c# - Calculate area of HTML element on website? -


i'm trying figure out if it's possible calculate area of html element on website? in pixels, percentage or whatever.

my first thoughts have been make assumption element 100% in width , height, , try retrieve size through mapping between html , css.

so if there's width/height attribute in referenced css-file possibly body element covered column takes 25% of area (everything based on screen resolution of course - , i'm still trying figure out how i'd able programmatically).

or whether should render website , calculations based on image common screen resolution @ time).

are there more possible solutions?

(currently i'm trying solve in perl, suppose language that's got library purpose appreciated know about!)

edit: need retrieve visual area every single element on page. example; if there elements on top of <body> element, covers visually, want exclude area <body>'s , on. simple raytracing find visible area every element on page.

edit: let's exclude javascript - other approaches possible?

personally, use jquery - if don't use library, best bet javascript solution.

var $elt = $('#some-element-id'),     height = $elt.height(),     width = $elt.width(),     area = height * width; // contains area in px^2

http://api.jquery.com/height , http://api.jquery.com/width
