What are the float methods?

Float modes include left floating, right floating, clear floating, and no floating. Detailed introduction: 1. Float left (float: left): The element floats to the left, freeing up space on the right for other elements. The left-floated element will stick to the floating element in front of it or the left boundary of the container; 2. Float right (float: right): The element floats to the right, freeing up the left space for other elements. The right-floated element will stick to the floating element in front of it or the right boundary of the container; 3. Clear the float (clear: both) and so on.

Float (float) is a commonly used layout method in CSS, which allows elements to float to a specified position on the page. Through floating, you can achieve multi-column layout, picture wrapping text and other effects. In CSS, there are the following floating methods:

1. Float left (float: left): The element floats to the left, freeing up space on the right for other elements to use. A left-floated element will stick to the floated element before it or the left edge of the container.

2. Float right (float: right): The element floats to the right, freeing up the left space for other elements. A right-floated element will stick to the floated element before it or the right edge of the container.

3. Clear float (clear: both): Used to clear the impact of floating elements on subsequent elements. When an element is set with the clear float attribute, it will automatically wrap and stick to the lower boundary of the previous floating element.

4. No float (float: none): Cancel the floating effect of the element and return the element to the normal document flow.

The characteristic of floating elements is that the floating elements will break away from the document flow, and the parent element of the floating element will collapse, resulting in the height of the parent element not being able to expand automatically. In order to solve this problem, you can add a clearfix class to the parent element of the floating element, and clear the impact of the floating element on the parent element by setting the style of the clearfix class.

Floating elements are widely used, especially in implementing multi-column layouts, pictures around text, etc. By setting different floating methods, different layout effects can be achieved. For example, left-floating elements can achieve multi-column layout, and right-floating elements can achieve the effect of pictures wrapping text.

It should be noted that the order of floating elements will affect their position on the page. The higher the order of floated elements, the higher they appear on the page. Therefore, when using floating layout, you need to pay attention to the order of elements to achieve the expected layout effect.

To sum up, floating is a commonly used layout method in CSS. By setting different floating methods, you can achieve multi-column layout, picture wrapping text and other effects. When using float layout, you need to pay attention to the order of floated elements and the impact of clearing floats on subsequent elements.
