Problem with Line spacing using Styles

[Bluesman]

Hi Pablo or else. Started to play arround a little with a hobby project.
I am using a webfont "Exo Extra Light" which I setted up in "@font-face fonts". Using it in Styles "Heading 1 <h1>". I have 4 different breakpoints in the project which I also setted in th Style; Default 1460, 1024, 768, 480, 340. Different size for the font in each breakpoint and the Line spacing set to: 1.0 in each. This have worked before

The url for the site is: https://www.america-libre.com/index.php

You can see the real difference between the line spacing when chrinking down the browser window to breakp 480. This worked on other projects I've done in older versions of WWB? I have tryed to finetune the Line spacing for each breakpoint, but even using (0.5) in the 480 and 340 breakpoint makes no difference?? Something I missing? I have read the help and info about the responsive text one more time to check but can't find a reason.
Hope I can get some understanding to this... Gracias

By the way... the "emoticons" for the Forum is corrupted for me like

Did you enable 'include line-height' in the text properties?

Ok, thanks Pablo, did that and now works as it should... thought settings in the object properties would interfear with the responsive functions... but still learning... thanks.
