Way to build web styles outside of app?

I have a a few different apps that run independently but look and feel the same on xojo cloud when they run. Its hard keeping the looking and feel the same because when I change something in one I have to change it in all of the apps. Is there something that I can put in a folder where i can just make the change in one spot and when each app runs it imports the file to get the latest web style? Same with universal modules? Thanks for any ideas.

Have a look at this post, it’s an easy way to use CSS in WebApps:
Be aware that you’ll have to look at the Xojo HTML generated code to define your CSS correctly.

You could use a single CSS file in multiple web apps:

<link href="[your link to the stylesheet.css file]" type="text/css" rel="stylesheet">

Regarding « universal modules » you can make your modules « externals » , but it’s a pity, modules can not be made external when they contain classes which is a real PITA.

I place my standard HTML headers and snippets inside Constants inside an external module.
