- Around line 125-131: The mixin order currently passes the 0-based $val
directly to -webkit-box-ordinal-group which expects a 1-based value; update the
mixin (named order) to set -webkit-box-ordinal-group to $val + 1 (i.e., convert
the 0-based order to 1-based) while leaving -ms-flex-order, -webkit-order and
order unchanged so old WebKit browsers receive the corrected ordinal-group
value.
- Around line 117-123: The mixin align-items contains an invalid CSS property
(-ms-align-items); remove the -ms-align-items declaration from the `@mixin`
align-items so only valid vendor-prefixed properties remain (keep
-webkit-box-align, -webkit-align-items, -ms-flex-align) and the standard
align-items:$alignment; entry.

95-114: Consider whether these legacy vendor prefixes are still needed.The
-webkit-box-*,-moz-box-*, and-ms-flexboxprefixes target browsers from 2012–2014 (e.g., Android Browser 4.x, Firefox < 28, IE 10). If the application's browser support matrix doesn't include these, you can simplify the mixins significantly—or replace them entirely with Autoprefixer, which generates only the prefixes your targets require.This is a non-blocking observation for the team to consider.

-ms-align-items (line 121) is not a valid CSS property.
The correct IE10 prefix for align-items is -ms-flex-align, which is already present on line 120. -ms-align-items is unrecognized and has no effect—it should be removed.
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;

-webkit-box-ordinal-group is 1-based; passing $val directly is off-by-one.
The legacy -webkit-box-ordinal-group property uses 1-based values, whereas the standard order is 0-based. For example, order: 2 should correspond to -webkit-box-ordinal-group: 3. Passing $val unchanged will mis-order elements in old WebKit browsers that rely on the prefixed property.
Proposed fix
`@mixin` order($val) {
- -webkit-box-ordinal-group: $val;
+ -webkit-box-ordinal-group: $val + 1;
-moz-box-ordinal-group: $val;
-ms-flex-order: $val;
