Template SVG Logos

Cassioepeia Logo

The default Joomla 4 site template, Cassiopeia, uses the word CASSIOPEIA as a Brand Logo. It appears at the top of every page unless you set Brand to No in the Templates: Edit Style form, Advanced tab, or you use a Title word instead of a graphic. That word is actually a Scaled Vector Graphic (SVG) file. You can choose an alternative graphic but it is quite tricky to create and use an alternative SVG Logo. This brief set of instructions may help.


Inkscape is an open source, cross platform vector graphics application, meaning you can download it for free and use it on Linux, Mac or Windows. So to get started go to the Inkscape website and download the version for your laptop or desktop computer. Start Inkscape and you are ready to create an SVG Brand Logo. The screenshot below shows Inkscape part way through creation of a new SVG Logo.
