css - 文本框填充宽度，右对齐按钮等

时间：2016-12-16 15:04:04

标签： html css

在某些方面，我仍然是CSS的新手，并没有“了解”事情是如何完成的（看起来很复杂，似乎没有一种简单的方法来解决问题） - 所以我我希望有人可以帮助我。我会发布相关代码。我是一名程序员 - 但似乎无法弄清楚如何做我想做的事。 （BTW - 有没有什么好的工具可以“直观地”编辑CSS？我只是通过代码来完成这个。）

a）我需要一个HTML文本框来扩展/收缩浏览器窗口扩展/收缩，右侧有一个“搜索”图像图标。 b）我需要一些右对齐的注册/登录按钮 c）我需要左对齐的徽标/文字。

所以基本上流程是：

[＃1 logo] [＃2菜单项] [＃3带图标的搜索栏] [＃4登录/注册按钮]

如果浏览器窗口展开，则＃3会扩展以填充空格。 即，

  • 小桌面

[＃1] [＃2] [＃3] [＃4]

  • 大桌面

[＃1] [＃2]并[d＃3 --------------------------＆GT;] [＃4] < / p>

理想情况下，我还想了解移动设备（小型桌面）如何制作它：

[＃1] [＃4]

[＃3 ----＆GT;]

这是我的HTML（删除其他内容以简化）

听起来你需要明智地使用媒体查询：

@media screen and (min-width: 480px) {
    body {
        background-color: lightgreen;
    }
}

http://www.w3schools.com/cssref/css3_pr_mediaquery.asp

您已经指出了需要媒体查询的三种设备尺寸：

small desktop
[#1][#2][#3][#4]

big desktop
[#1][#2][<#3-------------------------->][#4]

mobile
[#1][#4]
[#3---->]

现在您只需要为这三种尺寸创建媒体查询并相应地设置CSS。

  • 手机：隐藏＃2。也许玩漂浮物让＃3显示在另外两个之下。
  • 大桌面：更改＃3宽度（最有可能的百分比）
  • 小桌面：＃1，＃2，＃3，＃4都应具有相同的宽度（最有可能的百分比）

然后，您可以使用width属性调整这些不同媒体宽度上按钮的大小：
