 Background shapes
 =================
 
 Background shapes are SVG files that you can add as a decorative background in your different
 sections. Each shape has one or several customizable colors, and some of them are animated.

+default color palette.

+The shape is declared as follows in SCSS:

+   :caption: ``/website_airproof/static/src/scss/primary_variables.scss``

+.. image:: shapes/shapes-bg.jpg
+   :alt: Shape colors
+
+The blackish color is used at the top (`c5`), the lightish (`c4`) at the bottom and in between,
+the shape is simply transparent.

+
+**With color palette reference and custom color**
