Hi
Thanks for looking at the code, yes it does work both on a full size screen and in the mobile preview. I did as mnakalay suggested, but I am not a programmer and I must admit that a got a little confused trying to understand the Bootstrap 5 documentation.
The error message that disappeared very quickly, seems to have been a one off, I do not get any error messages now. However, as I said I am not a “pro” - the last time I did a website was in 2013, to say that things have moved on since then, is a bit of an understatement !
After a couple of months of “playing about” on my local computer I am just becoming to understand how complex the system is. I am worried that, because I don’t understand the big picture, I might do something that might appear to work in isolation, but does something else somewhere in the system which might cause problems.
I have now set up Concrete cms on our web hosing company and I am starting to populate the site. We have 2 languages with about 350 pages per language, so it is lot of work just to populate (and translate) so I would hate to compromise all that work by doing something stupid on the programming side that I don’t fully understand.
I will keeping playing with my test set up I have locally on my computer, and I may use this 3 column code later on our production site - if I feel confident enough.
It would be nice if there was a section in the documentation that goes into greater depth on creating these page template files. In the backend there a number page templates that are shown in image form but there is no associated file.
Again thanks to both of you for help.
