Is there any simple way to include with Grav ??

thanks!

There's no need to use a plugin. Just paste that code in a page .md file. Markdown allows plain HTML, so you can type any HTML code in markdown pages.

Alternatively, you can add it to a twig file provided by your template, so it will be included in all pages, just some pages, or anything that suits your requirements.

Thanks ! :)) In fact, what I tried to do was completely stupid. Indeed, my grav-blog is in https and the ifram contents http (non secure) address. So it did'nt match at all :)))

Beyond this, yes, we just have to enter html code in grav-markdown pages, and it works :)
