Use of development tools (firefox)
Currently when I am using the development tools are shown the .css files from the t3-assets folder. How to locate the lines in the template.css file?
't3-assets' holds temporary compressed css files when you enable the Optimize CSS / JS option in template settings.
You can disable this option and see the correct file path.
But if you want to customize template css, I recommend to use the 'custom.css' file as we mention here: http://www.t3-framework.org/documentation/bs3-customization#custom-css
Thanks Saguaros, it's OK :-) :-)
