📝 Walkthrough

Walkthrough

This pull request introduces four new Sass flexbox utility mixins (flexbox, inline-flex, align-items, order) and refactors existing stylesheet rules to use these mixins instead of float-based layouts and explicit CSS properties across multiple base and component stylesheets.

Changes

Cohort / File(s) Summary
Flexbox Mixins Foundation
app/assets/stylesheets/common/foundation/mixins.scss
Added four new public mixins: flexbox(), inline-flex(), align-items($alignment), and order($val) to provide cross-browser flexbox container and alignment declarations.
Layout Refactoring to Flexbox
app/assets/stylesheets/common/base/header.scss, app/assets/stylesheets/common/base/topic-post.scss, app/assets/stylesheets/common/base/topic.scss, app/assets/stylesheets/common/components/badges.css.scss
Replaced float-based and explicit CSS property declarations with new flexbox mixins; updated .title, .panel, .small-action, .extra-info-wrapper, and .bullet styles to use mixin-based flexbox layouts; adjusted spacing and alignment rules accordingly.

Poem

🐰 Floats fade as flexbox takes the stage,
Mixins modern, layouts engage!
Cross-browser magic, alignment so clean,
Order restored in each CSS scene,
A rabbit hops through layouts anew! 🎨

Title check ❓ Inconclusive The title 'Automated Test: header-layout-optimization-post' is vague and does not clearly describe the actual changes. The PR refactors stylesheets to use flexbox mixins across multiple files, but the title suggests only a header layout optimization and includes test-related language that is misleading. Revise the title to clearly describe the main change, such as 'Refactor stylesheets to use flexbox mixins' or 'Add flexbox utility mixins and migrate layout styles'. Remove 'Automated Test' prefix as it doesn't reflect the actual changes.

🧹 Nitpick comments (2)
app/assets/stylesheets/common/foundation/mixins.scss (1)

125-131: Potential off-by-one issue with legacy box-ordinal-group.

The legacy -webkit-box-ordinal-group and -moz-box-ordinal-group properties expect values starting from 1 (default), whereas modern order defaults to 0 and accepts negative values. If order(0) or negative values are ever used, the behavior will differ between legacy and modern browsers.

Current usages in this PR (order(2), order(3)) are safe, but consider documenting this limitation or adjusting the mixin to offset the value for legacy properties.

app/assets/stylesheets/common/base/topic-post.scss (1)

267-277: Consider removing redundant float: left on .topic-avatar.

Since .small-action is now a flex container (line 264), the float: left on line 270 is ignored by the browser. While this doesn't cause issues, removing it would improve code clarity and avoid confusion about which layout model is in effect.

⚠️ Potential issue | 🟡 Minor

-ms-align-items is not a valid CSS property.

Line 121 uses -ms-align-items which doesn't exist. The correct Microsoft prefix for this property is -ms-flex-align (already included on line 120). This line should be removed.

Additionally, note that legacy -webkit-box-align and -ms-flex-align use different value keywords than modern align-items. Values like center, baseline, and stretch work across both, but if flex-start or flex-end are ever passed, they won't work with the legacy prefixes (which expect start/end).

Proposed fix
 `@mixin` align-items($alignment) {
     -webkit-box-align: $alignment;
     -webkit-align-items: $alignment;
-    -ms-flex-align: $alignment;  
-    -ms-align-items: $alignment;
+    -ms-flex-align: $alignment;
     align-items:$alignment;
 }
