Description

An element's margin controls the amount of space between an element's border and surrounding elements. If you set an element's margin to a negative value, the element will grow larger.

Instructions

Try to set the margin to a negative value like the one for the red box. Change the margin of the blue box to -15px, so it fills the entire horizontal width of the yellow box around it.

Tests

tests:
  - text: Your <code>blue-box</code> class should give elements <code>-15px</code> of <code>margin</code>.
    testString: assert($(".blue-box").css("margin-top") === "-15px", 'Your <code>blue-box</code> class should give elements <code>-15px</code> of <code>margin</code>.');
