I'm wondering how I could expand a 'div' without affecting the layout of the other elements in the page. Specifically, I'd like to achieve an effect similar to this - http://www.ikea.com/us/en/catalog/categories/departments/kitchen/kitchen_int_lighting/. If you hover your mouse over any product, you'll see that the box expands showing more information; however, other elements such as the product image below is not affected by the expansion.
我想知道如何在不影响页面中其他元素布局的情况下扩展“div”。具体来说，我想达到类似的效果 - http://www.ikea.com/us/en/catalog/categories/departments/kitchen/kitchen_int_lighting/。如果您将鼠标悬停在任何产品上，您会看到该框展开显示更多信息;但是，其他元素（如下面的产品图片）不受扩展影响。

use absolute position.
rather you can also achive the same effect by writing onhover event on the div with adding an additional div at that position with higher z-index.

Add position:absolute; to style of your div. This way it won't interfere with other elements but still overlap them, and you can specify any width and height to them.

Absolutely position your div and make sure the z-index is at the top level. It CAN be done using just CSS, but it'll probably be easier with js as well.
绝对定位你的div并确保z-index处于顶层。它可以使用CSS完成，但是js也可能更容易。
