Ampersand
Several blogs ago, I used AT&T as the title of a post. I learned later that the ampersand sign caused my pages to fail the W3C validation test. At first, I was a bit perplexed as to how my pages were broken since I haven’t made any code changes in a while.
Upon further review, I found out that the problem was the ampersand character I used in the word “AT&T.” To fix the problem, I had to use the HTML code & or ESC key character & to make my pages pass the validation test.
The ampersand characters inside a WordPress post doesn’t seem to break the validation test, but only the ones in the title field. Interesting, indeed.
