This particular code is causing errors when validated by the W3 Validator, despite functioning correctly upon clicking.
<span href="#" class="click">+</span>
However, if I modify it to the code below, it passes the W3 validation test. But now, upon click, the pointer moves upwards on the screen instead of staying on the "+" symbol.
<a href="#" class="click">+</a>
Can you identify what might be the issue with this code?
