Create Ribbon With Css

I have sidebar menu finally created. now I need create ribbon on selected item like show image (red) (I need really gray color ribbon). But I don't want use image background and us

Solution 1:

this will have to be adapted to your needs, but something using pseudo elements would make this possible:

.box{
  height:300px;
  width:300px;
  box-shadow:inset 0015px#222;
  position:relative;
  margin:0 auto;
  background:gray;
  }

.active{
  position:absolute;
  top:30px;
  left:-5%;
  height:30px;
  width:105%;
  background:tomato;
  border-radius: 5px000;
  }
.active:before{
  content:"";
  position:absolute;
  height:16px;
  top:5px;
  left:0;
  width:100%;
  border-top:2px dashed red;
  border-bottom:2px dashed red;
  }
.active:after{
  content:"";
  position:absolute;
  right:-10px;
  height:20px;
  width:20px;
  top:5px;
  background:tomato;
  border-radius: 05px00;
  transform:rotate(45deg);  
  }
.activea{
  position:absolute;
  top:0;
  left:0;
  height:100%;
  width:100%;
  text-align:center;
  display:inline-block;
  text-decoration:none;
  line-height:30px;
  }
.activea:after{
  content:"";
  position:absolute;
  bottom:-15px;
  left:6px;
  height:30px;
  width:30px;
  background:darkred;;
  transform:rotate(45deg);  
  z-index:-2;
  }

<divclass="box"><divclass="active"><ahref="#">some text</a></div></div>

note

the transform property will require prefixes as well.

Solution 2:

it's real with CSS3.

maybe like this:) but you need to customize.

html:

* {
  box-sizing: border-box;
}
.container {
  width: 80%;
  max-width: 1000px;
  height: 80px;
  margin: 40px auto;
  position: relative;
}
.one > div {
  height: 50px;
}
.main {
  background: #0fadc0;
  position: relative;
  display: block;
  width: 90%;
  left: 50%;
  top: 0;
  padding: 5px;
  margin-left: -45%;
  z-index: 10;
}
.main > div {
  border: 1px dashed #fff;
  border-color: rgba(255, 255, 255, 0.5);
  height: 40px;
}
.bk {
  background: #1199a9;
  position: absolute;
  width: 8%;
  top: 12px;
}
.bk.l {
  left: 0;
}
.bk.r {
  right: 0;
}
.skew {
  position: absolute;
  background: #0c7582;
  width: 3%;
  top: 6px;
  z-index: 5;
}
.skew.l {
  left: 5%;
  transform: skew(00deg, 20deg);
}
.skew.r {
  right: 5%;
  transform: skew(00deg, -20deg);
}
.bk.l > div {
  left: -30px;
}
.bk.r > div {
  right: -30px;
}
.arrow {
  height: 25px!important;
  position: absolute;
  z-index: 2;
  width: 0;
  height: 0;
}
.arrow.top {
  top: 0px;
  border-top: 0px solid transparent;
  border-bottom: 25px solid transparent;
  border-right: 30px solid #1199a9;
}
.arrow.bottom {
  top: 25px;
  border-top: 25px solid transparent;
  border-bottom: 0px solid transparent;
  border-right: 30px solid #1199a9;
}
.r.bottom {
  border-top: 25px solid transparent;
  border-bottom: 0px solid transparent;
  border-left: 30px solid #1199a9;
  border-right: none;
}
.r.top {
  border-bottom: 25px solid transparent;
  border-top: 0px solid transparent;
  border-left: 30px solid #1199a9;
  border-right: none;
}
@media all and (max-width: 1020px) {
  .skew.l {
    left: 5%;
    transform: skew(00deg, 25deg);
  }
  .skew.r {
    right: 5%;
    transform: skew(00deg, -25deg);
  }
}
@media all and (max-width: 680px) {
  .skew.l {
    left: 5%;
    transform: skew(00deg, 30deg);
  }
  .skew.r {
    right: 5%;
    transform: skew(00deg, -30deg);
  }
}
@media all and (max-width: 460px) {
  .skew.l {
    left: 5%;
    transform: skew(00deg, 40deg);
  }
  .skew.r {
    right: 5%;
    transform: skew(00deg, -40deg);
  }
}

<!-- RIBBON 1 --><divclass="container one"><divclass="bk l"><divclass="arrow top"></div><divclass="arrow bottom"></div></div><divclass="skew l"></div><divclass="main"><div></div></div><divclass="skew r"></div><divclass="bk r"><divclass="arrow top"></div><divclass="arrow bottom"></div></div></div>
