CSS Display and Positioning
Clear

The float property can also be used to float multiple elements at once. However, when multiple floated elements have different heights, it can affect their layout on the page. Specifically, elements can “bump” into each other and not allow other elements to properly move to the left or right.

The clear property specifies how elements should behave when they bump into each other on the page. It can take on one of the following values:

  1. left — the left side of the element will not touch any other element within the same containing element.
  2. right — the right side of the element will not touch any other element within the same containing element.
  3. both — neither side of the element will touch any other element within the same containing element.
  4. none — the element can touch either side.
div { width: 200px; float: left; } div.special { clear: left; }

In the example above, all <div>s on the page are floated to the left side. The element with class special did not move all the way to the left because a taller <div> blocked its positioning. By setting its clear property to left, the special <div> will be moved all the way to the left side of the page.

Instructions

1.

Take a look at the .answer divs on the web page. They have been floated to the left, but the .question divs are touching the .answer divs on the right, let’s fix this.

In the .question selector, set the clear property to left. Notice how the questions moved.

2.

On second thought, this layout is not looking so good. Remove the float property from .answer and the clear property from .question.
