Here's an example I just found of one the weird ones:
<p style="line-height: 19px; font-size: 16px;"><span style="font-size: 1em; line-height: 1.2;">YouTube videos and a local news station, KITV, helped to spread the word, which resulted in contributions from complete strangers. The <i>One of Our Own</i> team had to invent it themselves. Again, at that time, there were no Kickstarter-like websites available.</span></p>
I have not defined line height and font size in pixels.
???
