How to hero section clip-path design: css angles and custom shapes
- Step 1Choose your hero shape — The most versatile hero shapes: angled-bottom (clip-path: polygon(0 0, 100% 0, 100% 85%, 0 100%)), symmetric diamond cut (polygon(0 0, 100% 0, 100% 90%, 50% 100%, 0 90%)), or a gentle wave using the path() function.
- Step 2Apply to the hero element — Add the clip-path to your hero div. Add padding-bottom equal to the depth of the clip (e.g., if the clip drops 100px at its deepest, add padding-bottom: 100px) so the hero content doesn't overlap the clipped edge.
- Step 3Match the next section — Apply a matching angled top to the section below the hero using clip-path: polygon(0 5%, 100% 0, 100% 100%, 0 100%). This creates a continuous diagonal line between sections without gaps or misalignment.
Frequently asked questions
Why does my angled hero have a gap between it and the next section?+
The gap is caused by browser sub-pixel rendering rounding the clip boundary. Fix it by overlapping the two sections by 1–2px using a negative margin-top on the section below the hero, or by increasing the clip depth by 2px to overlap.
How do I make the hero shape responsive without media queries?+
Percentage-based polygon values automatically scale with the element. However, vertical percentage values are percentages of the element's height, not width. For a diagonal that maintains a consistent angle regardless of element height, calculate the vertical offset dynamically with CSS calc() or a small amount of JavaScript.
Can I use clip-path on a hero with a video background?+
Yes. Apply clip-path to the hero wrapper div that contains the video element. The clip applies to the entire container including the video. Ensure the video element fills the container with object-fit: cover and width/height: 100%.
Is there a performance cost to clip-path on large hero sections?+
clip-path polygon() is GPU-composited and has negligible performance cost. The path() function for curved clips may trigger paint on some browsers. For full-width hero sections over 1500px wide, prefer polygon() over path() if performance is critical.
