Is in with attendant creating introductory section of web site (4,4)
I believe the answer is:
home page
'introductory section of web site' is the definition.
I can't tell whether this defines the answer.
'is in with attendant' is the wordplay.
'is in' becomes 'home' ('he's in' can mean 'he's home').
'with' says to put letters next to each other.
'attendant' becomes 'page' (page is a kind of attendant).
'home'+'page'='HOME PAGE'
'creating' acts as a link.
Can you help me to learn more?
(Other definitions for home page that I've seen before include "Internet site intro" , "First point of call on website" , "introduction to site" , "Website domain?" , "website feature" .)
