It sure is hot tonight in Tuggeranong.

Were you able to work out what were the HTML errors?

Here is my take on what actually caused the HTML errors to be
reported. Can anyone confirm my reasoning, and tell me where my
reasoning is incorrect, please?

Using Firefox to inspect the HTML of
There is a single "

tag. According to  https://www.w3schools.com/tags/tag_ul.asp the "

" should be directly followed by a "
	* ", which it is not, nor is the a "

" ending tag.

I do not know why "{Line 159, Column 31: document type does not allow
element "TABLE" here...", but I suspect that tables are not allowed
within "" tags. I assume the errors on lines 162, 162, and 163 are
also due to being within the "" tags?

Is anyone able confirm why this error message is given? I have not
tried to recreate the error, which is one way to check.

The Web page may look okay but so many developers don't validate and
so the Webb pages don't present properly on obscure web browsers and
applications that interpret the HTML for other output, such as,

see  when
the HTML is invalid.}

So I used that site to check CLUG's pages.

This was flawless.

But this gave two errors and 4 warnings!
