Course Introduction：You can use CSS3 and SVG to create a circular progress bar animation effect. The steps are as follows: Create an SVG element and define a circular path; set a dotted line style for the circular path; use CSS3 animation to control the offset of the dashed line; set a progress percentage by adjusting the initial offset of the dashed line.

Course Introduction：To create a CSS flip effect, the key is to use transform-style:preserve-3d and rotateY() or rotateX() functions in combination. 1. Build an HTML structure and simulate a card with a container containing the front and back sides; 2. Use CSS to locate the front and back sides and set backface-visibility:hidden to hide the content on the back; 3. Trigger the flip animation through:hover pseudo-class or JavaScript to achieve an interactive flip effect.

Course Introduction：To achieve the rotation effect of an element, use JavaScript combined with CSS3's transform attribute. 1. Use transform's rotate() function to set the rotation angle. 2. Realize dynamic rotation through requestAnimationFrame. 3. Consider reducing DOM operations or using CSS animations when optimizing performance. 4. Ensure browser compatibility and add prefixes. 5. User interactive control rotation is achieved through mouse or touch events.

Course Introduction：WebGL is a JavaScript API that allows hardware-accelerated 2D and 3D graphics rendering in the browser. It is based on OpenGLES2.0 and can use the GPU to achieve high-performance graphics processing without plug-ins. It is suitable for applications such as gaming, data visualization and interactive animation. The reasons why the front-end uses it include: 1. Support cross-platform operation; 2. No additional plug-ins are required; 3. It can be combined with HTML/CSS/JS to build a complete interactive experience; 4. There are rich libraries to support such as Three.js, Babylon.js, etc. To start creating a 3D scene with WebGL, the basic steps are: get canvas and initialize the context; write and compile the shader; link the program; set the number of incoming vertices in the buffer

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.
