marquee should start from the middle?
提问by
I am using marquee to show the dashboard on my site, the marquee tag is written as:
我正在使用选取框在我的网站上显示仪表板，选取框标记写为：
<marquee loop="infinite" behavior="scroll" direction="up" scrollamount="1" height="500" width="500">
.............
.............
</marquee>
As you can see the marquee contents are scrolling from down to up.
如您所见，选取框内容正在从下向上滚动。
Problem
问题
When I hit the URL from browser, the place where marquee is used look empty and then the marquee content start coming from the bottom.
当我从浏览器点击 URL 时，使用选取框的地方看起来是空的，然后选取框内容从底部开始。
What I want is the marquee content should start from the middle rather than from the bottom.
我想要的是选取框内容应该从中间而不是从底部开始。

The <marquee>element does not have this functionality. There are some proposals to create marquees with CSS3, but those are far from definitive.
该<marquee>元素没有此功能。有一些建议使用 CSS3 创建选取框，但这些都远非最终确定。
So the only real alternative is to write one in javascript.
所以唯一真正的选择是用javascript编写一个。

This stops in the middle and starts at the middle:
这在中间停止并从中间开始：
<marquee BEHAVIOR="alternate" SCROLLAMOUNT="6" DIRECTION="down">

So when ever you use this code
所以当你使用这个代码时
<marquee loop="infinite" behavior="scroll" direction="up" scrollamount="1" height="500" width="500">
.............
.............
</marquee>
for the first block add style="margin-top:-value"so that it will starts from the middle.
对于第一个块添加，style="margin-top:-value"以便它从中间开始。

In this case. Just set the style margin-top:-500px (-height_of_marquee) of the element wrapped by marquee should work.
在这种情况下。只需设置由选取框包裹的元素的样式 margin-top:-500px (-height_of_marquee) 即可。

if you will change the attribute height of the marqee tag to 100 or something like this it wont start from the buttom
如果你将 marqee 标签的属性高度更改为 100 或类似的东西，它不会从底部开始
