The float attribute is used to float elements in CSS.

css float attribute

float, as the name suggests, is floating. Elements with the float attribute set will float to the left or right according to the attribute value. We call it setting Elements with the float attribute are floating elements.

After an element uses the float attribute, the element can be separated from the standard flow itself and float on top of other elements, so that it no longer occupies the space originally belonging to the element. This will cause the subsequent elements to move up and merge. Takes up space that originally belonged to the element.

Attribute value

#left The element floats to the left.
right The element floats to the right.
none Default value. The element is not floated and appears where it appears in the text.

Understanding of float attribute

1. The float attribute only affects the element itself that uses this attribute and subsequent elements (the subsequent elements will move up--> Footer block moved up).

2. After the inline element uses the float attribute, it will become a block-level element, and the height and width of the element can be set (refer to the A tag).

3. The float attribute is generally used together with the clear attribute of the following tags to clear the impact of the float attribute on the following elements.

4. For elements using the float attribute, if the element width is not set, the element width is automatically adjusted to fit the width of the content (refer to content DIV--the size of the content block is not defined, so it is automatically adjusted).
