CSS visibility Tutorial
View more Tutorials:
CSS Visibility is used to hide or display an element without changing document Layout. It can also hide a row or a row group, or a column or a column group of a table.
/* Example: */ visibility: visible|hidden|collapse|initial|inherit;
The possible values of CSS Visibility:
| Value | Description |
| visible | (default), "Visible" elements are default. |
| hidden | Make an element invisible, but it still takes up space. |
| collapse | This value is used for only the elements <thead>, <tbody>, <tfoot>, <tr>, <col>, <colgroup> (of a table) to hide this element, and release space occupied by it. If you use this value for other elements, it will work as similarly as the "hidden" value does. |
| initial | Set this property to default value. |
| inherit | Its value will be inherited from the parent element. |
CSS {display:none} also hides an element, but it releases the space which it occupies, so it can change document layout.
CSS {visibility:hidden} makes an element invisible, but it doesn't release the space which the element occupies, so it doesn't change document layout.

<thead>, <tbody>, <tfoot>, <tr>

If you want to hide one or more columns of a table, it is best to hide all the cells of those columns, which is supported by all browsers.
