A clip path generator example is a ready-made polygon() declaration such as polygon(50% 0%, 0% 100%, 100% 100%) that clips an HTML element to a triangle using percentage-based coordinates read in drawing order. A dedicated generator gives you a visual preset, an editable coordinate list, and a live preview so you can see the resulting shape before you copy the CSS. Because polygon() uses percentages, the same example scales with the element's width and height rather than locking to fixed pixels, which makes it useful for responsive layouts and reusable components. The generator validates each coordinate pair, rejects malformed input, and serializes a clean declaration you can paste into a stylesheet or inline style attribute. Each clip-path example shares a few properties: every point is an x percentage followed by a y percentage, vertices are separated by commas, and the browser automatically closes the polygon by drawing a straight segment from the last point back to the first. That combination of editing, previewing, and validation is what turns a single clip-path example into a working snippet instead of a guess.
What a CSS Clip Path Generator Does
The CSS Clip Path Generator is a browser-based editor for the percentage polygon form of CSS clip-path. It starts from eight useful presets — triangle, diamond, pentagon, hexagon, star, chevron, message bubble, and parallelogram — so you do not have to invent every vertex from an empty list. Once a preset is loaded, the tool exposes its coordinate list as comma-separated x% y% pairs in drawing order. You can replace any value, add a vertex, or remove one, up to a hard cap of twenty points. Every edit is validated against the same rules the browser applies: percentages must be between 0 and 100, every pair must include both an x and a y, and the percent sign is required. Decimal values are accepted and normalized, so 33.33% 0% is treated the same as 33.3% 0% in the output. A live preview block receives the current polygon() value, which lets you judge the shape at the element's intended aspect ratio before you commit the CSS to your project. Generation runs entirely in the browser; no coordinates are uploaded or stored.
Clip Path Generator Examples for Common Shapes
The eight built-in presets double as concrete clip path generator examples you can copy and adapt. Each one is defined purely as percentage coordinates, which is why the same declaration behaves predictably across different element sizes. The table below lists a representative polygon() declaration for each preset, the number of points it uses, and the visual outline it produces.
| Shape | Example polygon() declaration | Points | Outline |
|---|---|---|---|
| Triangle (up) | polygon(50% 0%, 0% 100%, 100% 100%) | 3 | Equilateral triangle pointing up |
| Diamond | polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%) | 4 | Rhombus inscribed in the reference box |
| Pentagon | polygon(50% 0%, 100% 38%, 82% 100%, 18% 100%, 0% 38%) | 5 | Regular five-sided polygon |
| Hexagon | polygon(25% 0%, 75% 0%, 100% 50%, 75% 100%, 25% 100%, 0% 50%) | 6 | Flat-top regular hexagon |
| Star (5-point) | polygon(50% 0%, 61% 35%, 98% 35%, 68% 57%, 79% 91%, 50% 70%, 21% 91%, 32% 57%, 2% 35%, 39% 35%) | 10 | Five-pointed star with alternating outer and inner vertices |
| Chevron (right) | polygon(0% 0%, 75% 0%, 100% 50%, 75% 100%, 0% 100%, 25% 50%) | 6 | Right-pointing arrow with concave left edge |
| Message bubble | polygon(0% 0%, 100% 0%, 100% 75%, 75% 75%, 75% 100%, 50% 75%, 0% 75%) | 7 | Rounded rectangle with downward tail |
| Parallelogram | polygon(15% 0%, 100% 0%, 85% 100%, 0% 100%) | 4 | Slanted four-sided shape |
Two details matter when reading these examples. First, the order of points is the drawing order, and reordering the same set of coordinates produces a different outline. Second, concave shapes such as the star and the chevron deliberately fold inward; the browser still treats every segment as a straight line, so the inward angle is what gives those presets their recognizable silhouette. Self-intersecting polygons can render in surprising ways because the CSS Shapes specification leaves the fill rule to the user agent, which is why the generator validates syntax but does not guarantee that every point order looks visually useful. The clip path generator examples above all use values inside the 0 to 100 range, which keeps every vertex on or inside the reference box even though CSS itself allows points outside it. For a deeper reference of valid coordinate pairs, see the clip path generator cheat sheet on polygon coordinates.
Generate a Clip Path Step by Step
The shortest path from a blank page to a working declaration is to start from a preset, edit the coordinates one vertex at a time, and confirm the result at the real aspect ratio. The CSS Clip Path Generator follows four concrete steps.
- Choose the preset closest to the shape you need — triangle, diamond, pentagon, hexagon, star, chevron, message bubble, or parallelogram.
- Edit comma-separated x% y% coordinate pairs in drawing order; decimal values are normalized, and validation rejects missing percent signs, negatives, or values above 100.
- Check the preview at the intended element aspect ratio rather than only at the default square, because percentage coordinates scale with the reference box.
- Copy the declaration and test layout, focus, and responsive behavior on the target page, including any browser that needs a rectangular fallback.
Why Percentage Coordinates Stretch Across Boxes
Polygon coordinates in CSS are percentages of the element's reference box, which is normally the border box when no explicit geometry is supplied. That is why the same clip path generator example can look balanced on a square element and stretched on a wide rectangle. The coordinates themselves never change, but the visible proportions do, because the x and y axes are scaled independently to the element's actual width and height. A diamond built from polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%) sits at the corners of any rectangular reference box, but the diagonal aspect ratio of the visible diamond matches the box's aspect ratio: wider boxes produce wider diamonds, taller boxes produce taller ones. Always preview the same declaration at the width and height your layout will actually use, and across each breakpoint where the element resizes. The W3C CSS Shapes Module Level 1 describes this geometry behavior, and the MDN clip-path reference lists the property's supported values and browsers.
Accessibility, Layout, and Performance Notes
Clip-path hides pixels but does not change layout. The element still occupies its original rectangular box, so surrounding content does not reflow to fit the clipped silhouette. That distinction matters for focus rings, touch targets, and any interactive element where part of the clickable region has been cut away. Do not clip away essential text, keyboard focus indicators, or hit areas, and avoid using a decorative silhouette as the only signal of a control's purpose. For images, preserve the meaningful alternative text even when only a fragment is visible; for animated transitions, keep the same vertex count and a compatible order between the start and end polygons so the browser can interpolate cleanly. Performance-wise, a visually clipped image still downloads at its original dimensions, so combine clip-path with appropriately sized source files. Check browser support for the percentage polygon form required by your audience, and provide a sensible rectangular fallback when the silhouette is decorative rather than essential. The W3C CSS Shapes Module Level 1 and the MDN clip-path reference both describe these constraints in their respective specifications.
