You may or may not know this, but you can do limited HTML markup in comments on blogs that run on the Blogger software (*.blogspot.com websites).
I will occasionally use <i> </i> tags (you can use lower-case or upper-case i's, it doesn't matter) to italicize text in a comment. I like to do this to another person's text that I am responding to, so it's clear the text wasn't written by me.
Example:
What I type:<i>Hey, how's it going, Splotchy?</i>
Fine, thanks for asking!
The text above gets displayed in the comment as:Hey, how's it going, Splotchy?Fine, thanks for asking!
Well, I noticed when I tried to italicize some text in a comment earlier this week that things are a little different. When I previewed the comment it looked fine, but when I actually published the thing there were no line breaks.
Instead, the comment appeared like this:Hey, how's it going, Splotchy?Fine, thanks for asking!
Icky, eh?
Previously, Blogger was converting my line breaks into HTML line breaks, which are represented by the <BR/> tag. Now, it appears that they have modified their software. If Blogger now sees an HTML tag included in a comment, it no longer converts line breaks to the <BR/> tags recognized by browsers.
A little sidenote for those who want to know. A line break in an HTML source file does not equal a line break in a browser. Blogger does the heavy lifting of converting the line breaks that you make in your blog posts to HTML line breaks (<BR/> -- case doesn't matter here -- it could just as well be <br/>).
So, you have the option of giving up your use of italics in comments, or you can be a little amateur HTML coder and add a <BR/> to force a line break yourself.
Here's an example how to do it:What I type:<i>Hey, how's it going, Splotchy?</i>
<BR/><BR/>
Fine, thanks for asking!
Which will display in a comment as:Hey, how's it going, Splotchy?Fine, thanks for asking!
Anyways, I'm a geek. Happy commenting! Feel free to give this a try on this post, you nice people, you.
Try it with and without the <BR/> tags if'n you don't believe me.
