--description--

Sometimes you will want to customize an element so that it has a different margin on each of its sides.

CSS allows you to control the margin of all four individual sides of an element with the margin-top, margin-right, margin-bottom, and margin-left properties.

--instructions--

Give the blue box a margin of 40px on its top and left side, but only 20px on its bottom and right side.

--hints--

Your blue-box class should give the top of elements 40px of margin.

const blueBox = document.querySelector('.blue-box');
const marginTop = window.getComputedStyle(blueBox)['margin-top'];
assert.strictEqual(marginTop, '40px');

Your blue-box class should give the right of elements 20px of margin.

const blueBox = document.querySelector('.blue-box');
const marginRight = window.getComputedStyle(blueBox)['margin-right'];
assert.strictEqual(marginRight, '20px');

Your blue-box class should give the bottom of elements 20px of margin.

const blueBox = document.querySelector('.blue-box');
const marginBottom = window.getComputedStyle(blueBox)['margin-bottom'];
assert.strictEqual(marginBottom, '20px');

Your blue-box class should give the left of elements 40px of margin.

const blueBox = document.querySelector('.blue-box');
const marginLeft = window.getComputedStyle(blueBox)['margin-left'];
assert.strictEqual(marginLeft,'40px');
