How to create new e107 theme from HTML template in e107 2.3. Video serie about porting Oriel Theme
Warning. This is advanced stuff.
Oriel theme is not a bootstrap theme, it is maybe 4 years old (possible jquery issues), so I don't know if it is possible to use it for e107 now. But I have not used the licence and I was able to get permission by the author to use it any way I want.
This is more about porting that about theme itself.
downloaded HTML version
installed e107 2.3 version (from 17.03.2020)
installed JM Core 1.9 plugin and set for K-Admin skin
K-Admin skin set as admin skin
created empty theme folder oriel
prepared starter theme pack
If anything above is not clear to you, ask in comments, it is basic stuff not covered by this topic
PRE-INSTALL THEME STUFF:
copy theme.xml and customize it
Libraries (if needed)
add the theme preview image
copy theme.php and change class name
copy other folders
The standard way in the Theme manager.
Just check the homepage if there is an error. Now porting can start.
NOTE: after time I found that it is easier to start with just home and default layouts. They are already prepared in the starter part, so no mention of layouts in the preparation phase.
