What is the best way to create a triangle-shaped div using CSS styling?

Seeking assistance in creating a triangular shape using CSS within a rectangular division. Grateful for any guidance provided.

Answer №1

It seems the question may not be completely clear, but if you're looking to create a small triangle, using borders would be the way to go.

If you'd like more information on this topic, please refer to http://css-tricks.com/examples/ShapesOfCSS/

Your div container should include standard properties such as background color, padding, etc., and should also have a relative position. To create the triangle, you can add the following CSS:

div:after {
  content: "";
  position: absolute;
  left: -100px; /* adjust based on desired triangle width */
  top: 0;
  height: 0;
  border-top: 50px solid transparent; /* half of the div's height */
  border-left: 100px solid red; /* triangle width + background color */
  border-bottom: 50px solid transparent; /* half of the div's height */
  width: 0;
}

I hope I've covered everything for you!

To change the size of the right side triangle, simply adjust the border-left property.

.container{display:block;width:500px;height:300px;background:#f9f9f9;}
.rectangle{height:55px;width:250px;background:#ccc;display:table;line-height:50px;text-indent:50px;}
.green{background-color:#6ed2ac;}
.tip{float:left;color:#fff;}
.check{content:'';border:2px solid rgba(255,255,255,0.85);position:absolute;width:14px;margin:17px 0 0 17px;text-indent:0px;color:#fff;line-height:14px;height:14px;}
#triangle{float:left;width:0px;height:5px;border-top:25px solid transparent;border-left:10px solid #6ed2ac;border-bottom:25px solid transparent;}

<div class="container">
    <div class="rectangle">Explore New Features</div>
    <div class="rectangle green tip">
        <div class="check">✔</div>

        <div id="triangle"></div>
    </div>
    <div class="rectangle">Customize Your Experience</div>

  width: 15em;
  height: 6em;
  background: lightPink;
}
section:before {
  content: "";
  position: absolute;
  top: 0;
  right: -2em;
  width: 0;
  height: 0;
  border-bottom: 3em solid transparent;
  border-top: 3em solid transparent;
  border-left: 1.5em solid lightPink;
}

Answer №4

Even though the previous examples featured right angle triangles, I wanted to share a method for creating triangles with less sharp angles:

Try using this CSS code snippet:

.triangle::after{
    content: "";
    position:absolute;
    right:-10px;
    width: 0;
    height: 0;
    border-style: solid;
    border-width: 30px 0 30px 10px;
    border-color: transparent transparent transparent #6ed2ad;
}

.triangle{
    position:relative;
    background:#6ed2ad;
    height:60px;
    line-height:60px;
    color:#fff;
    padding:0 30px;
    display:inline-block;
}
