gwt panel flow panel

i like to design e开发者_高级运维ntire html with GWT.

but when i press ctrl and + then entire html must be zoomed from center not from upper left corner.

then what type of panel should i use?

flow panel , stack panel i dont know.

Any, but your root panel should have a fixed (or minimum) width and be centered. Flowpanels are based on divs, so that's what you probably want.
