--description--

Nest a div with a class of bb1 in the background buildings container. Open your styles.css file, and give .bb1 a width of 10% and height of 70%. "bb" stands for "background building", this will be your first building.

--hints--

You should create a new div element.

assert.equal(document.querySelectorAll('div').length, 2);

You should give the new div a class of bb1.

assert.exists(document.querySelector('div.bb1'));

You should use a .bb1 class selector to style the element.

assert.exists(new __helpers.CSSHelp(document).getStyle('.bb1'));

You should give the .bb1 element a width of 10%.

assert.equal(new __helpers.CSSHelp(document).getStyle('.bb1')?.width, '10%');

You should give the .bb1 element a height of 70%.

assert.equal(new __helpers.CSSHelp(document).getStyle('.bb1')?.height, '70%');
