CSS CSS Layout Techniques Float Layout Mobile First Layout

this works in Goole, but not in Firefox

Hello!

I have practiced this code and run it on firefox a few times before, but for some reason, this time the columns don't reach the footer section of this code in Firefox; however this code looks perfectly fine in Google. Can you please tell me what I should do to get my columns to reach the foother in Firefox too.

thanks

Add this to your .col style, this worked on my machine:

display: inline-table;

Firefox is apparently more picky when it comes to height attribute :)

Hello,

it totally worked, but how did you figure that out. I didnt have that problem before with Firefox. What does inline-table mean?

thanks

Honestly, I have no idea. It's just one suggestion I found online.

Oh, what did you type to get this answer?

thanks:)
