Google Font "Light"

I have been using Google web fonts in a number of application. Special thanks to @Michel Bujardet for his details in this thread: https://forum.xojo.com/10243-google-fonts

(Seems like I forget to express thanks enough to those that help me. So thanks again MB!)

I am using Google Open Sans and I have plugged the following into my app.HTML header;

[code]

.OpenSans { font-family: 'Open Sans', sans-serif; } [/code]

The font comes in a number of flavors: Light, Regular, SemiBold …etc

My code displays the Regular. How do I get the Light?

300 is light
400 is regular
