In the product interface, each topic has its own corresponding icon:
You can work with your designer to create these icons. Please see below some design notes from our Lead Designer and arrange a meeting to discuss:
"We create our Topic icons in adobe illustrator. In our current platform style, we try to communicate the meaning of the topic with the most simple geometric shapes possible.
We always draw it within a 44px * 44px square template. The image does not necessarily have to reach to the edge but the image is usually centred within the square. The lines should always leave at least a 1px space from the edge.
The line strokes are 1px thick however sometimes they can be 2px if one line needs to be emphasised over another for example within a graph. Dotted lines can also be used.
The colour is always #a1a1a1 as the strand colour is added later to the SVG with CSS styling by our front-end team."
Attached are a few sample illustrator files, any of which can be used as a template.
You then send us the illustrator file and we can export them as an SVG file ready to be placed on the site by our technical team.
