+  * The key design approach that you need to adopt is called **Progressive enhancement**.((This also applies to behaviour, and we will study it in more depth next year when we look at JavaScript))
-                (+ Boon)
+  * In summary you need to separate HTML from styles so that you can progressively enhance the layout for higher resolution and more capable devices
-Principles:

+  * Flexible images and media
+  * Use of media queries
+----
+<note>
+  * //A flexible grid-based layout// uses so-called fluid layout so that width/margin/padding of elements are defined in percentages or ems rather than pixels. This makes the location and size of all elements relative and easily resizable.
+  * //Flexible images and media// means that images and video are sized by percentages which can be scaled up or down. This may require server-side support for scaling if it is to be efficient on mobile devices.
+  * //Use of media queries// -- a CSS3 feature -- that allows you to adjust the design based on device features such as the width of the device's viewable area.
