The new website is ready. The team is excited. Then someone says, "The big button does not work."

Leo is the web developer. He tries the button on his computer. It works. On another computer, it does not.

Leo is patient. He tests the button on three browsers. It fails on only one.

He is diligent and reads the code. He finds a tiny mistake: one line that only the old browser cannot read.

He changes the line and tests again. The button works everywhere.

The team cheers. Leo is good at his work, but he knows it was a small thing. Small things matter on a website.

A thought to keep

The smallest part can stop the whole page.
