After more investigations and a lot of readings on internet to understand how it works... I think there is a problem with CSS rules. SU Make 2017 cannot 'read' them. I don't know I can say it in this way (I don't have coding skills and Im a french speaker).
If SU Make 2017 was able to use Chrome for embedded browser I think it will work.

@Rich-O-Brien
I understand.
I don't have network everytime Im using sketchup why I prefer a local software.
You don't have to fix it. I suppose users like me on SU Make represent a little percentage.
Thank you for your interest on my issue !

@Rich-O-Brien @TIG
Thanks for your responses.
There are errors on Dev Tools Console :

Hi,

I don't know if it is the right place to post.
I am under Win10 and Sketchup Make 2017
I have a display issue with Sketchucation Tools : some icons are missing.

sketchucation.com and fontawesome.com are in whitelist in internet options.
I've installed IE-11 and I still have that issue.

Can you help me to solved it ?
