transform - Is it possible to "snap to pixel" after a CSS translate? -


i created modal box , vertically centred using technique chris coyer mentioned. problem i've found far box offset half pixel, can make of children little wonky. question is,: possible snap result nearest whole pixel?

update

here couple of pictures better illustrate issue. in first image, can see text inputs , link underlines have rendered correctly:

modal box crisp lines

the second image shows effect after css transforms have been used. notice blur of link underline , incorrectly rendered text inputs.

enter image description here

although second image doesn't show it, notice top , bottom white lines wit same blurred effect.

for record, text inputs styled using simple borders , background colour. i've included css inputs here can see there's nothing special happening:

input {     background-color: #ffffff;     border: 1px solid #cccccc;     border-radius: 0;     box-shadow: 0 1px 3px -1px #d5d5d5 inset;     color: #4c4c4c;     display: inline-block;     font-family: arial,helvetica,sans-serif;     font-size: 12px;     max-width: 100%;     padding: 5px;     transition: border-color 0.1s ease 0s; }

the bulletproof solution ensure element occupies even number of pixels. if height (or width) not divisible 2, attempt render element on half-pixel, causing blurriness.

firefox doesn't have issue because supports true subpixel rendering. so, though element on half-pixel, firefox handles elegantly.

in experience, webkit typically snaps elements nearest pixel –– (for instance, when using letter-spacing property) -- it's kinda strange doesn't behave same way translate.

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!
