in the control drop-down box. In this mode, the changes are made to the current drawing on
each keyframe, and the changes are not visible until the animation completes. If you
select On, the changes are made at the beginning and end of each keyframe. In the Box
Window, see Animations. The Animations window, on the Timeline panel, includes a
number of tabs that apply to all keyframes on the selected drawing: The result of the
keyframes are shown in the Box Window, and can be viewed in several ways. In this example, the
keyframes are displayed as a preview in the Box Window, and as a 3D wireframe animation in the
Timeline panel. You can create multiple keyframes on the same drawing, which makes the
animation easier to control.Q:
Is this a bug in Rails or my browser?
I'm experimenting with Rails, doing a bit of stuff to get a feel for it.
I've found some odd behavior in the browser.
I'm not sure if this is a bug in Rails or my browser.
In either case I'd like to hear from people who might know more about what's going on.
I have an image tag that's showing an icon that shows up when the page is loaded. After the page is loaded (and viewed properly), if I scroll the browser down, the icon stays put. I can scroll back up, but when I scroll down again, the icon disappears.
If I don't scroll down then the icon stays there until I scroll up.
Here's a link to the page:
As a test I put the image tag at the top of the page. When I scroll down the image stays there. If I scroll down after that, the icon disappears.
How can I get the icon to stay when the page is first displayed? It's a standard Rails app so I'm not sure if there are any "dirty" CSS tricks going on.
A:
From the looks of the source, it looks like the line-height of the image is set to 0, which is why it is always visible. If you set it to a more normal value, it will be visible.
UPDATE:
If you want to set it dynamically, you can do something like this:
@icon = "image.png"
