div周围的CSS3渐变边框

Question

Is it possible to create such border around div using pure CSS, or do I have to use image for this?

Answer 1

I recommend using border-image property

 .top-to-bottom { border-bottom: 10px solid trasparent; border-width: 10px; border-style: solid; -webkit-border-image: -webkit-gradient(linear, 0 0, 0 100%, from(black), to(rgba(0, 0, 0, 0))) 1 100%; -webkit-border-image: -webkit-linear-gradient(#FBCDEA, rgba(0, 0, 0, 0)) 1 1; -moz-border-image: -moz-linear-gradient(#FBCDEA, rgba(0, 0, 0, 0)) 1 1; -o-border-image: -o-linear-gradient(#FBCDEA, rgba(0, 0, 0, 0)) 1 1; border-image: linear-gradient(to bottom, #FBCDEA, rgba(0, 0, 0, 0)) 1 1; height: 100px; width: 97%; border-top: 10px solid #FBCDEA; } .bottom-to-top { border-top: 10px solid trasparent; border-width: 10px; border-style: solid; -webkit-border-image: -webkit-gradient(linear, 0 100%, 0 0, from(#FBCDEA), to(rgba(0, 0, 0, 0))) 1 1; -webkit-border-image: -webkit-linear-gradient(bottom, black, rgba(0, 0, 0, 0)) 1 1; -moz-border-image: -moz-linear-gradient(bottom, #FBCDEA, rgba(0, 0, 0, 0)) 1 1; -o-border-image: -o-linear-gradient(bottom, #FBCDEA, rgba(0, 0, 0, 0)) 1 1; border-image: linear-gradient(to top, #FBCDEA, rgba(0, 0, 0, 0)) 1 1; border-bottom: 10px solid #FBCDEA; height: 100%; width: 98% } 

  <div class="bottom-to-top"> <div class="top-to-bottom"> </div> </div> 

Answer 2

Since you want to do pure css , here's one way:

 .dblgradbox { margin: auto; padding: 15px; width: 275px; height: 200px; border: 15px solid transparent; border-top: 10px solid transparent; border-image: linear-gradient(to bottom, transparent, #FBCDEA) 3 100%; box-shadow: 0 15px 0 0 #FBCDEA, 0 -5px 0 0 #F7FCFF, inset 0px 15px 0 0 #FBCDEA; background-image: linear-gradient(#FBCDEA, transparent), linear-gradient(#FBCDEA, transparent); background-size: 15px 100%; background-position: 0 0, 100% 0; background-repeat: no-repeat; border-radius: 7px; } 

 <div class="dblgradbox"> x3ns </div> 

See if "Full Page" after running snippet. I didn't include any cross-browser properties as this is an example.

This method works by normally applying a gradient border, and the using a box-shadow inset technique to aid in completing the effect within the element - thus also a padding is required to fit content within. The background-image only display two gradient bars on both sides of inset.

maybe so?

 *{ box-sizing: border-box; } .wrap{ width: 300px; height: 300px; padding: 20px; margin: 25px auto; border-radius: 10px; background: rgb(254,249,253); /* Old browsers */ background: -moz-linear-gradient(top, rgb(254,249,253) 0%, rgb(253,230,246) 50%, rgb(253,204,234) 100%); /* FF3.6+ */ background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgb(254,249,253)), color-stop(50%,rgb(253,230,246)), color-stop(100%,rgb(253,204,234))); /* Chrome,Safari4+ */ background: -webkit-linear-gradient(top, rgb(254,249,253) 0%,rgb(253,230,246) 50%,rgb(253,204,234) 100%); /* Chrome10+,Safari5.1+ */ background: -o-linear-gradient(top, rgb(254,249,253) 0%,rgb(253,230,246) 50%,rgb(253,204,234) 100%); /* Opera 11.10+ */ background: -ms-linear-gradient(top, rgb(254,249,253) 0%,rgb(253,230,246) 50%,rgb(253,204,234) 100%); /* IE10+ */ background: linear-gradient(to bottom, rgb(254,249,253) 0%,rgb(253,230,246) 50%,rgb(253,204,234) 100%); /* W3C */ filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#fef9fd', endColorstr='#fdccea',GradientType=0 ); /* IE6-9 */ } .wrap div{ width: 100%; height: 100%; padding: 20px; } .wrap .inner{ background: rgb(253,204,234); /* Old browsers */ background: -moz-linear-gradient(top, rgb(253,204,234) 0%, rgb(253,230,246) 50%, rgb(254,249,253) 100%); /* FF3.6+ */ background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgb(253,204,234)), color-stop(50%,rgb(253,230,246)), color-stop(100%,rgb(254,249,253))); /* Chrome,Safari4+ */ background: -webkit-linear-gradient(top, rgb(253,204,234) 0%,rgb(253,230,246) 50%,rgb(254,249,253) 100%); /* Chrome10+,Safari5.1+ */ background: -o-linear-gradient(top, rgb(253,204,234) 0%,rgb(253,230,246) 50%,rgb(254,249,253) 100%); /* Opera 11.10+ */ background: -ms-linear-gradient(top, rgb(253,204,234) 0%,rgb(253,230,246) 50%,rgb(254,249,253) 100%); /* IE10+ */ background: linear-gradient(to bottom, rgb(253,204,234) 0%,rgb(253,230,246) 50%,rgb(254,249,253) 100%); /* W3C */ filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#fdccea', endColorstr='#fef9fd',GradientType=0 ); /* IE6-9 */ } .wrap .item{ background: #fff; } 

 <div class="wrap"> <div class="inner"> <div class="item"></div> </div> </div>
