Please answer a question before I suggest you the best thing.
Do you want this codes to be reflected in all pages or any single page?
Hi Ankushr, I would like the codes on all pages. Thanks
In this case, I suggest you placing the code in metadata section if your master page.
the codes will effect on all the pages on which the respective master has been applied.
And yes you can anytime place more than once codes in the metadata.
That's great Ankush, thank you!
