What are the positioning of static web pages?

The positioning of static web pages includes static positioning, relative positioning, absolute positioning, fixed positioning, sticky positioning, etc. Detailed introduction: 1. Static positioning, which is the default positioning method of elements. In static positioning, elements are laid out in the order they appear in the HTML document. They will not be affected by other elements and cannot be adjusted through other attributes. Their positions; 2. Relative positioning, which is relative to the initial position of the element in the document. You can move the element relative to its initial position by setting attributes; 3. Absolute positioning, which is relative to the nearest one, etc.

Static web pages refer to web pages whose content will not change with user operations. When developing static web pages, we need to set positioning for elements (such as text, images, videos, etc.) to ensure that they are displayed and laid out correctly on the page. The following are several common static web page positioning methods:

1. Static positioning (static): This is the default positioning method of elements. In static positioning, elements are laid out in the order they appear in the HTML document. They are not affected by other elements, and their position cannot be adjusted through the top, right, bottom, and left properties.

2. Relative positioning (relative): Relative positioning is relative to the initial position of the element in the document. By setting the top, right, bottom, and left properties, you can move an element relative to its initial position. Relative positioning does not affect the layout of other elements, so other elements are still laid out in the order they appear in the document.

3. Absolute positioning (absolute): Absolute positioning is positioned relative to the nearest positioned ancestor element. If there is no positioned ancestor element, then it will be positioned relative to the initial position of the document. By setting the top, right, bottom, and left attributes, you can position the element where you want it. Absolute positioning removes an element from the normal document flow, so the layout of other elements is affected.

4. Fixed positioning (fixed): Fixed positioning is positioned relative to the browser window. No matter how the user scrolls the page, fixedly positioned elements will always remain in the same position in the window. By setting the top, right, bottom and left properties, you can fix the element at the desired position. Fixed positioning also removes elements from the normal document flow, so the layout of other elements is affected.

5. Sticky positioning (sticky): Sticky positioning is positioned relative to the element's position in the normal document flow and the nearest ancestor element with a scrolling mechanism. When the page scrolls to a specific location, sticky-positioned elements stay fixed at that location. By setting the top, right, bottom, and left properties, you can adjust the offset of an element at a specific position. Sticky positioning may not be supported in some browsers.

The above are commonly used positioning methods in static web pages. Based on actual needs and design requirements, we can choose appropriate positioning methods to layout and position elements on the page to achieve the desired effect.
