vertical-align各属性对比_html/css_WEB-ITnose
测试用代码
<!DOCTYPE html><html><head> <style> #dd { //line-height: 300px; background-color: gray; position: relative; font-size: 60px; //height: 300px; } #dd > .middle { position: absolute; top: 50%; height: 1px; background-color: black; left: 0; right: 0px; } #dd span { background-color: green; } </style> </head><body> <div id="dd"> <img style="max-width:90%" alt="vertical-align各属性对比_html/css_WEB-ITnose" ><span>xg</span> <div class="middle"></div> </div></body></html>
默认的是按baseline对齐
去掉图片试试：
这里xg span的高度是60,68的高度是line-height,上图高72是图片把div撑开了，可以看出span的底部到baseline的距离是8
给img添加 vertical-align:bottom; 后：
图片和div的底边对齐
vertical-align:text-bottom
和对齐
vertical-align:sub;
和vertical-align:bottom;类似，但是更低一些
vertical-align:middle;
图片偏下了
将img的height改成1试一试
原来是跟x居中对齐了
