關於文字垂直置中，文字垂直置中
很多時候布局中需要文字垂直置中，有個CSS屬性：vertical-align: middle;該屬性在table裡用是有效果的，很多區塊層級元素沒反應。
這裡有2個屬性可以類比table，來讓vertical-align: middle屬性生效。
display: table和display: table-cell;
很簡單父級元素給固定寬高加上屬性display: table，子級元素給屬性display: table-cell和vertical-align: middle此時子集元素的文字自然垂直置中。
<!doctype html><html lang="en"><head> <meta charset="UTF-8"> <title>display:table</title> <style> *{ margin: 0; padding: 0; } .main{ display: table; width: 100px; height: 100px; border: 1px solid red; } .d1{ display: table-cell; vertical-align: middle; } .d1 h3{ text-align: center; } </style></head><body> <div class="main"> <div class="d1"> <h3>垂直置中</h3> </div> </div></body></html>
