+### Content area width

+:octicons-mortar-board-24: Difficulty: _easy_
+
+The width of the content area is set so the length of each line doesn't exceed
+80-100 characters, depending on the width of the characters. While this
+is a reasonable default, as longer lines tend to be harder to read, it may be
+desirable to increase the overall width of the content area, or even make it
+stretch to the entire available space.
+
+This can easily be achieved with an [additional stylesheet][28] and a few lines
+of CSS:
+
+=== "Increase width"
+
+    ``` css
+    .md-grid {
+      max-width: 1440px;
+    }
+    ```
+
+=== "Stretch to fit"
