How to create a heart shape using CSS?

A new idea with less of code:

.heart {
  display:inline-block;
  width: 200px; 
  aspect-ratio: 1;
  border-image: radial-gradient(red 69%,#0000 70%) 84.5% fill/100%;
  clip-path: polygon(-41% 0,50% 91%, 141% 0);
}
<div class="heart"></div>
<div class="heart" style="width:100px"></div>
<div class="heart" style="width:50px"></div>

Using mask, we can apply it to an image:

img {
  width: 200px;
  aspect-ratio: 1;
  object-fit: cover;
  --_m: radial-gradient(#000 69%,#0000 70%) 84.5% fill/100%;
  -webkit-mask-box-image: var(--_m);
             mask-border: var(--_m);
  clip-path: polygon(-41% 0,50% 91%, 141% 0);
}

/* fallback until better support for mask-border */
@supports not (-webkit-mask-box-image: var(--_m)) { 
  img {
   --_m:
     radial-gradient(circle at 60% 63%,#000 64%,#0000 65%) top left /50% 50% no-repeat,
     radial-gradient(circle at 40% 63%,#000 64%,#0000 65%) top right/50% 50% no-repeat,
     linear-gradient(#000 0 0) bottom/100% 50% no-repeat;
   -webkit-mask: var(--_m);
           mask: var(--_m);
  }
}

body {
  margin: 0;
  min-height: 100vh;
  display: grid;
  grid-auto-flow: column;
  place-content: center;
  gap: 30px;
  background: pink;
  filter: drop-shadow(0 0 10px #ff3e60)
}
<img src="https://picsum.photos/id/1027/300/300"  alt="the face of a beautiful girl">
<img src="https://picsum.photos/id/64/300/300"  alt="another beautiful girl">

Here is another idea using one element and relying on multiple backgrounds to achieve the heart shape. You can also easily adjust the size by only changing the width:

.heart {
  width:200px;
  background:
   radial-gradient(circle at 60% 65%, red 64%, transparent 65%) top left,
   radial-gradient(circle at 40% 65%, red 64%, transparent 65%) top right,
   linear-gradient(to bottom left, red 43%,transparent 43%) bottom left ,
   linear-gradient(to bottom right,red 43%,transparent 43%) bottom right;
  background-size:50% 50%;
  background-repeat:no-repeat;
  display:inline-block;
}
.heart::before {
  content:"";
  display:block;
  padding-top:100%;
}
<div class="heart">
</div>
<div class="heart" style="width:100px">
</div>
<div class="heart" style="width:60px">
</div>
<div class="heart" style="width:30px">
</div>

CSS heart shape

You can also use mask and you can have any kind of coloration:

.heart {
  width:200px;
  display:inline-block;
  -webkit-mask:
     radial-gradient(circle at 60% 65%, red 64%, transparent 65%) top left,
     radial-gradient(circle at 40% 65%, red 64%, transparent 65%) top right,
     linear-gradient(to bottom left, red 43%,transparent 43%) bottom left ,
     linear-gradient(to bottom right,red 43%,transparent 43%) bottom right;
  -webkit-mask-size:50% 50%;
  -webkit-mask-repeat:no-repeat;
  mask:
     radial-gradient(circle at 60% 65%, red 64%, transparent 65%) top left,
     radial-gradient(circle at 40% 65%, red 64%, transparent 65%) top right,
     linear-gradient(to bottom left, red 43%,transparent 43%) bottom left ,
     linear-gradient(to bottom right,red 43%,transparent 43%) bottom right;
  mask-size:50% 50%;
  mask-repeat:no-repeat;
  background:linear-gradient(red,blue);
}
.heart::before {
  content:"";
  display:block;
  padding-top:100%;
}
<div class="heart">
</div>
<div class="heart" style="width:100px;background:linear-gradient(45deg,grey 50%,purple 0)">
</div>
<div class="heart" style="width:60px;background:radial-gradient(red,yellow,red)">
</div>
<div class="heart" style="width:30px;background:blue">
</div>

CSS heart shape with gradient coloration


How does it works?

The whole shape is combined using 4 gradients: 2 gradients to create the top part and 2 for the bottom parts. each gradient is taking 1/4 of size and placed at a corner.

Use a different color for each gradient to clearly identify the puzzle

.heart {
  width:200px;
  background:
   radial-gradient(circle at 60% 65%, red  64%, grey 65%) top left,
   radial-gradient(circle at 40% 65%, blue 64%, black 65%) top right,
   linear-gradient(to bottom left, green 43%,black 43%) bottom left ,
   linear-gradient(to bottom right,purple 43%,grey 43%) bottom right;
  background-size:50% 50%;
  background-repeat:no-repeat;
  display:inline-block;
  border:5px solid yellow;
}
.heart::before {
  content:"";
  display:block;
  padding-top:100%;
}
<div class="heart">
</div>

CSS3 Mon Amour - A 4 Step Love Afair

There are a few steps for creating heart shape using CSS3:

  1. Create a block-level element such as a <div> in your DOM and assign it with id="heart" and apply CSS:

    #heart {
     position:relative; 
     width:100px; 
     height:90px;
     margin-top:10px; /* leave some space above */
}

  2. Now using pseudo-element #heart:before we create a red box with one rounded edge like this:

    #heart:before {
    position: absolute; 
    content: ""; 
    left: 50px; 
    top: 0; 
    width: 52px; 
    height: 80px; 
    background: red; /* assign a nice red color */
    border-radius: 50px 50px 0 0; /* make the top edge round */ 
}

    Your heart should now look like this:

    enter image description here

  3. Let us assign a little rotation to that by adding:

    #heart:before {
    -webkit-transform: rotate(-45deg); /* 45 degrees rotation counter clockwise */
       -moz-transform: rotate(-45deg); 
        -ms-transform: rotate(-45deg); 
         -o-transform: rotate(-45deg); 
            transform: rotate(-45deg); 
    -webkit-transform-origin: 0 100%; /* Rotate it around the bottom-left corner */
       -moz-transform-origin: 0 100%; 
        -ms-transform-origin: 0 100%; 
         -o-transform-origin: 0 100%; 
            transform-origin: 0 100%;
}

    And we now get:

    enter image description here

    Already starting to come together :).

  4. Now for the right part we basically need the same shape only rotated 45 degrees clockwise instead of counter clockwise. To avoid code duplication we attach the css of #heart:before also to #heart:after, and then apply the change in position and in angle:

    #heart:after { 
    left: 0; /* placing the right part properly */
    -webkit-transform: rotate(45deg); /* rotating 45 degrees clockwise */
       -moz-transform: rotate(45deg); 
        -ms-transform: rotate(45deg); 
         -o-transform: rotate(45deg); 
            transform: rotate(45deg); 
    -webkit-transform-origin: 100% 100%; /* rotation is around bottom-right corner this time */
       -moz-transform-origin: 100% 100%; 
        -ms-transform-origin: 100% 100%; 
         -o-transform-origin: 100% 100%; 
            transform-origin :100% 100%; 
}

    And voilà! a complete heart shaped <div>:

    enter image description here

Snippet without any prefix:

#heart {
  position: relative;
  width: 100px;
  height: 90px;
  margin-top: 10px;
}

#heart::before, #heart::after {
  content: "";
  position: absolute;
  top: 0;
  width: 52px;
  height: 80px;
  border-radius: 50px 50px 0 0;
  background: red;
}

#heart::before {
  left: 50px;
  transform: rotate(-45deg);
  transform-origin: 0 100%;
}

#heart::after {
  left: 0;
  transform: rotate(45deg);
  transform-origin: 100% 100%;
}
<div id="heart"></div>
