JavaScript and HTML h1 { color:blue; background-color:lightGreen; border:12px solid green; padding: 5px; border-radius: 15px; text-align: center; }

Sol59:

It looks like you have started to write an HTML file with some CSS styling for a h1 element. However, there is no content inside the head or body tags, so the file is incomplete. To make it a valid HTML file, you can add some content inside the body tags, like this:

JavaScript and HTML

h1 {

color:blue;

background-color:lightGreen;

border:12px solid green;

padding: 5px;

border-radius: 15px;

text-align: center;

}

Welcome to my website!

This is a paragraph of text that you can replace with your own content.

In this example, we added a h1 element with some CSS styling, and a p element inside the body tags. You can replace the content inside the p element with your own text or other HTML elements as needed.
