fixed

问题 I'm trying to set a background image for an spn web app and I need the background to be fixed (that it won't be scrolled with the rest of the page). this is the body css: body { background-color: rgb(51, 102, 102); background-image: url('../images/background.png'); background-attachment: fixed; background-position: center; color: #eee; } Safari in IOS and Chrome on Android repeat the background instead of fixing it at one point. I've seen on the internet it's been disabled on mobile but is

问题 Say I have a plot like this: library(ggplot2) dat <- data.frame(x = 1:10, y = 1:10) ggplot(dat, aes(x = x, y = y)) + geom_point() + xlab("Test label") Does ggplot2 allow for fixing the xlab positioning at a specific point? Say I wanted the label to appear centered at the point where x = 7 (rather than the default centering). 回答1: This isn't exactly what you want, but you can adjust the horizontal justification in the theme options. This is relative between 0 and 1, not tied to the data

问题 I tested the keyword fixed with array and string variables and worked really well but I can't use with a single variable. static void Main() { int value = 12345; unsafe { fixed (int* pValue = &value) { // problem here *pValue = 54321; } } } The line fixed (int* pValue = &value) causes a complier error. I don't get it because the variable value is out of the unsafe block and it is not pinned yet. Why can't I use fixed for the variable value ? 回答1: This is because value is a local variable,

问题 I am curious to know how to create a background image in a div that is fixed. When you scroll down (or up) the image stays but the content flows over the div. Here is a site that does what I am trying to explain, to give you a better idea on what I am trying to describe. jWebMedia I've always thought sites like this were really attractive and wanted to know how to develop it. If you know of any good articles that cover this, that would be great. Thanks for all your help! 回答1: background:url(

问题 My situation is that I have fixed position div with percented height at the bottom of page that is on top of it(see picture). The issue is that when I scroll page to the end, some of its content is hidden beneath this div. I think I should add empty element at the bottom of page, but what is the best way to do it? 回答1: A nice solution could be to change the height of the fixed div to be expressed in vh not in % (see), for example: div.fixed-at-bottom { height: 20vh; .... } and then set a

问题 I'm having a hard time aligning decimal values. I am pretty sure its a combination of right alignment and setprecision/fixed but it doesn't seem to be working. I know other questions have been asked on the topic but I haven't found a clear solution to getting a bunch of columns (unique cout statements to align). This is a chunk of my code: double total_collect, sales, country_tax, state_tax, total_tax; const double STATE_TAX_RATE = 0.04, COUNTRY_TAX_RATE = 0.02; // Compute taxes total_collect

问题 i found interesting feature, but cant find why it happens. So: We have fixed position element, which second under body. First element have styles .firstEl { width:100%; height:200px; background-color:green; } Second element have .fixedEl { position:fixed; right:0; height:100px; width:50px; background-color:red; } Where do you think will be fixed element positioning by top? It`s intresting behavior when js change height of first element and our fixed container change his position too. https:/
