html - CSS: Making nested min-height consistent -


for reason, nested elements min-height not inherit height of grandparent in browsers.

<html style="height: 100%">     <body style="min-height: 100%">         <div style="min-height: 100%; background: #ccc">             <p>hello world</p>         </div>     </body> </html>

i haven't bothered testing between different browser versions, in chrome 26 , opera 12.14, displays expect, gray background covering of screen hello world in top left corner.

however, in ie 9 , firefox 20, gray background height of single line of text.
testing further, adding:

position: relative div changes nothing
min-height: inherit on div changes nothing
position: absolute changes width, height 100% in above browsers except ie 9, background covers text.
position: fixed similar position: absolute, except ie 9 reverts original behaviour of 100% width.
float: left similar position: absolute, except firefox 20 shrinks background cover text.

from http://www.w3.org/tr/css2/visudet.html#the-height-property:

if height of containing block not specified explicitly (i.e., depends on content height), , element not absolutely positioned, value computes 'auto'

is min-height considered explicit or not? think confusion between browsers. position: absolute, fixes firefox, , ie 9 has unexpected behaviour (which not unexpected, being ie).

is possible consistent across major browsers?

please not suggest answers require javascript, or body having fixed height. know possible workarounds, isn't i'm trying achieve. using position: absolute breaks layout pulls element out of flow, , positioning below dynamically sized element, workaround javascript.

firstly, observation:

in chrome 26 , opera 12.14, displays expect, gray background covering of screen hello world in top left corner.

does seem incorrect, in chrome version 26 shows gray background height of single line of text. (just firefox , ie9). believe right according w3 spec quoting from, height of body containing div not specified explicitly.

you can display: table, display: table-row , display: table-cell. won't need min-height @ then. have tested jsfiddle in chrome 26, safari 5.1.7, firefox 20, ie10, ie10 in ie9 mode, ie10 in ie8 mode , renders same in of these browsers, starts break when using ie10 in ie7 mode.

css

html {   display: table;   height: 100%;   width: 100%; } body {   display: table-row; } div {   display: table-cell;   background: #ccc; }

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
