i really don’t how to use CSS to customize a theme.
i choose the Argent theme and when i active this one his does not appear like his appear in the demo.
i can see the top bar with home, blog, portfolio … and the 3 pictures under the text presentation how i can i do ?
Also if somebody speak french it could be easier but if not i will dot it by myself for understanding
Have a look at the set-up instructions on the Argent theme page to get you started. You shouldn’t need CSS to get your site looking like the demo one. If you get stuck in English try asking in the French language forums.
