CSS Border Images — Code Challenge
Put paint a decorative border image into practice. Rebuild the example from its HTML, then compare your result with the CSS solution. Change the content and the viewport before calling it finished.
How it works
- Border-image slices a source into regions used around the border. A gradient can be used as that source without requesting an external image.
- A decorative effect should leave the content understandable when the effect is unavailable. Provide a readable background and normal document flow first.
- Inspect clipping, stacking, and contrast when adding layers; appearance changes do not always change the layout box.
Your task
Use the HTML below to explore this rule: Border-image slices a source into regions used around the border. A gradient can be used as that source without requesting an external image. Write your own CSS before opening the solution. Then replace the heading with a longer one and verify that the content is still readable.
Review the CSS solution
.card { border: 12px solid transparent; border-image: linear-gradient(45deg, #bf7c39, #2b7053) 1; }
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; }
