This time I will bring you the left and right swing ads on the front-end page. What are the precautions for realizing the left and right swing ads on the front-end page? Here is a practical case, let’s take a look.

Code Interpretation

Define dom, the container contains a bulletin board, a string to hang the bulletin board and 3 push pins to fix the rope:

<p class="signboard">
    <p class="sign">THANKS</p>
    <p class="strings"></p>
    <p class="pin top"></p>
    <p class="pin left"></p>
    <p class="pin right"></p>
</p>

Centered display:

html, body {
    width: 100%;
    height: 100%;
    display: flex;
    align-items: center;
    justify-content: center;
    background: radial-gradient(circle at center 60%, white, sandybrown);
}

Copy after login

Define the overall size of the bulletin board:

.signboard {
    width: 400px;
    height: 300px;
}

Copy after login

Set the style of the board:

.signboard {
    position: relative;
}
.sign {
    width: 100%;
    height: 200px;
    background: burlywood;
    border-radius: 15px;
    position: absolute;
    bottom: 0;
}

Copy after login

Set the text style with engraving effect:

.sign {
    color: saddlebrown;
    font-family: sans-serif;
    font-weight: bold;
    text-align: center;
    line-height: 200px;
    text-shadow: 0 2px 0 rgba(255, 255, 255, 0.3),
                0 -2px 0 rgba(0, 0, 0, 0.7);
}

Copy after login

Draw the string:

.strings {
    width: 150px;
    height: 150px;
    border: 5px solid brown;
    position: absolute;
    border-right: none;
    border-bottom: none;
    transform: rotate(45deg);
    top: 38px;
    left: 122px;
}

Copy after login

Draw the thumbtacks on the top of the string:

.pin {
    width: 25px;
    height: 25px;
    border-radius: 50%;
    position: absolute;
}
.pin.top {
    background: gray;
    left: 187px;
}

Copy after login

Draw the thumbtacks on the left and right sides of the board:

.pin.left,
.pin.right {
    background: brown;
    top: 110px;
    box-shadow: 0 2px 0 rgba(255, 255, 255, 0.3);
}
.pin.left {
    left: 80px;
}
.pin.right {
    right: 80px;
}

Copy after login

Finally, make the sign shake:
(This has been modified according to Xiao Leilei's suggestion to use the top pushpin as the axis of rotation, which is better than the original effect)

.signboard {
    animation: swing 1.5s ease-in-out infinite alternate;
    transform-origin: 200px 13px;
}
@keyframes swing {
    from {
        transform: rotate(10deg);
    }
    to {
        transform: rotate(-10deg);
    }
}

Copy after login

Done!
