Hello, good. I'm doing what exercise sends correctly. But appears error. I have increased and decrease the page zoom the error changed to color. I wanted to help you. Since obliged already.
You must have an issue with the size
look at the proportion in my Preview-screen
In your index.html
do you have
<link type="text/css" rel="stylesheet" href="stylesheet.css"/>
hello, already I tried everything that was discussed, but is still the same error.
