The curious case of banner468

On one of my websites, I used a CSS class called "banner468". As the name suggests the original purpose of the class was to hold some ads. I used it for a different purpose. From one day to the next, the functionality contained within the banner468, disappeared. It got hidden. Originally, I thought, this had something to do with my ability to write JS, but no. After some digging and thinking it hit me! The AdBlocker was blocking the content of the banner. I renamed it and it works! 😀
