-# Constrain
-
-The constrain utilities are simply `max-width` helpers designed to constrain content to a desired width.
-
-```html
-<!-- Using the utilities in HTML: -->
-
-<div class="constrain-xl">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
-tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,

-
-## Customization
-
-Tailwind exposes the following variables to allow modification of the constrain utilities.
-
-```less

+
+Construct border size utilities using the `.border{-side?}{-width?}` syntax. For example, `.border` would add a `1px` border to all sides of the element, where `.border-b-4` would add a `4px` border to the bottom of the element. By default, borders are `solid`, and use the `@default-border-color`.

+
+```html
+<!-- Add a 1px border to all sides -->
+<div class="border"></div>
+
+<!-- Add a 1px border to the top side -->
+<div class="border-t"></div>
+
+<!-- Add a 2px border to the top side -->
+<div class="border-t-2"></div>
+```
+
+```less
+// Using the border size utilities in Less
+div {
+    .border;
+    .border-t;
+    .border-t-2;
+}
+```
+
+### Customizing border sizes
+
+You can easily customize the border size utilities using the `@border-width-scale` variable. Please note that the entire scale must be redefined. It's not possible to add a new value to the existing scale.
+
+```less
+// The default border width scale
+@border-width-scale:
+  '0' 0,
+  default 1px,
+  '2' 2px,
+  '4' 4px,
+  '8' 8px,
+;
+```

+By default, borders use the `@default-border-color`. To override a border color, add one of the border color utilities.
+
+```html

+<div class="border border-dark-soft"></div>
+<div class="border border-dark-softer"></div>

+```
+
+The default border colors can also be modified using the following variables.
+
+```less
+// Variable:            Default:
+@border-dark:           hsl(0, 0%, 82%);

+
+You can customize the margin and padding utilities using the `@sizing-scale` variable. Please note that the entire scale must be redefined. It's not possible to add a new value to the existing scale.
+
+```less
+// The default sizing scale
+@sizing-scale:
+  '1' 0.25rem,
+  '2' 0.5rem,
+  '3' 0.75rem,
+  '4' 1rem,
+  '6' 1.5rem,
+  '8' 2rem,
+  '12' 3rem,
+  '16' 4rem,
+;
+```
+
+By default the `@sizing-scale` is automatically applied to the margin, negative margin (pull) and padding scales. However, it's possible to customize each scale individually using the `@margin-scale`, `@pull-scale` and `@padding-scale` variables.
+
+```less
+// Override the margin scale
+@margin-scale:
+  '1' 0.25rem,
+  '2' 0.5rem,
+  // ...
+;
+
+// Override the pull scale
+@pull-scale:
+  '1' 0.25rem,
+  '2' 0.5rem,
+  // ...
+;
+
+// Override the padding scale
+@padding-scale:
+  '1' 0.25rem,
+  '2' 0.5rem,
