I want to create 3 Div tags Dynamically when I press 3 different buttons (Red Green Blue).. When I press Red I want the height of 'red' div to be the size of my screen so that whole page appears to be red and when I press Green I want the height of the 'red' div to bee 50% of my screen and other 50% of the screen should be occupied by other div (which is Green)..
And finally when I press Blue button I want All the divs to appear on screen with equal height...
I'm able to create the divs but I can't delete the previously created div when I press Red button after pressing all three buttons...
Here is the code:

- how are you calculating heights for your three divs – defau1t Commented Nov 10, 2012 at 10:27
- if I were you i'd read answers.oreilly./topic/… before worrying about divs and sizes – lostsource Commented Nov 10, 2012 at 10:29
- WOW!! People are already rating my question -4 ! What's my fault?? The only problem I'm facing right now is even after using "element.removeChild(child); it is not being deleted....... This made me ask a question here... My mistake.. – Nayeem Junaid Commented Nov 10, 2012 at 10:45
- @NayeemJunaid: because the way you have pasted your code was in really bad shape. – defau1t Commented Nov 10, 2012 at 10:55
- @defau1t I always face problem pasting the code over here.. Why can't it be simple like other sites to paste some code in quotess?? – Nayeem Junaid Commented Nov 12, 2012 at 8:50

Reset to default 4 document.createElement("div");
will create a div dynamiclly
var oldChild = element.removeChild(child);
element.removeChild(child);
Removes a child node from the DOM. Returns removed node.
