how to create arrow down/up in css

Question

How can I create a arrow point down /up in css?

I tried to build it from div:

.triangle_down {
    width: 0;
    height: 0;
    border-left: 15px solid transparent;
    border-right: 15px solid transparent;
    border-top: 15px solid #2f2f2f;
    font-size: 0;
    line-height: 0;
    float: left;
}

This is the result: .

But i tried to build something like this:

Any suggestions?

Answer 1

If you don't want to use icons you can use ::before and ::after pseudo-class.

This is one of the various way you can get an arrow in pure CSS.

HTML

<div class="arrow"></div>

CSS

.arrow {
  position: absolute;
  top: 20px;
  left: 20px;
}

.arrow::before,
.arrow::after {
  position: relative;
  content: '';
  display: block;
  width: 20px;
  height: 1px;
  background: #000;
}

.arrow::before {
  transform: rotate(45deg);
}

.arrow::after {
  left: 14px;
  transform: rotate(-45deg);
}

My proposal is:

 .triangle_down { width: 0; height: 0; border-left: 15px solid transparent; border-right: 15px solid transparent; border-top: 15px solid #2f2f2f; font-size: 0; line-height: 0; float: left; } .triangle_down1 { position: relative; top: -5px; content: ""; display: inline-block; width: 15px; height: 15px; border-right: 0.2em solid black; border-top: 0.2em solid black; transform: rotate(135deg); margin-right: 0.5em; margin-left: 1.0em; } .triangle_up1 { position: relative; top: -5px; content: ""; display: inline-block; width: 15px; height: 15px; border-right: 0.2em solid black; border-top: 0.2em solid black; transform: rotate(-45deg); margin-right: 0.5em; margin-left: 1.0em; } 

 <div id="dialog1" class="triangle_down"></div> <div id="dialog2" class="triangle_down1"></div> <div id="dialog3" class="triangle_up1"></div> 

Answer 3

What you want is a chevron, not an arrow. Pure CSS solution:

.chevron::before {
    border-style: solid;
    border-width: 0.15em 0.15em 0 0;
    content: '';
    display: inline-block;
    height: 0.45em;
    left: 0.15em;
    top: 0.15em;
    vertical-align: top;
    width: 0.45em;
    transform: rotate(135deg);
}

 #uparrow:before { content: '\\276F'; } #downarrow:before { content: '\\276E'; } #uparrow, #downarrow { font-size: 30px; display: inline-block; -ms-transform: rotate(90deg); -webkit-transform: rotate(90deg); transform: rotate(90deg); padding: 10px; } 

 <span id="uparrow"></span><span id="downarrow"></span> 

You can include unicode characters like that, which are used by pretty much any system nowadays. Check out how it looks here: https://jsfiddle.net/mcdbu2pj/2/

Simply find the correct unicode characters you want. It won't matter which direction they're in, as you can just rotate them (like I did). Remember to set their display property to inline-block !

Answer 5

Depending on the type of arrow you need, there is a very simple approach using HTML symbol codes. For instance I used ↑ for an arrow pointing upwards. I found it here HTML Symbols

Answer 6

As simple as it gets:

.up,
.down {
    content: "";
    width: 10px;
    height: 10px;
    border: solid black;
    border-width: 1px 1px 0 0;
}
.up {
    transform: rotate(-45deg);
}
.down {
   transform: rotate(135deg);
}

Don't forget:

<div class="up"></div>
<div class="down"></div>
