I keep complaining to the visual designer about this, I can't figure out why this is so hard to fix. What's really strange is it often looks GREAT in some web browsers nobody would ever use (IE) but in Chrome on Windows the lower case "g" characters are almost unreadable and disappear.
If only somebody knew how to fix this?
How did you detect it was missing < p > tags? Is there a tool the designers could error check against to see this error?
Just opened it up in the inspector in Firefox, no black magic here ;-)
I would definitely look into your font names - it tells me that "Lato-Hairline" is used as: "Lato" and "Lato Regular" is used as: "@font-face:Lato". So perhaps the issue is that Lato-Hairline is the font-weight = 100 and Firefox picks it over the other one, only finds the single font-weight and sticks with it?
Just a guess though, webfonts can be weird. For instance: For Chrome, it can depend on what version you use. Just today I ran into a font rendering bug similar to this one where Chromium versions 37&38 had their font-weights switched so that 300 ended up as 500 and 500 was also picked for "normal". So the bug report "all fonts are bold and it looks terrible" resulted in "CANTFIX old Chrome be weird", basically.
WE'RE WORKING ON IT BRIAN!
