根据下列CSS设置,请计算盒子的总宽度和高度。#div1{width:200px;height:300px;border:1pxsolidred;padding:5px10px;margin:10px;}
举一反三
- 设置DIV宽为500像素和高为400像素的正确方法是？ A: height:500 px; width:400 px; B: margin:500px; padding:400 px; C: padding:500 px;margin:400 px; D: width:500 px;height:400 px;
- 第一个DIV的样式style为width:150px;height:50px;margin:5px 7px 2px 3px;padding:5px;border:1px solid #000;第二个DIV的样式style为width:150px;height:50px;margin:0;padding:0;border:1px solid #000;请问第一个DIV的实际宽度为________px，原点坐标为x=_____px，y=______px;第二个DIV的原点坐标为x=_____px，y=______px原点为盒子模型可见区域的左上角定点
- 有以下程序段:#include int main(){int x[ ] = {10, 20, 30}; int *px = x;printf("%d, ", ++*px); printf("%d, ", *px); px = x;printf("%d, ", (*px)++); printf("%d, ", *px); px = x;printf("%d, ", *px++); printf("%d, ", *px); px = x;printf("%d, ", *++px); printf("%d\n", *px);return 0;}程序运行后的输出结果是( ) A: 20, 10, 11, 10, 11, 10, 11, 10 B: 11, 11, 11, 12, 12, 20, 20, 20 C: 20, 10, 11, 20, 11, 12, 20, 20 D: 11, 11, 11, 12, 12, 13, 20, 20
- 有以下程序段：#include stdio.hint main(){int x[ ] = {10, 20, 30}; int *px = x;printf(%d, , ++*px); printf(%d, , *px); px = x;printf(%d, , (*px)++); printf(%d, , *px); px = x;printf(%d, , *px++); printf(%d, , *px); px = x;printf(%d, , *++px); printf(%d\n, *px);return 0;}程序运行后的输出结果是（ ）｡ A: 11, 11, 11, 12, 12, 20, 20, 20 B: 20, 10, 11, 10, 11, 10, 11, 10 C: 11, 11, 11, 12, 12, 13, 20, 20 D: 20, 10, 11, 20, 11, 12, 20, 20
- 程序：char xdata *pX; pX = 0xA0; *pX = 0x80,其中pX是
