Detailed explanation of sample code sharing using HTML5+css3 to achieve running hearts and dynamic water drop effects

The wind is blowing, the clouds are flying, and the warriors are marching in all directions! HTML5+css3, you can’t do it without learning. I have been doing web development for several years and have witnessed the rise and fall of many languages. In fact, the most difficult thing as a programmer is to keep catching up with new frameworks and languages ​​​​from major companies every day (the first to bear the brunt of this are .net programmers. Of course, unfortunately, I am a .net member. This has just happened. mvc 4.0 is fully understood and now 5.0 is out.) Of course, complaining can't solve any problems, and complaining can't make your wallet bigger. So, programmers, keep learning.

The html5+css3 era, referred to as the 3+5 era (3+5 was made up by me, without any basis - -) has obviously come overwhelmingly. On October 29, 2014, the World Wide Web Consortium announced that, After nearly 8 years of hard work, the standard specification was finally completed. This means that we should learn quickly again, otherwise we will become Ultraman again. In fact, I started to come into contact with html5 a long time ago.

When I write this blog, I don’t want to talk about the difference between html5 and html4. I think many people have already done this work. I just demo it here based on my own hobbies and project needs.

　Code effect: ps: If the water drop effect cannot be displayed, you can download the source code below.

　Html part:

<!--爱心-->
        <div class="heart" id="heart"></div>
        <!--左边的箭头-->
        <span class="arrow arrow-down"></span>
        <!--右边的箭头-->
        <span class="arrow arrow-down" style="margin-left:152px;"></span>
        <!--水滴效果-->
        <div class="">
            <span class="water" style="margin-left:10px;"></span>
            <span class="water" style="margin-left:200px;"></span>
            <span class="water" style="margin-left:50px;"></span>
            <!--原文出自 博客园 请叫我头头哥： www.cnblogs.com/toutou-->
            <span class="water" style="margin-left:120px;"></span>
            <span class="water" style="margin-left:30px;"></span>
            <span class="water" style="margin-left:170px;"></span>
            <span class="water" style="margin-left:200px;"></span>
        </div>

　css part: ps: I have added comments on some core properties in css3. If you don’t understand anything, you can message. In addition, a lot of this content (similar to "Original text comes from...") has been added to the code. I believe everyone understands that this is to prevent malicious crawling and plagiarism! Support genuine :)
