Output (EM):

  1. Scalability and Responsiveness: Em units scale with the screen resolution. For example, 1em might be 12px on one screen but 16px on a larger screen. This makes em a good choice for responsive design.
  2. Relative to Font Size: Em depends on the font size of the current element. When you change the base font size, em units adjust accordingly. Use em for typography and other scalable elements that need to change size relative to their parent element.
  3. Margin and Padding: Em is recommended for setting margin and padding. When you use em for these properties, they adjust according to the font size of the parent element.
  4. Flexible Layouts: Em allows you to create flexible and responsive designs. It’s especially useful when you need to scale an element consistently with its parent.
  5. Font Sizing: Em is great for precise font sizing. Unlike px, which remains fixed, em adapts to the chosen font size.
  6. Dynamic Changes: Em can change dynamically with the font in use, making it suitable for positioning and spacing around text elements like line-height.
  7. Mix of Units: While em is beneficial, a mix of units (including px) is often necessary. For example, images are scaled based on pixels, so you’ll need px units when designing around an image.
  8. Maintainability: Em is the most maintainable choice. Since it depends on the font size, it scales along when you change the base font size.
  9. Responsive Typography: Use rem (root em) for scalable typography that changes relative to the root element. This ensures consistent font sizing across the entire page.
  10. Design Flexibility: Em provides a balance between fixed and flexible sizing. Use it wisely based on your design requirements.

Line Height:

  • Set the line height of text using em units to maintain consistent spacing between lines. For example:
p {
  line-height: 1.5em; /* 1.5 times the font size of the paragraph */

Margin and Padding Around Text:

  • Use em units for margins and padding around text elements. This ensures that spacing adjusts proportionally with the font size. For instance:
.button {
  margin: 0.5em; /* Creates a margin of half the font size */
  padding: 0.75em; /* Padding equivalent to 0.75 times the font size */

Responsive Font Sizing:

  • Implement responsive font sizes by using em units. When the user adjusts their browser font size, the text scales accordingly. Example:
h1 {
  font-size: 2em; /* Twice the font size of the parent element */

EM units are relative to the font size of the parent element, making them more adaptable to different screen sizes and accessibility settings.

How do I convert PX to EM values?

Divide the desired pixel value by the parent element’s font size in pixels.

Can I use EM units for all CSS properties?
