<h3>Internet Explorer 8 and box-sizing</h3>

<p>IE8 does not fully support <code>box-sizing: border-box;</code> when combined with <code>min-width</code>, <code>max-width</code>, <code>min-height</code>, or <code>max-height</code>. For that reason, as of v3.0.1, we no longer use <code>max-width</code> on <code>.container</code>s.</p>

<p>As of Safari v6.1 for OS X and Safari for iOS v7.0.1, Safari's rendering engine has some trouble with the number of decimal places used in our <code>.col-*-1</code> grid classes. So if you have 12 individual grid columns, you'll notice that they come up short compared to other rows of columns. We can't do much here (<a href="https://github.com/twbs/bootstrap/issues/9282">see #9282</a>) but you do have some options:</p>

<h3 id="mobile-modals">Modals, navbars, and mobile devices</h3>
<h3 id="support-fixed-position-keyboards">Modals, navbars, and virtual keyboards</h3>
<h4>Overflow and scrolling</h4>
<p>Support for <code>overflow: hidden</code> on the <code>&lt;body&gt;</code> element is quite limited in iOS and Android. To that end, when you scroll past the top or bottom of a modal in either of those devices' browsers, the <code>&lt;body&gt;</code> content will begin to scroll.</p>
<h4>Virtual keyboards</h4>
<p>Also, note that if you're using inputs in your modal or navbar, iOS has a rendering bug that doesn't update the position of fixed elements when the virtual keyboard is triggered. A few workarounds for this include transforming your elements to <code>position: absolute</code> or invoking a timer on focus to try to correct the positioning manually. This is not handled by Bootstrap, so it is up to you to decide which solution is best for your application.</p>
<h3 id="browser-zoom">Browser zooming</h3>
<h3 id="support-browser-zoom">Browser zooming</h3>
<p>Page zooming inevitably presents rendering artifacts in some components, both in Bootstrap and the rest of the web. Depending on the issue, we may be able to fix it (search first and then open an issue if need be). However, we tend to ignore these as they often have no direct solution other than hacky workarounds.</p>
<h3 id="support-android-stock-browser">Android stock browser</h3>
<p>Out of the box, Android 4.1 (and even some newer releases apparently) ship with the Browser app as the default web browser of choice (as opposed to Chrome). Unfortunately, the Browser app has lots of bugs and inconsistencies with CSS in general.</p>
<h4>Select menus</h4>
<p>On <code>&lt;select&gt;</code> elements, the Android stock browser will not display the side controls if there is a <code>border-radius</code> and/or <code>border</code> applied. Use the snippet of code below to remove the offending CSS and render the <code>&lt;select&gt;</code> as an unstyled element on the Android stock broswer. The useragent sniffing avoids interfernece with Chrome, Safari, and Mozilla browsers.</p>
{% highlight html %}
<script>
var nua = navigator.userAgent;
var is_android = ((nua.indexOf('Mozilla/5.0') > -1 && nua.indexOf('Android ') > -1 && nua.indexOf('AppleWebKit') > -1) && !(nua.indexOf('Chrome') > -1));
if(is_android) {
$('select.form-control').removeClass('form-control').css('width', '100%');
}
