When we usually lay out the website, we want to hide the p, but many people don’t know how to control the display and hiding of p using css? Let's explain how to hide p with css.
1. Use display:none to hide div
We can use the display:none attribute to hide all information, including text and pictures, the syntax is:

When we use the css style in p, we can use the display:none attribute to hide the content, and it is not visible through the browser. At the same time, the hidden content does not occupy space and is hidden. The subsequent content will not be read by search engines. Generally, we use js statistics code to hide the displayed icons.
2. Use visibility: hidden; to hide the div
The visibility attribute specifies whether the element is visible.
This attribute specifies whether to display the element box generated by an element. This means that the element still occupies its original space, but can be completely invisible. The value collapse is used in tables to remove columns or rows from the table layout.
Attribute value:
visible default value. The element is visible.
hidden elements are invisible.
collapse When used within a table element, this value deletes a row or column, but it does not affect the layout of the table. The space occupied by a row or column is freed for other content. If this value is used on another element, it will be rendered as "hidden".
3. Use opacity: 0 to hide the div
The opacity attribute means to set the transparency of an element. It is not designed to change the bounding box of an element.
This means that setting opacity to 0 only visually hides the element. The element itself still occupies its own position and contributes to the layout of the web page. This is similar to visibility: hidden above.
