二次元风格的登录界面，也只是用html和css来写的，大家可以来看看！

给大家带来比较具有二次元风格的登录界面，也只是用html和css来写的，大家可以来看看！

HTML部分

既然是制作登录界面我们可以使用表单元素，会比盒子更加简单一些，个人相信大家应该可以明白里头的啥意思吧！！！

这边就介绍一下CSS部分吧

<div class="shell">
        <div id="img-box">
            <img src="./a34a7810c48ee409750f92812023beb0-1.jpg" alt="">
        </div>
        <form action="" method="post">
            <div id="form-body">
                <div id="welcome-lines">
                    <div id="w-line-1">HI,老K</div>
                    <div id="w-line-2">Welcome Back</div>
                </div>
                <div id="input-area">
                    <div class="f-inp">
                        <input type="text" placeholder="Email Address">
                    </div>
                    <div class="f-inp">
                        <input type="password" placeholder="Password">
                    </div>
                </div>
                <div id="submit-button-cvr">
                    <button type="submit" id="submit-button">LOGIN</button>
                </div>
                <div id="forgot-pass">
                    <a href="#">Forgot password?</a>
                </div>
            </div>
        </form>
    </div>...

CSS部分

还是给我们先清除内外边距

然后这个ountline：none；的意思是鼠标点击文本框的时候，文本的边框焦点会被去除掉

还是设置一个背景颜色，这里我们使用的是渐变色：然后在需要让盒子来正中间，需要使用弹性布局

感觉下面都挺简单的，我就着重讲一下这个伪元素吧placeholder

placeholder 是HTML5 中新增的一个属性。placeholder可以用来描述输入字段预期值的简短的提示信息。提示信息会在用户输入值之前显示，一旦用户输入信息该提示就会自动消失。比如：我们在登录时需要输入用户名和密码，它会提示你什么地方输入用户名，什么地方输入密码，这个就是使用的placeholder属性。
