Got it down to 8 lines of code excluding spaces

```let html = '';
let randomRGB;
let randomValue = () => Math.floor(Math.random() * 256);

for(i=0; i<=10; i++){
randomRGB = `rgb( \${randomValue()}, \${randomValue()}, \${randomValue()} )`;
html += `<div style="background-color: \${randomRGB}">\${i}</div>`;
}

document.querySelector('main').innerHTML = html;
``` Good job! And if you convert randomRGB into a function, you can initialize it when you declare it, and save another line:

```let html = '';
let randomRGB = () => `rgb(\${randomValue()}, \${randomValue()}, \${randomValue()})`;
let randomValue = () => Math.floor(Math.random() * 256);

for (i = 0; i <= 10; i++) {
html += `<div style="background-color: \${randomRGB()}">\${i}</div>`;
}

document.querySelector('main').innerHTML = html;
```
