don’t have a true bold weight and browsers may fake it, which can look poor.

In short: bolding visually highlights and orders content; use it intentionally and sparingly, and use semantic markup (like <strong>) when the emphasis is meaningful.
