Question 1

What is a CSS skeleton loader?

Accepted Answer

A skeleton loader is a UI placeholder that mimics the structure of content while it's loading. Instead of showing a spinner, it renders grey blocks with a shimmer or pulse animation, giving users a sense of progress and layout.

Question 2

How do I use the generated code?

Accepted Answer

Copy the HTML and CSS using the Copy buttons and paste them into your project. The CSS uses standard @keyframes animations that work in all modern browsers.

Question 3

Can I customize the colors and animation speed?

Accepted Answer

Yes. Use the controls at the top to change the base color, highlight color, border radius, and animation duration. The preview updates in real time.

Question 4

Is it accessible?

Accepted Answer

Skeleton loaders are visually decorative. Add aria-busy='true' and aria-live='polite' to the parent container and remove the skeleton once real content loads, so screen reader users get the right signal.
