I am trying to build a site with underscores . so I followed some instructions from lynda.com where I am subscriber.
in reality I am trying to learn webdesign . I have learned little about CSS HTML PHP.
now I tried some code to achieve a header that looks like this website :
so I tried
and made also a solid border and .sitebranding with 3em but I couldn't get the same nice outlook.
so I thought I use container class ( class="w3-container w3-teal">) I tried to make a div in site.header with this class it didn't work . then I tried flex property to make a div or class is not working either.
I don't understand why I can't make a div or class in site-header or site-branding . is that because site header and site branding are self a class.
how I can solve this problem ?
please look for the website above to understand wat I want to design.
