That moment when you have hundreds of lines of code for your website, then you wanted to add a simple modal which looks great on w3school.

Then you recreate the modal on your site, click the button and nothing happens....

So now, you are spending hours trying to figure out why it's not working, new file to test, tried another modal concept, change the CSS, refresh the page until the F5 button doesn't even work anymore!!!

To find out, there is a extra "." in the href file tag plus the tag is in a id not a class
