Solution 1

For starters, you don't even have a button element in your html, so it is of no surprise to me that you are not seeing the behavior you expect. You may need to clarify/update your question if you with to get a better answer.
If you are trying to resize an asp:Button or input control, just use a percentage (i.e. '50%') for the width attribute and it will automatically resize when your page does.

I am using span in link.

If you are referring to your span in the link in your pagewrap div, then it may be that your issue arises from your text not being placed in between the span open/close tags, but that is secondary. You can always add a "width: 50%" attribute into the style tag for the anchor element. That will do the same as what I was explaining above.
