No. Not based on this information, which is less than nothing.
When I compose my post in HTML tab, things are fine. But when I go back to HTML after I hit Visual tab, there are lots of <div>s and <span>s inserted uninvited, automatically. Even repeated delete won’t keep them coming back, away from my posts and pages. The problem is those <div>s cause problem on my site (I use “Paalam” a two-column Theme ): when there are too many of them, my two-col becomes 1-col, the narrower left side col would go to the bottom of the wider right side.
Thanks.
