php - HTML CSS PHP 移动 div

Question

当我调整页面大小时，我的 div 一直在移动，有人可以帮我解决这个问题吗？html/php(用于登录和页面 getter 的 php)

我的 html 正文部分带有一些用于登录的 php 和页面的一些内容

<div class="menu">
    <img src="logo.png" style=" position: relative; margin-right: 38%">

    <ul class="dropdown">

        <li><a href="?page=Home" <?php if ($page == 'Home') { ?> id="a-active" <?php } ?>  >Home</a>

当我调整窗口大小时，div 会向左或向下移动。有没有一种方法可以将这些 div 设置在一个位置，使它们不会移动位置，只是停留在那里？

Answer 1

我几乎没看懂你的代码，但做了 this fiddle让您了解如何修复 div。

我建议您避免为 div 使用 float 并执行如下操作:

.fix{ 
 /* this is parent div */
    display:inline-block ;
    white-space:nowrap;
}
.fxchld{
   /* these are child divs */
    width:50px;
    display:inline-block ;
    height:50px;
    border:1px solid #000;
}

想法是使用display:inline-block ;而不是floats，这样它们就可以固定在它们的位置
否则
你必须给大的父 div 宽度，这样 child div 就不会换行

Fiddle 将帮助您理解我的观点!!
