Accessibility and Text Formatting in HTML & CSS
Accessibility ensures that all users, including those using screen readers or other assistive technologies, can understand and navigate content. Text formatting plays a role in conveying meaning and emphasis in a way that is both visually and semantically correct.
Use semantic HTML tags like
<strong>,<em>,<h1>-<h6>,<p>instead of purely visual tags like<b>or<i>.Combine CSS properties like
font-weightorfont-stylewith semantic tags to style text without losing meaning.Avoid using color alone to convey information; ensure sufficient contrast for readability.
Use relative units (
em,rem) for font sizes to respect user preferences and browser zoom settings.Maintain proper line-height and spacing to improve readability for all users.
In this example, <strong> conveys meaning to assistive technologies while CSS font-weight and color enhance visual emphasis. Users relying on screen readers receive the semantic information without relying on visual styling alone.
Semantic HTML ensures accessibility while CSS enhances visual presentation.
Avoid using
<b>or<i>solely for styling; they lack semantic meaning.Proper contrast, spacing, and scalable font sizes improve readability for all users.
Combining CSS with semantic HTML strikes a balance between design and accessibility.
