Integrate CSS JS

Hi Guys, i need your help for integration of a css file and a js file. It is a modal popup for a disclaimer to visit the website. So, now i have two files. What i have to do now? Everything i tried was not working :-/
Thank you for your help.

Hi @RME

Go from top menu: Page >> Settings
And add the files in the Header File Attachments

Preview mode doesn’t work for .js files.
You must preview in web browser.

Ok. it doesn’t work. I ll check the code again. Thanks for your help.

Sometimes when I’ve added some code, css and js things have behaved very strange.
It’s when the new code/files uses the class “container” (or other class that Blocs use).
Then you’ll have to edit your added code, css and js to use another class name.
