html - How can I center a right-aligned DIV? -


this question has answer here:

i have div has text right aligned. want center div within parent.

the code below applies right-alignment.

css

.outerdiv {     text-align: center;     width: 100%; }  .innerdiv {     text-align: right;     width: auto; }

html

<div class="outerdiv">     <div class="innerdiv">         10<br/>         <span style="border-bottom: 1px solid black">             + 2         </span><br />         12     </div> </div>

i know can done using margin-left: auto; margin-right: auto in outer div, requires set inner div's width, don't know ahead of time.

ideas?

since you're setting text-align: center on parent element, set display of inner element inline-block. in doing so, inner element centered horizontally due fact has "shrink-to-fit" width based on width of contents:

.outerdiv {    text-align: center;  }  .innerdiv {    display: inline-block;    text-align: right;  }  .innerdiv span {    display: block;    border-bottom: 1px solid black  }
<div class="outerdiv">    <div class="innerdiv">      10<span>+ 2</span>12    </div>  </div>

i removed <br /> elements, , changed display of span element block. replace p element (since it's block-level default).

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; } ...
