Please can someone take a look at my code and advise how I place the 'helpContainer' just below the red icon that was clicked.

 

Been messing around a lod of other codes from various calendar scripts that i have, but nothing seems to be working for me.

Hi, If you are looking for an elegant style overlay with fading in and out etc, then you might want to look at using jquery to achieve this effect. There are a lot of pre built plugins at your disposal that already do what you need. A good example is on this home page:

 

http://flowplayer.org/tools/demos/overlay/index.html

 

r you can search through the jquery repository:

 

http://plugins.jquery.com/

 

 

to start with the basic will do for the site as i do not want to add in to many javascripts from jquery, i done this before on a site and the whole site was messed up as some of the jquery javascript functions are also names of my own, and the time to change them all was too long, i gave up on this project using jquery and a bit shy to use again.

 

how would i place the box in the center of the viewpoint of the browser using javascript and the ID of the boxes ?
