Do I understand correctly: You are „about ready“, and didn’t check up to now, if it is responsive? hmm …
Is yours site set up as „responsive“?
Is your breakpoint/are your breakpoints set up as „responsive“?
You may correct this „on the fly“, but don’t be astonished, if you layout look like scrambled eggs afterwards.
Yes,it's set up as " responsive" .. but it not works
What doesn’t work?
Please give us one clear example with a screenshot like „this rectangle doen’t resize.".
Please make sure that (a) this element is activated and (b) the screenshot shows all parameters of the upper control strip and the breakpoint bar. Additionally make sure, that all guidelines and frame borders are set to „visible“.
