CSS Accessibility — Code Challenge

How it works

• Accessible styling includes readable contrast, keyboard focus, flexible text sizing, and content that survives zoom. Meaning remains in the HTML while CSS helps visitors perceive it.
• Inspect the computed value as well as the declaration. Relative lengths, inheritance, and the cascade may make the final result different from a first guess.
• Prefer a small, predictable rule set. Fix the reason a declaration loses before adding more selectors or importance flags.

Your task

Use the HTML below to explore this rule: Accessible styling includes readable contrast, keyboard focus, flexible text sizing, and content that survives zoom. Meaning remains in the HTML while CSS helps visitors perceive it. Write your own CSS before opening the solution. Then replace the heading with a longer one and verify that the content is still readable.

a { text-decoration: underline; text-underline-offset: .2em; }
a:focus-visible { outline: 3px solid #835224; outline-offset: 4px; }
p { line-height: 1.7; }

A solution to compare

The HTML supplies the content; the CSS below styles it. Open both together in the playground, then change the lesson rules at the end of the stylesheet.

<article class="card"><span class="badge">This Saturday</span><h2>Neighbourhood repair club</h2><p>Bring a small project. Share a useful skill.</p><a href="#booking">View the workshop</a></article>

body { margin: 0; padding: 24px; font-family: system-ui, sans-serif; color: #25332d; background: #f4f7f2; }
.card { padding: 20px; background: white; border: 1px solid #d4dfd6; }
h2 { margin-top: 0; }
p { line-height: 1.6; }
a { color: #17634c; }
.badge { display: inline-block; margin-bottom: 12px; font-size: .8rem; }
.layout { display: grid; gap: 16px; }
.photo { width: 100%; height: 160px; background: linear-gradient(135deg, #e4af6b, #668cba); }
button, input, select { font: inherit; padding: 8px; }
label { display: block; margin-block: 12px 4px; }
