水平居中:
内联元素:text-align:center;相对于父级居中显示
块级元素:margin:0 auto;但是需要同时width,否则无法看到效果
多个块级元素居中:在此想要探讨一下display:inline-block;和display:flex;
方法1:在父级上设置text-align:center;在元素上设置:display:inline-block;同时为了使文字向左显示,设置了text-align:left;在浏览器中的显示为,子元素高度自适应,底部对齐。
方法2:在子元素上设置display:center;justify-content:center;子元素的高度一致,与元素中内容最多的高度相同。
二种方法在谷歌,火狐,360均兼容,但是第2种方法在IE10中不兼容,之前的IE版本可想也是不兼容的。当然在此也要处理由于浮动导致离层,父级背景颜色加不上去的问题。
1 <main class="inline-block-center"> 2 <div> 3 I‘m an element that is block-like with my siblings and we‘re centered in a row. 4 </div> 5 <div> 6 I‘m an element that is block-like with my siblings and we‘re centered in a row. I have more content in me than my siblings do. 7 </div> 8 <div> 9 I‘m an element that is block-like with my siblings and we‘re centered in a row. 10 </div> 11 </main>
1 <main class="flex-center"> 2 <div> 3 I‘m an element that is block-like with my siblings and we‘re centered in a row. 4 </div> 5 <div> 6 I‘m an element that is block-like with my siblings and we‘re centered in a row. I have more content in me than my siblings do. 7 </div> 8 <div> 9 I‘m an element that is block-like with my siblings and we‘re centered in a row. 10 </div> 11 </main>
1 body { 2 background: #f06d06; 3 font-size: 80%; 4 } 5 main { 6 background: white; 7 margin: 20px 0; 8 padding: 10px; 9 } 10 main div { 11 background: black; 12 color: white; 13 padding: 15px; 14 max-width: 125px; 15 margin: 5px; 16 } 17 .inline-block-center { 18 text-align: center; 19 } 20 .inline-block-center div { 21 display: inline-block; 22 text-align: left; 23 } 24 .flex-center { 25 display: flex; 26 justify-content: center; 27 }
垂直居中:
方法1:设置padding-top和padding-bottom的值相等
方法2:设置height和line-height的值相等
方法3:固定高度可以有一种处理方式position:absolute;top:50%;height:100px;margin-top:-50px;如果高度不固定,也可以使用js动态获取高度来。
还有css3的一些属性,考虑到兼容性问题不在叙述。
