What is the difference between fluid and responsive layouts?

Question

Layout

I was puzzled by the convenience of displaying my ancient shop on mobile devices , which is laid out on tables with a rigidly specified width. Table width=880, you get the idea...
Googling, I was puzzled - fluid layout (which was once the peak of skill) has sunk into oblivion, and the entire Internet is teeming with the phrases "adaptive layout" and bootstrap.
What do you advise? Is bootstrap that good or is it enough to rewrite table width=880 to div width=100%? I don't want to make any special version for mobile - I just need the content to "squeeze" on mobile to the screen.
PS Bootstrap just has css code from hell, is this legal at all?

Answer 1

fluid layout is not popular just because it is difficult to adapt. you need to write a bunch of media breakpoints simply because "at this moment this block went wrong".
bootstrap is a framework with a bunch of stuff. but that doesn't mean you need them all. it is well customizable through scss sources. You can only take what you need from there. then the size of the original css will be small.

Answer 2

no one forbids the combination of "adaptive + rubber". And besides Bootstrap, there are a bunch of other CSS frameworks, including lightweight ones, in which there is almost nothing besides the grid. As an option Skeleton, PureCSS, Milligram.
