Can't get the resolution right with my game when exported to HTML5 and other issues

I am exporting a game to HTML5, but I can't get the .html file to load so that the browser window doesn't move when I use the cursors to select options in a menu. Like in a Flash application whose window is independent of that of the browser's window.

Also, I can't reduce the resolution so that the game is running in a small window, in HTML5. In Flash it is straight foreward but not when exporting to HTML5. It uses always the normal scale/resolution of the objects.

I'm attaching a file as an example.

I have quite figured out how to avoid the up/down arrows scrolling the window either.

Here seems to be a solution but I don't know where in the .html file to put these codes. :(

The other issue is how can I reduce the resolution. It seems that it is always the same, only thing that changes is the canvas size..
