Montserrat WEB SAFE google font not rendering properly

I am using web safe google font MONTSERRAT and mapping it at this url,wght@0,100;0,200;0,300;0,400;0,500;0,600;0,700;0,800;0,900;1,100;1,200;1,300;1,400;1,500;1,600;1,700;1,800

The trouble I am having is that upon preview and publishing and viewing the prototype on chrome the font is rendering heavier/more bold than I set the font to be.

RP file:
Montserrat headings.rp (52.3 KB)

Link to published file:

boosting for clarity

quickly pasted the font link in Axure (10) and looked at the generated HTML in the Chrome Dev Tools:


SemiBold seems here to be a font weight 650.
And since the CSS definition has only 500 and 600 it might pick the next larger font weight.
That’s why it might look off.

Hope this helps.

Thank you so much! I will try and update the CSS definition within the mapping.
