css-transforms

I have a div that is positioned absolute with a background color gradient. I have this text on it that I want to change to the color white as I scroll the text up. I'm using the 'mix-blend-mode' property to achieve this currently but I can't find any setting that will turn the text from black to white. Has anyone done this before or can think of a trick I can do? .bg-container { position: fixed; top: -30px; left: 0; width: 100px; height: 100px; } .gradient-background { position: absolute; top: 0; left: 0; width: 100px; height: 200px; background-image: linear-gradient(to bottom, rgb(100, 182,

I've been trying for the last few hours to figure out how come a child element was positioning against its parent and not the screenport even though it's positioned as 'fixed'. Very luckily, I stumbled across the mentioning that -webkit-transform: translate3d(0, 0, 0) on the parent can make things go awry. I'm using bootstrap framework and so they indeed put this property on the .navbar-fixed-top class which one of parent elements had. Once I removed it the child started to position agains viewport. So I have two questions: Why does -webkit-transform: translate3d(0, 0, 0) do these nasty things

I have the following mixin for cross-browser transform: .transform (...) { -webkit-transform: @arguments; /* Chrome, Opera 15+, Safari 3.1+ */ -moz-transform: @arguments; /* Firefox 3.5+ */ -ms-transform: @arguments; /* IE 9 */ -o-transform: @arguments; /* Opera 10.5+ */ transform: @arguments; /* Firefox 16+, IE 10+, Opera */ } .translate(@x:0, @y:0) { .transform(translate(@x, @y)); } And apply it something like the following: #main { .translate(280px, 0); } But it's not wotk in IE8 and Opera mini . Is there some fallback, polyfill or any for supporting it in therese browsers? There are a few

I am trying to make the below shape using only CSS. I know that achieving this shape using an image or SVG would be a lot easier but I am trying to achieve it with CSS for a proof of concept. The below is the code that I have tried so far. It creates a diamond shape by using transform: rotate(45deg) but the diagonals are of the same length whereas the shape that I need has one very long diagonal and another very short. .separator{ background: #555; top: 40px; padding-top: 0px; margin: 0px 40px; height: 100px; width: 100px; -webkit-transform: rotate(45deg); -moz-transform: rotate(45deg);

I have trying to create a 3D sphere using just pure css, but I've been unable to generate the shape required. I've seen a cylinder but I can't find any reference to creating an actual sphere . My current code looks like: .red { background-color: red; } .green { background-color: green; } .blue { background-color: blue; } .yellow { background-color: yellow; } .sphere { height: 200px; width: 200px; border-radius: 50%; text-align: center; vertical-align: middle; font-size: 500%; position: relative; box-shadow: inset -10px -10px 100px #000, 10px 10px 20px black, inset 0px 0px 10px black; display:
