How to make a div fill a remaining horizontal space?
(26 answers)
Closed 4 years ago.
I have two divs side by side.
Div1 width is 200px
and Div2 should fill the screen.
To do this, I use jQuery and detect the screen with and then substuct 200 from it.
But if I use this way, jQuery slows down the browser.
So I'm searching a better way rather than using jQuery.
What is the best way to do this?
Update :
I forgot to write that float did not fixed my solution.
Thank you I'm going to check the answers.
