Pull Request Overview
This PR optimizes header layout performance by introducing reusable flexbox mixins and refactoring existing CSS to use flexbox instead of float-based layouts. The changes aim to modernize the layout approach for better performance and maintainability.
- Adds comprehensive flexbox mixins (flexbox, inline-flex, align-items, order) with vendor prefixes
- Replaces float-based layouts with flexbox in header, topic, and component styles
- Removes redundant margin and padding adjustments that were needed for float layouts

Missing space after colon. Should be align-items: $alignment; for consistency with other CSS properties.

Trailing whitespace should be removed for cleaner code.

The align-items mixin accepts any value but flexbox align-items has specific valid values (stretch, center, flex-start, flex-end, baseline). Consider adding validation or documentation for expected values.
| @mixin align-items($alignment) { | |
| -webkit-box-align: $alignment; | |
| -webkit-align-items: $alignment; | |
| -ms-flex-align: $alignment; | |
| -ms-align-items: $alignment; | |
| align-items:$alignment; | |
| // Mixin to set the align-items property in Flexbox | |
| // Valid values for $alignment: stretch, center, flex-start, flex-end, baseline | |
| @mixin align-items($alignment) { | |
| @if not index(("stretch", "center", "flex-start", "flex-end", "baseline"), $alignment) { | |
| @error "Invalid value '#{$alignment}' for align-items. Valid values are: stretch, center, flex-start, flex-end, baseline."; | |
| } | |
