Menu
I have my website and it looks great everywhere however I'm not a professional coder for Android. I do not know the extra quirks it has and I'm not sure hoe much I really need to know. Is there a way to single it out like in conditional comments for IE?
Here is my website and the banner and logo appear off to the left hand side of the screen. I have a Samsung Galaxy 3 and this is what my banner looks like on it.
Now I realize why this is happening, it's because they are both absolutely positioned and obviously the margin-left is making it go off screen. However I can't change that without destroying the layout for all the regular desktop browsers.
#site-title { background: url(img/heavensgate-logo.jpg) no-repeat; width: 229px;height: 297px; position: absolute; top: 0px; left: 50%; margin-left: -438px; z-index: 2; border: 0px; text-indent: -9999px; }
#banner { position: absolute; top: 165px; width:868px; left: 50%; margin-left: -448px; z-index: 1; padding: 15px; background-color:
#fff; border: 1px solid #b4b4b4; }
<h1 id="site-title"><span><a href="http://heavensgatewinery.ca/" title="Heavens Gate Winery" rel="home">Heavens Gate Winery</a></span></h1>
<div id="banner">
<img src="http://heavensgatewinery.ca/wp-content/uploads/banner8.jpg" style="position: absolute; visibility: hidden; top: 0px; left: 0px; border: 0px none;">
</div>
I'm confused as to how I should work with getting the banner and logo to work with Android. Any help is appreciated.

Absolute Positioning You can use two values top and left along with the position property to move an HTML element anywhere in the HTML document. Move Left - Use a negative value for left. Move Right - Use a positive value for left. Move Up - Use a negative value for top.
Whereas the position and dimensions of an element with position:absolute are relative to its containing block, the position and dimensions of an element with position:fixed are always relative to the initial containing block. This is normally the viewport: the browser window or the paper's page box.
Adding to Luca's point, here's two posts that test performance of translation vs position objects. TLDR: Using transform: translate(x,y); greatly decreases paint times on elements with CSS transitions. However, position: absolute; top/left will be faster if used on elements without transitions.
When you need to position elements with absolute positioning you should almost always do so inside a relative positioned element.
<div style="position:relative;"><div style="position:absolute;"></div></div>
Although this is not the problem described there, the Android browser has another issue regarding absolute positioning; absolutely positioned DIVs disappear. The solution Paweł Komarnicki found is -webkit-backface-visibility: hidden:
<div style="position: relative">
<div style="position: absolute; -webkit-backface-visibility: hidden">
</div>
</div>
