CSS Trick: Turning a background image into a clickable link


One of the things I most often get asked by people trying to master HTML and CSS is “How do I make a background image clickable?” It’s easy to wrap a regular image tag in a link, but what if your design or situation required that you use a background image? It’s actually quite simple. Just follow these steps and I’ll show you how to make a clickable background image like this:

Start with just a link exactly as you would make it for any other purpose, and make sure to give the link an id so that we can use that to apply our styles:
1
<a href="http://problemfacing.blogspot.com/" title="ASP.NET Problem Solution" id="xavisys-logo">ASP.NET Problem Solution</a>
That’s all the (X)HTML you’ll need to make your background image clickable. Your link should look something like this: 
So, how can we make a background image a clickable link? It turns out it can be done with a clever CSS trick. Let’s get started by adding the background image and make the link the same size as the image (so you can see the whole image). Since an anchor tag isn’t a block level element, we need to force it to display as “block” so that we can specify the size:
1
2
3
4
5
6
#xavisys-logo {
    background-image:url(/wp-content/uploads/2009/11/email_logo.gif);
    display:block;
    height:58px;
    width:200px;
}
At this point it should look something like this:problemfacing.blogspot.com
Now all we need to do is hide the text. This can be done using “text-indent” and indenting the text completely off the screen like this:
1
2
3
4
5
6
7
#xavisys-logo {
    background-image:url(/wp-content/uploads/2009/11/email_logo.gif);
    display:block;
    height:58px;
    text-indent:-9999px;
    width:200px;
}
And the finished product looks like this:problemfacing.blogspot.com
And there you have it – a quick CSS trick with clean markup that turns your background images into clickable links. The best thing is, these don’t adversely affect your SEO and can even be easily used inside of header tags if needed!

Tip/Trick: Fix Common SEO Problems Using the URL Rewrite Extension

Search engine optimization (SEO) is important for any publically facing web-site.  A large % of traffic to sites now comes directly from search engines, and improving your site’s search relevancy will lead to more users visiting your site from search engine queries.  This can directly or indirectly increase the money you make through your site. This blog post covers how you can use the free Microsoft  URL Rewrite Extension  to fix a bunch of common SEO problems that your site might have.  It takes less than 15 minutes (and no code changes) to apply 4 simple  URL Rewrite  rules to your site, and in doing so cause search engines to drive more visitors and traffic to your site.  The techniques below work equally well with both ASP.NET Web Forms and ASP.NET MVC based sites.  They also works with all versions of ASP.NET (and even work with non-ASP.NET content).

ASP.NET MVC - Set custom IIdentity or IPrincipal

Here's how I do it. I decided to use IPrincipal instead of IIdentity because it means I don't have to implement both IIdentity and IPrincipal. Create the interface interface ICustomPrincipal : IPrincipal { int UserId { get ; set ; } string FirstName { get ; set ; } string LastName { get ; set ; } } CustomPrincipal public class CustomPrincipal : ICustomPrincipal { public IIdentity Identity { get ; private set ; } public bool IsInRole ( string role ) { return false ; } public CustomPrincipal ( string email ) { this . Identity = new GenericIdentity ( email ); } public int UserId { get ; set ; } public string FirstName { get ; set ; } public string LastName { get ; set ; } } CustomPrincipalSerializeModel - for serializing custom information into userdata field in FormsAuthenticationTicket object. public class CustomPrincipalSerializeMode
