How does the `float` property work and how do you clear floats?
Article Introduction：The float attribute of CSS was originally designed to achieve the layout effect of text surrounding images, but was later widely used in page layout. float will cause elements to be separated from the document stream and arranged to the left or right, while other content surrounds it; multiple floating elements will be arranged horizontally as space allows, otherwise they will "drop" below. However, floating causes the parent container to collapse highly, which in turn causes release issues, so floating needs to be cleared. Common ways to clear floats include: 1. Add empty elements with clear:both after the floating element; 2. Use clearfix pseudo-element techniques; 3. Use modern layout methods such as Flexbox or Grid to replace float.

Describe the `opacity` property
Article Introduction：opacity is an attribute in CSS that controls the overall transparency of an element, with values ranging from 0 (fully transparent) to 1 (fully opaque). 1. It is often used for the image hover fade effect, and enhances the interactive experience by setting the opacity transition; 2. Making a background mask layer to improve text readability; 3. Visual feedback of control buttons or icons in the disabled state. Note that it affects all child elements, unlike rgba, which only affects the specified color part.

Rational application of opacity can enhance page hierarchy and interactivity, but it should avoid interfering with users.
