Plate-Variables describe how the LESS Variables in the CONFIG tab are constructed. It creates placeholder content about how the variables work as well as the type of variables you have access to.
There are a few default variables in each template (there is no limit to how many you can add). The four default variables are dropdown, color, text, and image. These variables help get you started and stay consistent when creating your site.
Dropdown are used to give the user a preset of options. This is helpful for things such as font weight and background position.
Color variables help you keep a reference to the colors used on your site. This is helpful for keeping a consistent color palette throughout your site.
Text variables controls the options for styling related to text. An example would be the visited color for links and setting the curvature for borders.
Image variables are default images that come with the template.
Font-picker is used to select font styling.
Font-weight specifies the weight or boldness of the font.
