When copying some plug-ins, pay attention to some problems. For example, when copying the fancybox plug-in, you cannot just copy the css file alone.
Because some images will be used in the css file, there is a problem with the path. So make a copy of the entire content.
When setting the height of a div, if it is a percentage, then you need to set the height of its parent container, that is, set the height attribute, otherwise it will not take effect
| Inline object setting width, height is invalid. When set to inline-block, the object is still an inline object, but the content in it will become block-level, so the height and width settings will be effective. |
