javascript - Inherit colour and then make it darker/brighter -


i have 2 div's 1 .father , other 1 .child - follows:

<div class="father">   <p></p> </div>  <div class="child">   <p></p> </div>

as can see, child not inside father (sorry if seems doggy, example blinked me). trying do; when give .father background colour lets "background-color: #000". want child inherit colour black make brighter/darker...

i have tried following: 

.child {   background-color: -20%; }

i don't know if real way, guess it's stupid - need share did. have tried using css transparency applied whole div... if div has text inside it?

so example, wrap div .child div , give div black background, apply transparency div .child - apply transparency text well!

if have added around how can make span inherit colour of div inside it? , inherit size well.

i'm afraid cannot in pure css. unless of course work rgba colors make transparent.

there function in sass (and less) allows darken/lighten colors. take @ these function's reference here. more information sass/scss: http://sass-lang.com/

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; } ...
