前言

我想为庆祝祖国干点事情，就写了这个小国 旗，再加上【北京欢迎你】这首歌的搭配，非常有韵味！

效果图

附上代码

css代码

[ttlogin]

<style>
  .content {
    flex-grow: 1;
}

.flagpole-container {
    position: fixed;
    bottom: 0;
    left: 50%;
    transform: translateX(-50%);
    z-index: 1000;
}

.flagpole {
    width: 4px;
    height: 200px;
    background-color: #888;
    position: relative;
}

.flagpole .flag {
    width: 80px !important;
    height: 50px !important;
    position: absolute;
    bottom: 0;
    left: 4px;
    transform-origin: left center;
    animation: flag-raise 10s ease-out forwards;
    object-fit: cover !important;
    max-width: none !important;
    max-height: none !important;
}

@keyframes flag-raise {
    0% {
        transform: translateY(100%);
    }
    100% {
        transform: translateY(calc(-100% - 97px));
    }
}
</style>

这个放网页底部

<div class="flagpole-container"> 
<div class="flagpole"> <img src="https://wimg.588ku.com/gif620/20/09/10/5fc63bcbe18e3631fbf8ddf2b995bade.gif" alt="飘动" class="flag"> </div> </div>
