In web pages, in order to highlight the theme of their products, designers usually make text or add some special effects, such as making the text flash continuously or change color regularly. In order to achieve the purpose of attracting attention. So in addition to GIF animations produced with PS, what other methods can be used to achieve such special effects? For those who know a little bit about code, we all know that there are many types of Chinese font styles in CSS, such as italic, bold, etc. So here I will introduce to you how to use css code to create a text flashing effect. There are two flashing methods in this article for your reference.

1. The specific sample code for css font flashing (wave flashing) is as follows:

    <style>
        body{
            background: #000;
        }
        h1.fb-glitch {
            position: relative;
            color: #abff79;
        }
        h1.fb-glitch:before {
            left: -2px;
            text-shadow: 2px 0 #0b391a;
            animation: glitch-anim-2 3s infinite linear alternate-reverse;
        }
        h1.fb-glitch:before, h1.fb-glitch:after {
