Question 3

How do I make a perfect circle with CSS?

Accepted Answer

Use border-radius: 50% on an element with equal width and height. The 50% means the radius is half the element's size, creating a perfect circle. For a responsive circle: width and height both set (or use aspect-ratio: 1), plus border-radius: 50%. For an oval/ellipse, use border-radius: 50% on an element with unequal dimensions.

Question 4

What is the CSS border-radius syntax?

Accepted Answer

Shorthand: border-radius: 10px (all corners equal). Two values: 10px 20px (TL+BR, TR+BL). Four values: 10px 20px 30px 40px (TL, TR, BR, BL — clockwise). Eight values with slash: border-radius: 30% 70% / 70% 30% (horizontal radii / vertical radii — for elliptical corners). Individual properties: border-top-left-radius, border-top-right-radius, border-bottom-right-radius, border-bottom-left-radius.

Question 5

How do I make a perfect CSS circle?

Accepted Answer

1) Fixed size: .circle { width: 100px; height: 100px; border-radius: 50%; }. 2) Responsive: .circle { width: 100%; aspect-ratio: 1; border-radius: 50%; }. Width must equal height for a circle — if they differ, border-radius: 50% creates an ellipse. For profile photos: width: 80px; height: 80px; border-radius: 50%; object-fit: cover; ensures the image fills the circle correctly.

Question 6

How do I create an organic blob shape?

Accepted Answer

Blob shapes use the 8-value format: border-radius: X1% X2% X3% X4% / Y1% Y2% Y3% Y4%;. Example: border-radius: 30% 70% 70% 30% / 30% 30% 70% 70%; creates a teardrop-like shape. Use this tool's Blob Generator to create random organic shapes and the Animate button to see continuous morphing, then copy the CSS for the frame you want. Values can be animated with CSS transitions or JavaScript setInterval for living blob effects.

Question 7

What is the difference between px and % for border-radius?

Accepted Answer

Pixel values (px): fixed radius regardless of element size. border-radius: 8px gives identical corner curves on a 100px or 1,000px element. Good for consistent card corners. Percentage (%): radius scales proportionally with element size. border-radius: 50% on any equal-width/height element creates a circle regardless of size. On a 200×100 element, 50% creates 100px horizontal and 50px vertical radii — an ellipse.
