Question

我的导航栏有问题。我希望“注册”按钮位于“登录”按钮的右侧，与窗口右边缘之间的间隔为xxxpx，这样当您将鼠标悬停在“登录”按钮上时，带有输入不会出现在屏幕上。我试图将“注册”按钮放在“”中，但是由于CSS代码，即使在“注册”按钮上悬停了鼠标也不是我期望的行为，但我还是获得了登录表单。如何将“注册”按钮放在“登录”按钮的右侧？附言这是用于anguar的代码，但功能相同。谢谢。

Answer 1

只需将“注册”按钮的锚标记放置在“下拉”区域上方。

<div class="topnav" id="myTopnav">
     <a routerLink="/" class="active">Home</a>
     <a routerLink="/gallery">Gallery</a>
  <a style="float:right" routerLink="/register">Register</a>
     <div class="dropdown">
         <button class="dropbtn-login">Login</button>
         <div class="dropdown-content-login">
             <form>
                <input class="forminput" placeholder="username">
                <input class="forminput" type="password" placeholder="password">
                <button class="formbutton" type="submit">Login</button>
            </form>
        </div>
    </div>

    <div style="float:right" class="space"></div>
    <a href="" class="icon" (click)="myFunction()">&#9776;</a>
</div>
