Problems with responsive design?

Question

css

Started building a website using Adobe Muse. On a computer, the site is well displayed and rubbery, but if the resolution of the browser window is 700px wide and move the scroll line to the right, then there will be such garbage as in the photo
And here is how it is displayed in the full window and on the phone

Answer 1

rather overflow: hidden; allowed, you need to show the code, not the pictures, preferably a worker where the thread is on the hosting

Answer 2

maybe max-width: 700px is written somewhere

Answer 3

I advise you to do such things on the bootstrap ... and it will be more beautiful and less clumsy ... just look at a couple of lessons and follow. the day can already be quite tolerably typeset.
