Font header losing format

when I rewrite the text of the article it loses the font format

and I can't find the article or module with the text "TURN KEY BUILDING SOLUTIONS"

Hello,

You can change the "TURN KEY BUILDING SOLUTIONS" heading in Extensions > Templates > Hot Architecture > Layout > Row Settings (click button next to appropriate row). In the pop-up window, you can change the heading and subheading.

Some WYSIWYG editors can break layout. It's recommended to either configure your editor and prevent it to modify HTML code or to edit the text in HTML mode, without editor.

Thanks,
Milos
