I just want to know what the width (in pixels) of the "Welcome to ILance 3.1.4" table is here: http://demo.ilance.com/. I need to make an image the same width, but I don't know how to figure out what it is. Any help would be appreciated. Bonus points for telling me how to do it .
On my pc, the dimensions (pixels) are, 547 x 31. To make an image that size you will need a piece of image editing software, i.e. photoshop or fireworks. If you are looking for something free try "The Gimp", then simply depending on what you want the image to contain, draw it. Then you will need to save it in an appropriate format, (png, gif, jpg).
You should get the web developer add-on for firefox it tells you all sorts of infomation about webpages like CSS info
