Browser Startpage put on laptop and phone

I made a couple of very rough and basic example startpages to show what html-codes do. You may also use them as templates and please edit them the way you want for your purposes. Don't be afraid to try thing out.

You have two possibilities: create a link to an extern startpage hosted on an provider or to a local one on your laptop/phone.

EXTERN: Make an external shortcut on your laptop/phone in Firefox browser

Upload your files to your webspace provider and put the url-address of your startpage in the url-address field of your browser and click enter. Then:
for Laptop: in the browser click top right corner on the three stripes, choose 'Settings' / 'Home' click on 'Use Current Page' and close the page. Ready.
for Phone: in the browser click top right corner on the three dots, choose 'Ad to home screen', click 'Add', click again 'Ad'. Ready.

LOCAL: Make a local shortcut on your laptop/phone in Firefox browser

for Laptop: open your new startpage in your browser (eg go in filemanager to your new startpage and dubbelclick), click top right corner on the three stripes, choose 'Settings' / 'Home' click on 'Use Current Page' and close the page. Ready.
for Phone: send your new startpage to your phone, download the file, open with filemanager and then open it with firefox, click top right corner on the three dots, choose 'Ad to home screen', click 'Add', click again 'Ad'. Ready.
