移动问题，修改引导类或错误的媒体查询

Posted 2023-03-06

技术标签:

【中文标题】移动问题，修改引导类或错误的媒体查询【英文标题】：Mobile issue , Modify Bootstrap classes or wrong media query 【发布时间】：2019-07-09 21:45:05 【问题描述】：

如您所见，我的媒体查询变得一团糟。我正在用项目符号创建这个时间线，发现自己写了太多媒体查询，试图让项目符号与时间线对齐

我非常相信我在某个地方犯了错误。在非媒体查询的 css 部分中，可能在位置绝对区域中。我只是无法确定对齐方式。我的要求不是任何特定的屏幕尺寸，因此，我必须使其在所有屏幕尺寸上都能发挥最佳效果，我正在通过使浏览器宽度越来越小来进行测试。有对此的引导解决方案吗？我是否以错误的方式编写媒体查询？

我是 CSS 和移动方面的初学者，这是我目前的代码

【问题讨论】：

你可以关注这个link 【参考方案1】：

看看这个方法：https://www.bootply.com/KBKYt3w6Z7

基本上，如果您可以调整标记以使 :before 和 :after 位于同一元素上，则您的时间轴不需要所有这些媒体查询，然后您可以将行和红点定位在相同的位置/级别。

在示例中，我已将您的标记更改为使用 ul > li，并将其更改为时间轴 CSS 位于列表项上。

HTH

【讨论】：

【参考方案2】：

用最少的努力，

https://stackblitz.com/edit/js-lvgwcp?file=style.css

我已经删除了所有的 CSS，只得到了我想要的时间线。所以为你的项目添加你需要的任何东西。这是对最小 360px 宽度设备的响应。

我还做了一些html修改，就是我添加了<div class="project-content">这个div。

无媒体查询。

如有任何澄清意见，请。

同样没有任何用户界面，我将项目符号与时间线分开。如果需要，可以与 css left 属性对齐。

【讨论】：

【参考方案3】：

答案很简单，我删除了所有媒体查询并使用 px 而不是 % on
