Hi there, Please read media query css and apply on your site
https://www.w3schools.com/css/css_rwd_mediaqueries.asp
So you want the menu to appear when this section is in view but not when others are in view? AFAIK it cannot be done with CSS alone, you need some JavaScript to detect when the section is in view or not, then alter the CSS display: property to make it appear or disappear. For example: https://codepen.io/bfintal/pen/Ejvgrp

I don’t know a lot about javascript but i will try and let you know.
