Introduction to pb-[15vh]: What Does it Mean?
The CSS class pb-[15vh] may sound like a cryptic code at first, but understanding it is simpler than you think. Here, pb refers to padding-bottom, a property you can use to add space below an element. The value 15vh is a responsive unit based on the viewport height. This means the padding will adjust dynamically depending on the height of the browser window.
For example, if the viewport is 800px tall, 15% of that height (or 15vh) equals 120px of padding below the element.
By using pb-[15vh], you ensure your designs are fluid and create a consistent user experience across devices. This technique is frequently used in modern, responsive web design.

vhadjusts spacing dynamically. - Improves UX: Consistent spacing enhances readability and doesn’t cut off content on smaller devices.

| CSS Unit | Definition | Example Value |
|---|---|---|
| px | Fixed pixel value | 20px |
| em | Relative to font-size of the element | 1.5em |
| vh | Percent of viewport height | 15vh |
| % | Relative to its parent element | 30% |
