Sometimes it is necessary to control the vertical spacing in your WordPress blogs, especially around inserted pictures. In the WordPress editor go to the Text (HTML) editor and insert this command:
<div style=”margin-bottom:3em;”><span style=”display:none;”> </span></div>
You can control the vertical space by changing “3em” to “5em”, “10em”, etc.
Make sure your system does not change straight quotes ” to curly quotes “ or ”. If so just replace with straight quotes.
