常规遮罩层
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no"> <title>Title</title> <style> .mask{ position: absolute; width: 100%; height: 100%; top: 0; left: 0; background: rgba(0,0,0,0.4); display: flex; justify-content: center; align-items: center; z-index: 3; } .mask{ position:fixed; top : 0; left : 0; bottom : 0; right : 0; background:rgba(0,0,0,.5); /*background:hsla(0,100%,80%,0.5)*/ /*background:#000; opacity:0.5; */ } //模糊效果 毛玻璃效果 .blur{ -webkit-filter: blur(5px); /* Chrome, Opera */ -moz-filter: blur(5px); -ms-filter: blur(5px); filter: blur(5px); } </style> </head> <style> </style> <body> <div class='mask'></div> </body> </html>
镂空遮罩层效果如图
使用box-shadow实现镂空遮罩引导层效果
优势：html
- 圆角轻松实现；
- box-shadow 不会影响元素位置，定位只须要根据 content 的位置写。
缺点：阴影可视区域没法触发click事件，所以，当点击蒙层任意区域，没法隐藏。web
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no"> <title>Title</title> <style> .guide{ position: absolute; z-index: 2; top: 0px; left: 50%; transform: translateX(-50%); width: 50px; height: 50px; border-radius: 50px; border: 3px solid #2353FA; box-shadow: 0px 0px 0px 1000px rgba(0,0,0,.75); box-sizing: border-box; } </style> </head> <style> </style> <body> <div class='guide'></div> </body> </html>
使用border实现镂空遮罩引导层效果
缺点：代码量大ide
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no"> <title>Title</title> <style> .guide{ position: absolute; z-index: 2; .opacityEle{ border: 700px solid rgba(0,0,0,0.75); width: 50px; height: 50px; position: relative; top: -700px; left: -538px; border-radius: 50%; .ele{ width: 50px; height: 50px; border: 3px solid #0B6EFF; border-radius: 25px; box-sizing: border-box; } } } </style> </head> <style> </style> <body> <div class='guide'> <div class='opacityEle'> <div class='ele'></div> </div> </div> </body> </html>
