Question

我正在尝试使用用户名和密码在登录表单下对齐，左侧的复选框是“还记得我吗？”右边是一个Login按钮，但是我无法弄清楚如何正确对齐它们。当前它们不在所需位置并且看起来很糟糕复选框和登录按钮的代码位于css的末尾-label.custom-checkbox和.loginbutton

My desired result is something like this :https://imgur.com/a/ICeuVUM

Answer 1

在第一个

label.custom-checkbox input[type="checkbox"] {
    /* float: left; */
    /* opacity: 0; */
    display: none;
}

.custom-checkbox{
    float:left;
}

并将类添加到“登录”按钮中，说出login-btn以添加宽度，如下所示：

.login-btn{
    width: 30%;
}

这是结果：

好的，我在您的代码中更改了一些样式。我建议您在要对齐内容时应使用flex-box，并尝试使用更多的div来包装元素。避免过度使用重要的东西。您可以按照下面的代码结构进行操作。它的响应速度也很完美。希望能有所帮助：）

    margin: 0px;
    padding: 0px;
