Center Align an Image

The easiest way to centre align an image in html is to wrap the <img> tag inside a <div> tag and text-align to center.

<!-- html elems -->
<div class="wrapper-img">
    <img src="images/pic.png">
</div>

/* css */
.wrapper-img {
    text-align: center;
}

JQM: Fix PhoneGap Android textarea Jumping Around

Android 2.3 browser is buggy when it comes to CSS3 properties. Recently we got this
weird bug when user types something in a textarea component. The page jumps around with
each character we typed.
We can fix that by not using any CSS3 3D properties like -webkit-transform: translate3d(0, 0, 0);.
Also, in the AndroidManifest.xml file add windowSoftInputMode="adjustPan" in the activity tag.

<activity
    android:name=".ProjectNameActivity"
    android:configChanges="orientation|keyboardHidden"
    android:windowSoftInputMode="adjustPan"
    android:label="@string/app_name">
