How to Vertically Center Text in a Div

There are several effective methods to vertically center text within a div using CSS, with the most modern and recommended approach being the CSS display: flex property. You can achieve vertical centering by adding display: flex and align-items: center to your existing CSS, or using the CSS Grid method which offers excellent browser support and is particularly useful for creating responsive layouts.

Traditional CSS Methods

Absolute Positioning with Transform

This method uses absolute positioning combined with CSS transforms:

#box {
  height: 170px;
  width: 270px;
  background: #000;
  font-size: 48px;
  color: #FFF;
  text-align: center;
  position: relative;
}

#box::before {
  content: '';
  position: absolute;
  top: 50%;
  left: 0;
  right: 0;
  height: 1px;
}

#box span {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

HTML structure needed:

<div id="box">
  <span>Lorem ipsum dolor sit</span>
</div>

This method works well but requires additional HTML markup and can be complex for simple centering tasks.

Modern CSS Flexbox Method

Flexbox is currently the most recommended method for vertical centering due to its simplicity and widespread browser support.

Basic Flexbox Implementation

#box {
  height: 170px;
  width: 270px;
  background: #000;
  font-size: 48px;
  color: #FFF;
  text-align: center;
  display: flex;
  align-items: center;
  justify-content: center;
}

This single approach handles both horizontal and vertical centering simultaneously. The align-items: center property vertically aligns items, while justify-content: center handles horizontal alignment.

Flexbox with Multiple Lines

For content that might wrap to multiple lines:

#box {
  height: 170px;
  width: 270px;
  background: #000;
  font-size: 48px;
  color: #FFF;
  display: flex;
  align-items: center;
  justify-content: center;
  flex-wrap: wrap;
  gap: 10px; /* Optional: space between wrapped lines */
}

CSS Grid Method

CSS Grid provides another modern and elegant solution for vertical centering:

Basic Grid Implementation

#box {
  height: 170px;
  width: 270px;
  background: #000;
  font-size: 48px;
  color: #FFF;
  display: grid;
  place-items: center;
}

The place-items: center is a shorthand property that sets both align-items and justify-items to center, making it incredibly concise.

Alternative Grid Method

#box {
  height: 170px;
  width: 270px;
  background: #000;
  font-size: 48px;
  color: #FFF;
  display: grid;
  align-items: center;
  justify-items: center;
}

Line Height Method

This method works well for single-line text but has limitations for multi-line content:

Single-Line Text Implementation

#box {
  height: 170px;
  width: 270px;
  background: #000;
  font-size: 48px;
  color: #FFF;
  text-align: center;
  line-height: 170px;
}

Important: The line height must equal the container height. For responsive designs where height might change, this method becomes less practical.

Modified Line Height Method

#box {
  height: 170px;
  width: 270px;
  background: #000;
  font-size: 48px;
  color: #FFF;
  text-align: center;
  line-height: normal;
  display: inline-block;
  vertical-align: middle;
}

#box::after {
  content: '';
  display: inline-block;
  height: 100%;
  vertical-align: middle;
}

Table Cell Method

This method mimics traditional table layout behavior:

Implementation

#box {
  height: 170px;
  width: 270px;
  background: #000;
  font-size: 48px;
  color: #FFF;
  text-align: center;
  display: table-cell;
  vertical-align: middle;
}

This approach provides good compatibility but can be less intuitive than modern CSS methods and may have performance implications in complex layouts.

Comparison of Methods

Recommendation Summary

• For modern web development: Use Flexbox (display: flex + align-items: center)
• For grid-based layouts: Use CSS Grid (display: grid + place-items: center)
• For single-line text: Use Line Height method for simplicity
• For legacy support: Consider Table Cell method

Browser Compatibility Considerations

Modern Methods (Flexbox & Grid)

Both Flexbox and CSS Grid have excellent browser support in modern browsers:

• Flexbox: Supported by all modern browsers including IE11+ with vendor prefixes
• CSS Grid: Supported by all modern browsers including IE10+ with vendor prefixes

Legacy Support

For older browsers like Internet Explorer 8 and 9, you might need fallback methods:

#box {
  /* Modern browsers */
  display: flex;
  align-items: center;
  justify-content: center;
  
  /* Fallback for IE9 */
  display: -ms-flexbox;
  -ms-flex-align: center;
  -ms-flex-pack: center;
  
  /* Fallback for IE8 */
  display: table;
  vertical-align: middle;
}

Conclusion

Vertically centering text in a div is a common CSS requirement with multiple solutions available. The best modern approach is using Flexbox with display: flex, align-items: center, and justify-content: center properties, as it provides excellent browser support, simple implementation, and works well with responsive designs.

For your specific example with the black div containing white text, simply add these three properties to your existing CSS:

#box {
  /* Your existing properties */
  height: 170px;
  width: 270px;
  background: #000;
  font-size: 48px;
  color: #FFF;
  text-align: center;
  
  /* Add these for vertical centering */
  display: flex;
  align-items: center;
  justify-content: center;
}

This solution will work across all modern browsers and provides the most maintainable code for future development. If you’re working on a project with specific legacy browser requirements, consider using the line height method for single-line text or the table cell method as a fallback option.
