I'm trying to vertically and horizontally center content of an unknown height in a UIWebView.
What I have right now works great in Safari:
However, it does not look right when presented in a UIWebView:
Any ideas how to get this to work? One thing I cannot do is set the viewport meta, because this needs to work when presenting the UIWebView in a modal view controller on iPad, where it is not the full width of the screen:
<meta name="viewport" content="width=device-width;initial-scale=1.0;maximum-scale=1.0;"/>

I tried your example and it works fine in an UIWebView. I don't know how you load your HTML / CSS. Are you sure that the CSS is loaded correctly? Have you set the frame of your UIWebView?
Here is the code that works for me. I set the frame of the UIWeb smaller than the screen size because you mentioned presenting it modally.
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *htmlString = @"<html><head><style type='text/css'>html,body {margin: 0;padding: 0;width: 100%;height: 100%;}html {display: table;}body {display: table-cell;vertical-align: middle;padding: 20px;text-align: center;-webkit-text-size-adjust: none;}</style></head><body><p><strong>Title</strong></p><p>A long explanation about what's going on and all that.</p><p><a href='#'>A link</a></p></body></html>";
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10.0, 10.0, 300.0, 400.0)];
[self.view addSubview:webView];
[webView loadHTMLString:htmlString baseURL:nil];
[webView release];
}
