I got fed up with not having full pixel control of vertical whitespace so I looked again for a solution.
This seems especially difficult in Lotus Notes designer, i used to put small font and returns in but this is a horrible fudge.
Here is what i came up with:
After an Iframe you don't need a <br>, but after text or an image you need a <br> , then put:
<img vspace=2 height=1 width=1 src='wdot.jpg'><br>
Change vspace to whatever you need, it seems you need to put height=1 and width=1 else some browsers ignore the vspace bit.
Some sort of src is needed, and if src="" or src='' in the code some browsers also ignore it all.
You do not need to put in an actual image, it works the same as a broken image, this would slow the page down from loading, probably best to put in an actual image but ...
This seems fine on Internet Explorer 6 and Firefox 1.07
NB I got adapted this idea from: http://www.dsiegel.com/tips/wonk7/vertical.html Thanks!
