CSS connection

Question

css

Condition:

There is ONLY one *.css stylesheet, several *.html pages.
For example, page #1 uses the <td> tag a lot of times. Page #2 also has these tags.

Task:

How, by connecting one style file, to make sure that the styles for the TD tag (in this case) are identified by only one page.

Comment:

Class identification in each TD tag is not very satisfying.

With me plus + karma.

Answer 1

in html do this:
in css:
#page1 td {
…
}
Similarly for another page
