Hi Arash Khangaldi,
This is totally dependent upon your design structure.
Let me share my knowledge with you.
1. If you are designing a page using the height and width of any
or with the values in
"pixel" then while the window is adjusted the page and the controls that you have set for your page will try to adjust with the given portion but you have given a fixed length for the page controls. so that will then be distorted.
2. If you are designing the page with the values defined in
"%" then your page controls and the value of the width and height of your controls will be adjusted in "%".
This will not distort your page.
This takes the whole page as 100% and divide the length among themselves.
For better understanding view this link.
{ Difference between em, % and px; }
percentage vs pixels?
Thanks
