+# Functions & Directives
+
+Tailwind exposes a few CSS functions and directives that can be used in your actual CSS files.
+
+## @tailwind
+
+Use the `@tailwind` directive to insert the Tailwind reset styles and utilities into your CSS file. Here is a full example of how you might do this:
+
+```less
+/**
+ * This injects Tailwind's base styles, which is a combination of
+ * Normalize.css and some additional base styles.
+ *
+ * You can see the styles here:
+ * https://github.com/nothingworksinc/tailwindcss/blob/master/css/preflight.css
+ */
+@tailwind  reset;
+
+/**
+ * Here you would import any custom component classes; stuff that you'd
+ * want loaded *before* the utilities so that the utilities can still
+ * override them.
+ */
+@import  "my-components/foo";
+@import  "my-components/bar";
+
+/**
+ * This injects all of Tailwind's utility classes, generated based on your
+ * config file.
+ */
+@tailwind  utilities;
+
+/**
+ * Here you would add any custom utilities you need that don't come out of the box with Tailwind.
+ */
+.bg-hero-image {
+    background-image: url('/some/image/file.png');
+}
+```
+
+## @responsive
+
+You can generate responsive versions of your own utilities by wrapping their definitions in the `@responsive` directive:
+
+```less
+@responsive {
+  .bg-gradient-brand {
+    background-image: linear-gradient(blue, green);
+  }
+}
+```
+
+This will generate these classes (assuming you haven't changed the default breakpoints):
+
+```less
+.bg-gradient-brand {
+  background-image: linear-gradient(blue, green);
+}
+@media (min-width: 576px) {
+  .sm\:bg-gradient-brand {
+    background-image: linear-gradient(blue, green);
+  }
+}
+@media (min-width: 768px) {
+  .md\:bg-gradient-brand {
+    background-image: linear-gradient(blue, green);
+  }
+}
+@media (min-width: 992px) {
+  .lg\:bg-gradient-brand {
+    background-image: linear-gradient(blue, green);
+  }
+}
+@media (min-width: 1200px) {
+  .xl\:bg-gradient-brand {
+    background-image: linear-gradient(blue, green);
+  }
+}
+```
+
+## @screen
+
+Say you have a `sm` breakpoint at `576px`, and you need to write some custom CSS that references this breakpoint.
+
+Instead of duplicating the values like this:
+
+```less
+@media (min-width: 576px) {
+  /* ... */
+}
+```
+
+...you can use the `@screen` directive and pass the breakpoint name:
+
+```less
+@screen sm {
+  /* ... */
+}
+```
+
+## config()
+
+With all your variables defined in your JavaScript-based Tailwind config file, you may be wondering how you access those values in your custom CSS. This can be done using the `config()` helper function. Here is an example:
+
+```less
+.error {
+  font-size: config('textSizes.xs');
+  color: config('colors.slate-darker');
+}
