Implement CSS in Web Project

That is exactly what I was suggesting. Under normal circumstances I would tend to put such files in Resources, but since HTMLHeader has to be filled at design time, that is probably the simplest.

Hi i just try similar thing again and do the copy file in mojave. still don’t know how to the external css. i try the both with the …/ and without for the ACMSWeb.css

Did you see this thread: https://forum.xojo.com/23367-tutorial-using-css-in-webapps-to-make-your-webapp-more-beautifu ?

yes i read up on the post and manage to do it when i put the follow code on the App.HTMLHeader after setting up the MAMP and put the css in the WEStyle in my Apache htdocs folder

<link href="http://127.0.0.1:8080/WEStyle/stylesheet.css" type="text/css" rel="stylesheet" media="all">

i was using empty style1 and style2 in the IDE and in my css, set the style1 and style2 to something with border and color

does not work if i use the following thought

<link href="stylesheet.css" type="text/css" rel="stylesheet" media="all">
or 
<link href="../stylesheet.css" type="text/css" rel="stylesheet" media="all">
