HTML page title rules?

No space in HTML page titles?

[Rose_1171]

Also is there any rule that HTML page Titles should not have any space in them. for example "my_company Rose" is right to give as a heading to a page? or that it should have "no space" in between them which means it would be sth. like "my_company_rose".
appreciate help!
Regards,

If you are talking about the page title as given withing the title tag, then you can include spaces as normal:

<title>My company name</title>

If you are talking about the file name or the address for the page, it is best practice not to use spaces, capitals or punctuation. For readability, I find using a hyphen to be best, as the underscore can disappear within a link:

http://www.example.com/the-name-of-my-page.html
