Legacy Claris Home Page website uses X-SAS-WINDOW, can it be removed?

Question

I’ve been given a legacy website created in Claris Home Page. I did a wget on it, and have all the HTML and images from it working. However, it has stuff in the header such as:

<X-SAS-WINDOW TOP=66 BOTTOM=480 LEFT=8 RIGHT=538>

I’ve not been able to find any references to X-SAS-WINDOW. I’m going to guess that TOP, BOTTOM, LEFT and RIGHT has something to do with defining formatting. What made use of that X-SAS-WINDOW data?

Can I delete those from the header? If I left it there, will it cause any problems? Perhaps when it is indexed by search engines?

Answer 1

Well, I don’t know much about how Claris Home Page rendered pages, but <X-SAS-WINDOW> is definitely not a valid HTML tag since any tag that is prefixed by X- is an “unstandardized” element and the use of X- prefix on custom tags such as those has been depreciated since at least 2012.

It might just be a tag used internally by Claris Home Page—for things like window positioning on the desktop—but that’s it. I was able to find this Japanese page that clearly states when translated:

非標準 (Non-standard)

And shows that <X-SAS-WINDOW> tag paired with <!--This file created 02.5.11 10:31 AM by Claris Home Page version 2.0J--> so I am fairly confident that is a useless tag as far as standard HTML pages go and can be removed.

That said, since HTML pages are just text pages, I would encourage you to just make an archive of the site as it currently is before you make adjustments and then just remove the X-SAS-WINDOW stuff stuff for now when updating the site.

And if you are still unsure, just take the page and run it through an HTML validator such as this one.
