Create a Lightbox effect only with CSS – no javascript needed

You may call it Lightbox, or Greybox, or Thickbox, but it’s always the same effect.
When you are on a page, and click on a photo or trig some event, a Lightbox is an effect that fades the pagein the background to show you new content in the foreground.
I mean this effect

In the upper example, when clicking on a photo the site fades to black and shows the photo, in the lower one when clicking on “login” the site fades to white and shows the login form.
There are tons of Lightbox scripts in the web, each one with its unique features and limitations, but all require massive use of Javascript or the installation of javascript frameworks.
In some cases, there are “lightweight” versions with “only” 40KB of Javascript.
This example does not want to compete with those scripts, but if you are looking for a simple, 100% CSS, 0% javascript lightbox, this may help you.

IP Address Geolocation XML API

The API returns the location of an IP address (country, region, city, zipcode, latitude, longitude) and the associated timezone in XML format. You can find below code samples with PHP, Javascript, Ruby, Python and ASP.

Usage

For city precision, do a query with the following API (if you omit the IP parameter it will check with your own IP) :

http://api.ipinfodb.com/v3/ip-city/?key=&ip=74.125.45.100

For country precision (faster), do a query with the following API :

http://api.ipinfodb.com/v3/ip-country/?key=&ip=74.125.45.100

If you don’t have an API key yet, just go to here and register for your free API key. You will need this API key to be able to use our newer APIs.
