opacity

I have three problems: When I tried to use a background image in a smaller size div, the div shows only part of image. How can I show the full or a specific part of image? I have a smaller image and I want to use in a bigger div. But don't want to use repeat function. Is there any way in CSS to manipulate the opacity of an image? yossi Resize the image to fit the div size. With CSS3 you can do this: /* with CSS 3 */ #yourdiv { background: url('bgimage.jpg') no-repeat; background-size: 100%; } How Do you Stretch a Background Image in a Web Page : About opacity #yourdiv { opacity: 0.4; filter:

I'm playing with the opacity CSS attribute. It works nicely for the box (with at 50% or black at 30%) - the problem is that the text inside the box is also transparent. I would like the text to be 100% white in a box with at 30% transparency. The solution is to use CSS with tweaks or to use a .png for the background and to forget the opacity setting. Tell me, how to do 30% opacity with 100% opacity text inside. Thanks in advance Your choices are: Using CSS3 : background: rgba(255, 255, 255, 0.3) .

I have two divs, both with 0.6 opacity. I need them to overlap but retain their opacity and not create a new combined opacity level. I can't use an image. EDIT -- The little circle is supposed to have a canvas element in it. Not sure if pseudo-elements would be the best solution. Is there anyway to do this with CSS, or should I just use canvas? example - http://dabblet.com/gist/1566209 HTML: <div id="foo"> <div id="bar"> </div> </div> CSS: /** * Double Opacity */ body{background:green;} #foo{ height:150px; width:250px; background:rgba(0, 0, 0, 0.6); position:absolute; left:40%; top:20%; } #bar

Find an example of how to fade out a div when the scroll bar reaches a certain position here . But it's not a smooth throttle-type fade. Here is the code from that jsfiddle: var divs = $('.social, .title'); $(window).scroll(function(){ if($(window).scrollTop()<10){ divs.fadeIn("fast"); } else { divs.fadeOut("fast"); } });​ I want the opacity percentage to to reflect the position of the scrollbar. For instance when the scroll bar is at very top position, the div opacity is 100%. When I scroll down 35px I want the opacity of the div to fade down to 0% Perhaps a technique could be when div A is

Scatter plots can be hard to interpret when many points overlap, as such overlapping obscures the density of data in a particular region. One solution is to use semi-transparent colors for the plotted points, so that opaque region indicates that many observations are present in those coordinates. Below is an example of my black and white solution in R: MyGray <- rgb(t(col2rgb("black")), alpha=50, maxColorValue=255) x1 <- rnorm(n=1E3, sd=2) x2 <- x1*1.2 + rnorm(n=1E3, sd=2) dev.new(width=3.5, height=5) par(mfrow=c(2,1), mar=c(2.5,2.5,0.5,0.5), ps=10, cex=1.15) plot(x1, x2, ylab="", xlab="", pch
