Course Introduction：The parallax scrolling effect can be implemented using CSS. There are three specific methods: First, use the background-attachment attribute, set the background-attachment:fixed; make the background image fixed, forming visual misalignment; second, use transform:translateZ() and perspective to set multiple levels in HTML and give different depths to simulate the 3D scrolling effect; third, combine HTML, CSS and JavaScript, dynamically adjust the style by listening to scroll events to achieve more complex animation effects. These three methods are applicable to basic parallax, full-screen display websites and high-definition

Course Introduction：The key to making parallax scrolling effect is to allow elements of different layers to scroll at different speeds. 1. First, build a multi-layer HTML structure, including background, medium scene and foreground, and use CSS to set the container overflow:hidden and absolute positioning; 2. Then listen to scroll events through JavaScript, use transform:translateY() to dynamically adjust the positions of each layer. The background layer scrolls slowly and the medium scene is slightly faster; 3. Finally, optimize performance, use throttling functions to control the scrolling frequency, compress image resources and adapt to the mobile terminal, and consider pure CSS solutions to improve compatibility.

Course Introduction：To create a pure CSS image light box, you need to use the:target pseudo-class to control the display; 1. Each thumbnail link points to the light box element with a unique ID; 2. The light box is hidden by default, and the flex is displayed in flex when the target matches and centers the large image; 3. Click the close link (href="#") to return to the top of the page and hide the light box; 4. You can add fade effect and visual closing buttons through CSS; this solution does not require JavaScript, but lacks keyboard support and scroll locking functions, which are suitable for lightweight static websites.

Course Introduction：CSS transitions enable switching between CSS attribute values ??through smooth animations, which are suitable for user interaction scenarios such as button hovering effects, menu expansion and collapse. Common usages include button closure effect, drop-down menu gradient, background color gradient, image transparency or zoom changes. The basic syntax is a transition: attribute duration time sequence function, which can specify a single or multiple attributes, or all can be used to represent all attributes, but it should be used with caution. Timing functions such as ease, linear, and ease-in-out control the animation speed curve, and can also be customized by cubic-bezier. It is recommended to prioritize opacity and transform for better performance, combined with @media(prefers-

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
