marquee：从托管在云端硬盘上的txt文件中获取文本

I'm searching for an easy way to update a simple marquee on an HTML5 web page (e.g. displaying "we're on vacation from...") not via hard coding on the page itself but via an external txt file to be read. The thing is the text file should be hosted on a common cloud drive like Google drive or OneDrive. I make the file publicly available and include the public link to the txt file in the website code. Then I should be able to adapt the txt file in the cloud drive and see my edits in the marquee on the page. Please support. Do you have other, better ideas? thxI'm searching for an easy way to update a simpl
