Insert content right after the opening BODY tag

[kmarcink]

Hi there,

Could there be an action or a filter to enter code just after the opening BODY tag?

Google Tag Manager requires entering its tracking code there. I need to do it on each new website. Entering it into a theme file will make it disappear from the site when a client will want to change the theme.

Thanks,
Marcin

I believe this should be done in theme. It has nothing to do with core.

Hi @kmarcink. There was a push to implement a standard set of theme hooks a couple of years ago, but it never went very far.

Thanks guys for quick reply.

Maybe in the future, this standard will be used by theme developers.
