Wappler provides a weight selector, that selected weight is also shown in the prev screenshot, so i assumed that it will also be honoured.
also, weight selected for BODY was honoured, ref:
workaround is rather simple - adding a separate entry in style.CSS (any custom CSS file) to overwrite the weight. or manually change the bootstrap CSS file from outside of Wappler (but it will get overwritten next time you use theme manager).
i think this is not the intended function - chosen weight must have been updated in the bootstrap CSS for Headings.
Theme Manager is not updating the bootstrap.min.css file for h1, h2, etc. tags with the correct font weight. It always updates with 500 irrespective of what is selected in the theme manager ui.
I manually changed it to 600 in the CSS file - browser honours that and can see the font getting bold.
Theme manager needs to fix how it updates the bootstrap.min.css file or change how it informs the bootstrap system about this update of the font weight. Coz the CSS file is not properly updated when changes made from theme manager.
Could the problem be because the font you've selected is a variable font? I don't think Wappler supports variable fonts, which is a great pity. Variable fonts have cropped up in a few threads, but I think there could be some confusion about whether or not they have been implemented - eg in this thread:
I realise you were trying with this (variable) font. The UI doesn’t differentiate between standard and variable fonts. In the case of variable fonts, I wouldn’t have thought it makes sense to choose the weight - as you have to, using the Theme Manager.
