CSS one-liners can significantly enhance your web development workflow, providing quick and effective solutions for common styling challenges. Here are my top 10 CSS one-liners that you’ll find incredibly useful.

1. Aspect Ratio

Setting a fixed aspect ratio for an element is a breeze with this one-liner. It’s perfect for maintaining the dimensions of videos or images.

.box {
  width: 90%;
  aspect-ratio: 16/9;
}

2. Logical Properties

Simplify your margin and padding definitions with logical properties. These are especially handy for responsive designs.

.box {
  margin-block: 5px 10px;    /* 5px top margin, 10px bottom margin */
  margin-inline: 20px 30px;  /* 20px left margin, 30px right margin */
}

3. Centering with Flexbox

Center any element with a single line using Flexbox.

.container {
  display: flex;
  justify-content: center;
  align-items: center;
}

4. Text Overflow

Ensure long text is truncated with an ellipsis, maintaining a neat and tidy layout.

.text {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

5. Sticky Footer

Create a sticky footer that stays at the bottom of the viewport with this simple trick.

.footer {
  position: fixed;
  bottom: 0;
  width: 100%;
}

6. Variable Font Size

Make your font size responsive to the viewport width with a single line.

.text {
  font-size: calc(16px + 1vw);
}

7. Full-Width Container

Ensure your container takes up the full width of the viewport, minus any padding.

.container {
  width: calc(100% - 20px);
}

8. Custom Scrollbar

Style your scrollbar to match your design aesthetic.

::-webkit-scrollbar {
  width: 8px;
}
::-webkit-scrollbar-thumb {
  background: #888;
  border-radius: 4px;
}

9. Smooth Scroll

Enable smooth scrolling for a better user experience.

html {
  scroll-behavior: smooth;
}

10. Dark Mode

Easily switch to dark mode by leveraging CSS variables.

:root {
  --bg-color: white;
  --text-color: black;
}
body.dark-mode {
  --bg-color: black;
  --text-color: white;
}
body {
  background-color: var(--bg-color);
  color: var(--text-color);
}
