Flex vs. Justify-Content vs. Text-Align: How to Choose the Right CSS Alignment Method?

What is the Difference Between "Flex" and "Justify-Content" vs. "Text-Align"?

Align elements within a container using CSS is a common task. While "text-align" is a traditional approach, "flex" and "justify-content" offer more flexibility and control.

How They Differ

"Text-align" primarily aligns inline elements (text) within their container. However, it has limited capabilities when dealing with multiple block-level elements (e.g., buttons).

In contrast, "flex" and "justify-content" are part of the Flexbox layout module. Flexbox allows for precise control over the alignment, distribution, and sizing of block-level elements. "Justify-content" specifically controls how elements are aligned along the main axis of the container.

When to Choose Flex

Flexbox excels when there are multiple block-level elements and precise alignment is required. Here are examples where text-align may not suffice:

• Justifying Buttons on Both Sides: Flexbox can align buttons to both the left and right sides of a container, while text-align only allows alignment to one side.
• Multiple Text Blocks with Different Alignments: Flexbox can align text blocks with different alignments (left, center, right) within the same container.
• Complex Layouts: Flexbox provides more control over the layout and spacing between elements, enabling the creation of complex and responsive layouts.

Example

In the following example, the container has two buttons. Using "text-align" moves them both to the right, while using "flex" allows them to be justified at the end of the container:

<div class="parent">
  <button>Button 1</button>
  <button>Button 2</button>
</div>

.parent {
  text-align: right;  /* Using "text-align" */
}

.parent {
  display: flex;
  justify-content: flex-end;  /* Using "flex" and "justify-content" */
}

Conclusion

While "text-align" remains useful for aligning inline elements, "flex" and "justify-content" provide greater flexibility and control over block-level elements. By leveraging Flexbox, developers can create more complex and responsive layouts, ensuring proper alignment and distribution in various scenarios.
