i build widget website , add css dynamically on loading problem conflicting host website css file . following code widget has css file attached on loading :

function main() {     jquery(document).ready(function($) {     /******* load css *******/     var css_link = $("<link>", {              rel: "stylesheet",              type: "text/css",              href: "http://example.com/widget/green.css"         });         css_link.appendto('head');         var txt;         txt='<div id="wrapper">';         txt=txt+'<ul class="tabs">';         txt=txt+'<li id="fixtures_tab"><a href="#fixtures">hepsi</a></li>';         txt=txt+'<li id="live_tab"><a href="#live">canlı</a></li>';         txt=txt+'<li id="finished_tab"><a href="#finished">bitmiş</a></li>';         txt=txt+'<li id="program_tab"><a href="#program">başlamamış</a></li>';         txt=txt+'<li id="postpond_tab"><a href="#postpond">ertelenen</a></li>';         txt=txt+'<li id="selected_tab"><a id="f" href="#fav">oyunlarım (0)</a></li>';         txt=txt+'</ul>';         txt=txt+'<div class="tab-container">';         txt=txt+'<div id="fixtures" class="tab-content"><script type="text/javascript">get_all_today_matches();</script></div>';         txt=txt+'<div id="live" class="tab-content"><script type="text/javascript"></script></div>';         txt=txt+'<div id="finished" class="tab-content"><script type="text/javascript"></script></div>';         txt=txt+'<div id="program" class="tab-content"><script type="text/javascript"></script></div>';         txt=txt+'<div id="postpond" class="tab-content"><script type="text/javascript"></script></div>';         txt=txt+'<div id="fav" class="tab-content"><script type="text/javascript"></script></div>';         txt=txt+'</div>';         txt=txt+'</div>';         $('#widget-container').html(txt);     }); }

i want know there way isolate widget's css ??

by way main function called anonymous function (for isolation purpose)

ps: used css reset still same problem .

you can namespace of css. avoid having issues common css class names container or wrapper, example:

.my-amazing-widget--tab-container {     height: 100px; }

if of css namespaced above, not website have widget name in css.

i avoid using declarations !important user suggested in comments—it possible if override common class styles end negatively affecting website's styles.

i avoid global declarations importing css reset widget. css resets override elements body, div, etc. can negatively affect host website's css.

you need update related html use namespace. css namespacing best approach problem , best practice when developing widgets embedded in other websites , applications.

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!
