--description--

We can clean up our code and make our Cat Photo App look more conventional by using Bootstrap's built-in styles instead of the custom styles we created earlier.

Don't worry - there will be plenty of time to customize our CSS later.

Delete the .red-text, p, and .smaller-image CSS declarations from your style element so that the only declarations left in your style element are h2 and thick-green-border.

Then delete the p element that contains a dead link. Then remove the red-text class from your h2 element and replace it with the text-primary Bootstrap class.

Finally, remove the smaller-image class from your first img element and replace it with the img-responsive class.

--hints--

Your h2 element should no longer have the class red-text.

assert.isFalse(document.querySelector('h2')?.classList?.contains('red-text'));

Your h2 element should now have the class text-primary.

assert.isTrue(document.querySelector('h2')?.classList?.contains('text-primary'));

Your paragraph elements should no longer use the font Monospace.

const paragraphElement = document.querySelector('p');
const paragraphFontFamily = window.getComputedStyle(paragraphElement)["font-family"]; 
assert.notMatch(paragraphFontFamily,/monospace/i);

The smaller-image class should be removed from your top image.

assert.isFalse(document.querySelector('img')?.classList?.contains('smaller-image'));

You should add the img-responsive class to your top image.

assert.lengthOf(document.querySelectorAll('.img-responsive'),2);
