需求:一个div设置了background: url,如今须要使图片背景模糊,div内的文字清晰显示。html
原始代码:web
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <style type="text/css"> .content { color: #ffffff; font-size: 40px; } .bg { background: url('1.jpg'); background-repeat: no-repeat; background-position: center; background-size: cover; height:600px; text-align: center; line-height: 600px; } </style> </head> <body> <div class="bg"> <div class="content">我是内容</div> </div> </body> </html>
原始效果: markdown
解决方法:内容和图片分别置于一个div,经过css设置背景div模糊度,设置内容div绝对位置。url
html代码:spa
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <style type="text/css"> .content { color: #ffffff; font-size: 40px; } .bg { background: url('1.jpg'); height:600px; text-align: center; line-height: 600px; } .bg-blur { float: left; width: 100%; background-repeat: no-repeat; background-position: center; background-size: cover; -webkit-filter: blur(15px); -moz-filter: blur(15px); -o-filter: blur(15px); -ms-filter: blur(15px); filter: blur(15px); } .content-front { position:absolute; left: 10px; right: 10px; height:600px; line-height: 600px; text-align: center; } </style> </head> <body> <div> <div class="bg bg-blur"></div> <div class="content content-front">我是内容</div> </div> </div> </body> </html>
效果: .net
