Article Introduction：C STL is a set of general template classes and functions, including core components such as containers, algorithms, and iterators. Containers such as vector, list, map, and set are used to store data. Vector supports random access, which is suitable for frequent reading; list insertion and deletion are efficient but accessed slowly; map and set are based on red and black trees, and automatic sorting is suitable for fast searches. Algorithms such as sort, find, copy, transform, and accumulate are commonly used to encapsulate them, and they act on the iterator range of the container. The iterator acts as a bridge connecting containers to algorithms, supporting traversal and accessing elements. Other components include function objects, adapters, allocators, which are used to customize logic, change behavior, and memory management. STL simplifies C

Article Introduction：The future development direction of CSS is exciting, and its core lies in the fact that language is gradually meeting the needs of modern web development. 1. The native cascade layer provides better style priority control to reduce specific conflicts; 2. The sub-grid supports the alignment of nested elements with the parent container to avoid redundant code; 3. Container query allows components to adapt based on container size to promote true component design; 4.:has() selector can set the conditional style according to the state of the internal element to reduce JavaScript dependencies. These features mark the positive evolution of CSS in a more expressive and logical direction. Some functions have been available in modern browsers.
