display=none means that the tag in question will not appear on the page at all (although you can still interact with it through the DOM). There will be no space allocated for it between the other tags.

visibility=hidden means that unlike display:none, the tag is not visible, but space is allocated for it on the page. The tag is rendered, it just isn’t seen on the page.

The CSS box model is a container that contains multiple properties including borders, margin, padding, and the content itself. It is used to create the design and layout of web pages. It can be used as a toolkit for customizing the layout of different elements. The web browser renders every element as a rectangular box according to the CSS box model.

Box-Model has multiple properties in CSS. Some of them are given below:

```
borders
margins
padding
content
```

**Border Area:** It is the area between the box’s padding and margin. Its dimensions are given by the width and height of the border.

**Margin Area:** This area consists of space between border and margin. The dimensions of the Margin area are the margin-box width and the margin-box height. It is useful to separate the element from its neighbors.

**Padding Area:** It includes the element’s padding. This area is actually the space around the content area and within the border box. Its dimensions are given by the width of the padding-box and the height of the padding-box.

**Content Area:** This area consists of content like text, images, or other media content. It is bounded by the content edge and its dimensions are given by content box width and height.
