Adding search box to HTML document
Can any coding experts shed light on how to add a search box at the top when compiling an HTML document? There are plenty of suggested code sequences on the internet but with my very limited knowledge of coding I don't know which to use and I can't make any of them actually work. Viewing page source on other web pages for clues is too confusing and so doesn't help. If there is a simple solution I just need the HTML code and guidance as to where it should be inserted. Would it be between </head> and <body> ?
Thanks for info.
