In-depth understanding of float, inline-block, and floatinline-block This article mainly introduces the introduction of float and inline-block, and analyzes the compatibility and influence on the parent element. It is recommended for reference by our partners. Recently, my work is relatively easy, so I have been writing my own canvas library .. I have no good kno

First of all, to popularize memory storage area knowledge: Memory is divided into five areas: heap, stack, global zone, literal constant area, code areaHeap Storage: A block of memory allocated by new, ALLOC, controlled by the programmer to release P1 = (char *) malloc;Stack storage: Store function parameters, local variables, variable stores that are automatically purged by the compiler when they are not needed. int b; Char s[] = "ABC"; CHAR*P2

(block formatting context) literal translation is "chunk-level formatting contexts". It is a separate rendering area that only block-level box participates in, which specifies how the internal block-level box is laid out and irrelevant to the outside of the area.
