1 <template> 2 <div> 3 <div class="top">上列</div> 4 <div class="bottom">下列</div>
5 </div> 6 </template> 7 8 <script> 9 export default { 10 name: ‘Home‘ 11 } 12 </script> 13 14 <style scoped> 15 .top{ 16 background: blue; 17 width: 300px; 18 height: 300px; 19 } 20 .bottom{ 21 background: red; 22 height: 300px; 23 width: 300px; 24 } 25 </style>
1 <template> 2 <div> 3 <div class="top">上列</div> 4 <div class="bottom">下列</div>
5 </div> 6 </template> 7 8 <script> 9 export default { 10 name: ‘Home‘ 11 } 12 </script> 13 14 <style scoped> 15 .top{ 16 background: blue; 17 width: 300px; 18 height: 300px; 19 border: 55px solid #111; 20 } 21 .bottom{ 22 background: red; 23 height: 300px; 24 width: 300px; 25 } 26 </style>
可见,并没有使整体变大,而是让里面的内容变小了;
1 <template> 2 <div> 3 <div class="top">上列</div> 4 <div class="bottom">下列</div>
5 </div> 6 </template> 7 8 <script> 9 export default { 10 name: ‘Home‘ 11 } 12 </script> 13 14 <style scoped> 15 .top{ 16 background: blue; 17 width: 300px; 18 height: 300px; 19 border: 55px solid #111; 20 margin: 10px; 21 } 22 .bottom{ 23 background: red; 24 height: 300px; 25 width: 300px; 26 } 27 </style>
可以看出,上列的大小不变,但位置进行了移动,且保持与其它元素一定的距离;
1 <template> 2 <div> 3 <div class="top">上列</div> 4 <div class="bottom">下列</div>
5 </div> 6 </template> 7 8 <script> 9 export default { 10 name: ‘Home‘ 11 } 12 </script> 13 14 <style scoped> 15 .top{ 16 background: blue; 17 width: 300px; 18 height: 300px; 19 border: 55px solid #111; 20 margin: 10px; 21 padding: 20px; 22 color: aliceblue; 23 } 24 .bottom{ 25 background: red; 26 height: 300px; 27 width: 300px; 28 } 29 </style>
可以看出,上列两个字往内进行了收缩。
1 <template> 2 <div> 3 <div class="top">上列</div> 4 <div class="bottom">下列</div> 5 </div> 6 </template> 7 8 <script> 9 export default { 10 name: ‘Home‘ 11 } 12 </script> 13 14 <style scoped> 15 .top{ 16 background: blue; 17 width: 300px; 18 height: 300px; 19 border: 55px solid #111; 20 margin: 10px; 21 color: aliceblue; 22 } 23 .bottom{ 24 background: red; 25 height: 300px; 26 width: 300px; 27 border: 55px solid #111; 28 margin: 10px; //这里margin作为对比,前者不加,后者加 29 } 30 </style>
从对比效果图可以看出,上下列的margin被抵消了1个10px;同时,若二者大小不同,以较大的margin值为准。
1 <template> 2 <div> 3 <div class="top">上列</div> 4 <div class="bottom">下列</div>
5 </div> 6 </template> 7 8 <script> 9 export default { 10 name: ‘Home‘ 11 } 12 </script> 13 14 <style scoped> 15 .top{ 16 background: blue; 17 width: 300px; 18 height: 300px; 19 border: 55px solid #111; 20 margin: 10px; 21 color: aliceblue; 22 float: left; 23 } 24 .bottom{ 25 background: red; 26 height: 300px; 27 width: 300px; 28 border: 55px solid #111; 29 margin: 10px; 30 float: left; 31 clear: left; 32 } 33 </style>
可以看出,这时二者中间的宽度为20px;
按照书上的写法会报错,以后再来验证吧!
