javascript - How do I take the scrollbar into account with viewport width units? -


i trying develop carousel similar netflix, cannot make responsive. have been using codepen example:

link example

in example, has hardcoded width , height. make use responsive measure (percentages). wanted use vw viewport width units, doesn't work me because not exclude scrollbar. so, when want every carousel item have width of 20vw (so each 1 20% of viewport size), wider want because viewport not exclude scrollbar.

how can fix problem?

i have made example: link

in example, want show 5 items , showing arrow on right. 6th item should hidden behind arrow, arrow width not correct.

the width of every item 18.4vw ( (100-8)/5=18.4). can see, have put padding on left , right 4vw(so, subtracting 8 total width), so, have made arrow layer with:

position:absolute; right:0; width:4vw;

in manner, arrow fixed right.

the problem 18.4vw measure respect viewport, , there scrollbar, width not correct, because scrollbar width breaking correct measure.

i dont know if understand want make.

br.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
