Twitter Bootstrap sideways caret

Question

I\'m using Twitter Bootstrap and some custom css (found here) to have dropdown menus open up on mouseover.

I am using the \"caret\" on a on the root menu items to show

Answer 1

As user2661940 said you can use glyphicons for Bootstrap 3 or you can also make your own class for every side. For example

.caret-right {
  display: inline-block;
  width: 0;
  height: 0;
  margin-left: 2px;
  vertical-align: middle;
  border-left: 4px solid;
  border-bottom: 4px solid transparent;
  border-top: 4px solid transparent;
}

Answer 2

I added a rotation class to the span

HTML:

<span class="rotate270 caret"></span>

CSS:

.rotate270 {
    -webkit-transform: rotate(-90deg);
    -moz-transform: rotate(-90deg);
    -o-transform: rotate(-90deg);
    -ms-transform: rotate(-90deg);
    transform: rotate(-90deg);
}

You can obviously create other angle classes as desired.

Answer 3

Use the bootstrap (3.0) Glyphicons

<span class="glyphicon glyphicon-chevron-up"></span> <!-- UP -->
<span class="glyphicon glyphicon-chevron-down"></span> <!-- DOWN-->

Answer 4

you can use simple code:

HTML

<span class="caret"></span>

CSS:

.caret{
border-color:#ffffff transparent transparent transparent;
border-width:4px;
border-style:solid;
content: ""
display:inline-block;
}

Answer 5

I use these styles to do that (it works without bootstrap as well)

HTML:

<span class="caret up"></span>
<span class="caret right"></span>
<span class="caret down"></span>
<span class="caret left"></span>

CSS:

.caret {
    border: 5px solid transparent;
    display: inline-block;
    width: 0;
    height: 0;
    opacity: 0.5;
    vertical-align: top;
}
.caret.up {
    border-bottom: 5px solid;
}
.caret.right {
    border-left: 5px solid;
}
.caret.down {
    border-top: 5px solid;
}
.caret.left {
    border-right: 5px solid;
}

Answer 6

Just add the css to rotate the caret on mouse hover

.navbar-nav>li>.dropdown-menu{
    display:block;
    visibility:hidden;

}
.navbar-nav>li:hover>.dropdown-menu{
    visibility:visible;
}
.navbar-default .navbar-nav>li:hover>a .caret{
    transform:rotate(-90deg);
    transition:all 0.3s ease-in-out;
}
