Obviously you havent tried to change the size of the map, it still says "width="600" height="350"", which is much, much too large for that small space.

Try this:

Inger,

When I compare the view from design and the browser there are strange differents and that I not what I want.
So in the IDE of the site designer, I establish that it is in the browser not match.
Is there a solution to think of, because I want the display on all the screens to how I have designed the site designer v2.5.
The button is not at the same height as the second column in the browser in desktop and tablet view, and mobile view I have too much white space between my button and the second column.

Is there a solution for this because I know there are a total gene or is it just the program.
Here are the screenshots of what I mean with the problem

With kind regards
Stephane

Your comparisons between the view in RSD2.5 and the browsers are wrong. The browsers are showing the map, RSD is not. The map has, according to the code I posted above here, 260px height, so you will have to add that many pixels to the form.

Inger,

What do you main:

is that height for the class form : 260px?

No, that is not what I mean. I'm saying that the height of the iframe (class .map) is set to 260px. So the element with the blue background will be 260px higher in a browser, where the map is being displayed, than what you see in SD (well, possibly you need to subtract the height of the iframe with nothing in it, some 30-40px maybe).
In other words, all the screenshots of what you see in SD are incorrect.
