I have some doubts about positioning of an element in the web page. The example goes like this: I have a table of 20 rows 3 columns. In the third column of some rows(3rd, 10th, 18th for example) an icon is appearing. On hovering over the icon I have to show a dialog DIV which contains little more detailed information of that respective row.
So to accomplish this, how shall I find out the dynamic positioning of that icon in different rows of the table and then hovering over the icon I should be able to dynamically position the DIV container just beside the icon.
