      .snowfall-flakes:before {
            -webkit-transform: rotate(-45deg);
            /* Safari 和 Chrome */
            -moz-transform: rotate(-45deg);
            /* Firefox */
            -ms-transform: rotate(-45deg);
            /* IE 9 */
            -o-transform: rotate(-45deg);
            /* Opera */
            transform: rotate(-45deg);
        }
        .snowfall-flakes:after {
            -webkit-transform: rotate(45deg);
            /* Safari 和 Chrome */
            -moz-transform: rotate(45deg);
            /* Firefox */
            -ms-transform: rotate(45deg);
            /* IE 9 */
            -o-transform: rotate(45deg);
            /* Opera */
            transform: rotate(45deg);
        }

Step 3:

Use the

left attribute to offset the pseudo element after by a certain pixel to the left, so that the two micro elements partially overlap to form a heart It looks like, as shown in the picture:

      .snowfall-flakes:after {
            left: 13px;
            -webkit-transform: rotate(45deg);
            /* Safari 和 Chrome */
            -moz-transform: rotate(45deg);
            /* Firefox */
            -ms-transform: rotate(45deg);
            /* IE 9 */
            -o-transform: rotate(45deg);
            /* Opera */
            transform: rotate(45deg);
        }

We have finished drawing the love, so how to make the love fly all over the screen? In fact, we only need to call jquery.js and snowfall.jquery. js can be achieved, and the rendering is as follows:

In fact, I personally think that smaller love paintings look better , the purpose of drawing it so big above is to make it easier for everyone to see the love more clearly. The rendering after drawing the love smaller is as follows:

For small hearts, the following attributes need to be changed. Value:

        .snowfall-flakes:before,
        .snowfall-flakes:after {
            width: 10px;
            height: 16px;
            border-radius: 10px 10px 0 0;
        }
        .snowfall-flakes:after {
            left: 4px;
        }
