This code is a basic HTML document that creates a simple loading animation using CSS. Here is an analysis of the code:
1. The document starts with the `<!DOCTYPE html>` declaration, which specifies the document type and version of HTML being used.
2. The HTML document contains the following structure:
- `html` element with the `lang` attribute set to "en".
- `head` section that includes meta tags for character set and viewport settings, as well as setting the title of the document.
- `style` block within the `head` section containing CSS rules for styling the loading animation.
- `body` section that contains a `div` element with a class of "loader", which will display the loading animation.
3. In the CSS section:
- Body is styled to display flex, horizontally and vertically center the content, set the height to 100vh (viewport height), remove margin, and set the background color to a light gray.
- The loader class styles the loading animation with a width and height of 80px, a circular shape with a border, and a border that changes color during animation.
- The `@keyframes` rule defines two animations:
- `spin` animates the rotation of the circular loader with a 360-degree rotation.
- `colorChange` animates the change in border top color by progressing through different colors at specific intervals.
4. The `div` element with the class "loader" will display a spinning circular loading animation with changing colors.
Overall, this code creates a visually appealing loading animation that rotates and changes color in a loop to give a cool visual effect of a loading process.
