CSS tag rendring

Question

Hi,

For navigation menu am using ul li. If there will be any change in performance if i use ol li. I appreciate your feedback.

Answer 1

Nope, there shouldn't be any. At least nothing a user or developer would ever notice.

Usually navigation menu consists of links in no particular order (other then the one in which you put em), that's why people use unordered list (ul). It's just a logical decision, you could easily simulate ul while using ol and vice versa using css and maybe a little bit more text.

Answer 2

I think the only difference is that ul is unordered list and ol is ordered list. I don't think there will be any performance concern in this. Even if there is any it won't be noticeable.

ol is used wherever there is a defined order of things that are displayed.

ul is used when the order of things doesn't matter.

See this SO post also for more details

when to use UL or OL in html?

Answer 3

Agree with the other guys. You will not get lower (or higher) performance if you use ol instead of ul.

Answer 4

The only difference is that <ol> has numbered points instead of bullets, but performance wise there is no difference.

Adding some CSS can make both look the same:

ol {
list-style:none;
}

or

ul {
list-style:none;
}
