① C# web页面 浮动控件如何做
放到DIV里面，然后设置DIV的style="position:fixed;top:0px;left:0px"是放在左上
style="position:fixed;bottom:0px;right:0px"是放在右下
② Web页面的浮动咨询，如何改里面的文字 如：首页中的一个浮动咨询小页面，要改里面的某些文字，怎么改
有两种实现方式：
1、直接坐在图片上
2、把图片上的文字处理掉；通过css来处理
③ 如何设置在网页中浮动的层

⑤ Web前端基础】css中浮动属性有什么
float right none(不浮动) inherit从父元素继承浮动的属性值
⑥ web网页设计,html语言。浮动float和定位position的问题。谢谢！ 问题1:做了
外面嵌套一个DIV 让position随着父层DIV而定位 而不是随着浏览器的左上角而定位
⑦ html中浮动窗口怎么做啊就是一个小窗口飘在在页面上那种
需要浮动的话，只需要在样式上的position设置fixed即可。
比如：
<div style="position:fixed; z-index:1;">
</div>
这样写就浮动了，然后只需要用top、bottom、left、right来定位就行了
如果需要飘来飘去的浮动，需要配合js来完成，js可以去牛图库上找，里面有很多插件，改下样式就可以使用了。
⑧ web前端什么是浮动定位
float:left | right
⑨ web前端如果父级和子级都加了浮动会有什么现象
在WEB前端当中，如果针对元素进行了浮动的设置，则该元素会脱离文档流而存在，会引起父级元素的塌陷，同时会对同一级别的元素造成布局上的影响。
但是，当为父级元素也设置了浮动之后，父级元素也脱离文档流，父级元素和子级元素都属于浮动元素，此时，父级元素高度塌陷的问题反而会被解决（即：另一个元素的父级元素浮动，是针对该子级元素清浮动的一种方法），但是由于父级元素发生浮动，父级元素的兄弟级元素以及父级元素的父级元素，依旧会受到布局的影响。
如果是清除浮动，可以使用多种方法来实现，最为推荐的其实是after伪元素清浮动，会更好用，也是当前WEB前端开发当中最为主流的一种清除浮动方法
⑩ 怎样把UCWEB右上角经常浮动的提示关掉
菜单—设置—系统设置—下载设置（右移两下）—任务开始提示（上移两下）—欧了……
