Flexbox or Text-Align: Which is Best for Right-Aligning Elements?

Flexbox vs. Text-Align: Aligning Elements Rightward

While both "text-align" and "flex" properties can be used to move an element to the right of its parent, there is a fundamental difference in their functionality.

Text-Align

"Text-align" is primarily used to control the alignment of text content within inline elements such as spans or headings. It has no effect on block-level elements like buttons or div containers.

When aligning block-level elements rightward using "text-align", it only adjusts the placement of the element's content (e.g., text, icons), not the element itself. This can result in unexpected behavior when multiple elements are placed side-by-side.

Flexbox

Flexbox (short for Flexible Box Layout) is a CSS layout module that allows for more advanced layout control. Unlike "text-align", flexbox directly controls the positioning and alignment of block-level elements within a container.

When using flexbox, the "justify-content" property determines the distribution of child elements along the main axis of the container. Setting "justify-content" to "flex-end" aligns elements to the right.

Reasons to Choose Flexbox over Text-Align

• Multiple Elements: Flexbox allows for precise alignment of multiple block-level elements within a container, accommodating complex layouts where elements have varying widths or heights.
• Responsive Alignment: Flexbox can be used to create responsive layouts that automatically adjust the alignment of elements based on the screen size or viewport.
• Compatibility: Flexbox is supported in all major browsers, ensuring cross-browser consistency.

Example: Bootstrap Modal Footer Alignment

Bootstrap changed from using "text-align: right" to flexbox in version 4 for the purpose of button alignment in modal footers. This change provides consistent alignment of buttons within the modal, regardless of the number or size of buttons, and ensures a more responsive and user-friendly layout.
