# Typography

## Typography and Accessibility

Good typography ensures that text is pleasant to read and that the content appears clearly structured. Here are some important points to consider:

1. **Clear Hierarchy**
   * The most important heading (H1) should appear only once per page.
   * This is followed by H2, H3, etc. – always in a logical order.
   * Avoid jumps, i.e., don't jump directly from H1 to H4.
2. **Appropriate Font Sizes**
   * Headings should be significantly larger than the body text.
   * Body text shouldn't be too small – 14px to 18px is ideal.
   * Very small text (e.g., on buttons) should remain easy to read.
3. **Good Readability**
   * Lines shouldn't be too long – 50 to 75 characters per line is optimal.
   * There should be enough space between lines to make the text appear airy.
   * Text should be divided into meaningful paragraphs to facilitate readability.
4. **Consider contrast**
   * The text should stand out clearly from the background (e.g., dark text on a light background).
   * Too little contrast (gray text on a gray background) makes reading difficult.
   * Color highlights should be used sparingly.
5. **Choose the right font**
   * Don't use too many different fonts – no more than two or three.
   * Serif fonts (with small decorations) have a classic and elegant look, but are more suitable for print.
   * Sans serif fonts are more modern and better for digital content.
6. **Highlight important content**
   * You can bold important terms, but not too many at once.
   * Italics should be used sparingly because they are harder to read.
   * Use underlines only for links to avoid confusion.
7. **Maintain consistency**
   * The same fonts and sizes should be used consistently throughout a document or website.
   * A consistent style appears more professional and ensures a pleasant reading experience.
