PROBLEM: I want the grid to appear in the center. How do I do it? SOULTION
You can try to put a <CENTER></CENTER> tag around the IFRAME code.
For example if your grid code is something like:
<iframe width="1000" height="1000" frameborder=0 marginwidth=0 marginheight=0 VSPACE=0 HSPACE=0 SCROLLING=no src="https://milliondollarscript.com/display_map.php?BID=1"></iframe>
Then you can center it like this:
<CENTER>
<iframe width="1000" height="1000" frameborder=0 marginwidth=0 marginheight=0 VSPACE=0 HSPACE=0 SCROLLING=no src="https://milliondollarscript.com/display_map.php?BID=1"></iframe>
</CENTER>
