Make triangle animation stretch instead of move - html

I would like the moving overlay triangle in this fiddle to stretch its animation to fit the forest image. The problem as you see now is that it creates whitespace at the top and its moving the triangle instead of stretching it. If anyone got a smart solution please comment.
i tried modifying these values but can't get it working properly.
border-left: 47.5vw solid transparent;
border-right: 47.5vw solid transparent;
border-top: 95vh solid rgba(255, 255, 255, 0.2);

It doesn't work, because you have 95vw (2x 47.5) width of border(left/right), 95vh of border top and you just move it down with translate. I think that better way is to manipulate border-width in animation
#keyframes bounce {
0%, 20%, 50%, 80%, 100% {
border-left-width: 47.5vw;
border-right-width: 47.5vw;
left: 2.5vw;
border-top-width:95vh;
top: -5vh;
}
40% {
border-left-width: 50vw;
border-right-width: 50vw;
left: 0;
border-top-width: 100vh;
top: 0vh;
}
}

Just change the "bounce" animation. Add scale property.
.bounce {
-webkit-animation-name: bounce;
animation-name: bounce;
}
#-webkit-keyframes bounce {
0%, 20%, 50%, 80%, 100% {
-webkit-transform: translateY(0) scale(1);
}
40% {
-webkit-transform: translateY(10vh) scale(2);
}
}
#keyframes bounce {
0%, 20%, 50%, 80%, 100% {
transform: translateY(0) scale(1);
}
40% {
transform: translateY(10vh) scale(2);
}
}

CSS Marquee With Fade In/Out Effect

I am trying to make a CSS marquee whose text fades in from the right edge and fades out on the left edge. Only the letters on the edges should turn transparent. I'd call it an "opacity mask" that is feathered onto the left/right edges.
I can find CSS marquee code samples but none with such a fade in/out effect. I'd also like the background to be completely transparent, with just the text having the edge effects.
I've tried adding a gradient to the container but, in hind sight, that doesn't seem to be the right path. Below is the code I've come up with thus far. Please assist, thanks!
#Bernard Borg: I've updated my code with the second new sample. Other than this not using opacity - and therefore being A) dependent on being hardcoded to the underlying background color and B) only working on a solid background - this is acceptable for my use case. Thanks! (Any idea how to cover the marquee with opacity rather than a color?)

For some reason backdrop-filter (specifically with opacity) isn't doing anything. Weird.
Edit:
You could probably define an image for the background of the marquee (with gradients on each side) and then use mix-blend-mode in some way to fade the text. Perhaps I'm overcomplicating this. ¯\(ツ)/¯
Animate the opacity property (cleaned up the code for better readability);

Weird drop-shadow on certain backgrounds

I applied a drop-shadow filter on my clip-path, while the shadow works well on white background, it does not work at all on a darker one (example below) -
It just looks like some weird lines instead of a blurred shadow, The shadow is a bit darker then the background, making the shadow completly black makes it work at the start of the shadow but to the end it has these lines once again.
The code:
body {
margin: 0;
overflow-x: hidden;

Answer
The shadow works fine on both colors.
You can barely (or not...) see it, but it's there.
The lines are in fact the shadow.
The problem here, is the low amount of colors rendered by the screen due to the low contrast between the darkest and lightest colors (for the dark one).
Screens have a limited amount of colors. It also depends on the screen type and settings, sometimes you can easily see it (and it's ugly), sometimes you can barely notice that behavior (you just see a smooth gradient).
Example
Here is an example:
Notice I used the same shadow for both sides.
You should be able to see the lines on darker tones (the top of the left side, and all the right side). Maybe you cannot see the lines at all, again, it depends on the output device and settings.

The image in the background image is black. I want to change the color of this image. Can I add an overlay or something? Or do I have to create a new svg+xml;base64 image? Beacause I do not know how to do this.
You can't do this. You will have to create another image.

Cross-Browser / Zoom Responsive Hover Effect

I want to use hover effects such as the ones in this tutorial, but to my dismay the effect does not work responsively. There are also problems at different zoom levels and in Firefox as you will see in these screenshots. (Here is a codepen that illustrates the problem).
100% Zoom in Chrome:
90% in Chrome:
And in Firefox the effect does not work at all.
On hover in Chrome (rotating dotted line):
On hover in Firefox (no dotted line):
How can I get the effect to work responsively? Both across browsers and at different zoom levels.
Here are some code snippets that illustrate the method:
<div class="hi-icon-wrap hi-icon-effect-4 hi-icon-effect-4b">
<div class="icon-text">Product</div>
</div>
CSS:
.hi-icon-effect-4b .hi-icon:hover {
-webkit-transition: box-shadow 0.2s;
-moz-transition: box-shadow 0.2s;
transition: box-shadow 0.2s;
}
.hi-icon-effect-4b .hi-icon:hover:after {
-webkit-animation: spinAround 9s linear infinite;
-moz-animation: spinAround 9s linear infinite;
animation: spinAround 9s linear infinite;
}
#-webkit-keyframes spinAround {
from {
-webkit-transform: rotate(0deg)
}
to {
-webkit-transform: rotate(360deg);
}
}
#-moz-keyframes spinAround {
from {
-moz-transform: rotate(0deg)
}
to {
-moz-transform: rotate(360deg);
}
}
#keyframes spinAround {
from {
transform: rotate(0deg)
}
to {
transform: rotate(360deg);
}
}
Play with the codepen here. Thanks for your ideas!
Here is an attemp to solve it.
I avoid using borders, and handle everything with backgrounds: some for the stripes, another one to hide-reveal the effect, and another one to mask the inner circle.
Now it is responsive (the size of the border is the padding, that can be set as a percentage), and works ok in FF.
The backgrounds have different colors so that it is easy to see which is each one, and the rotation is delayed also to make it easier to see what is happening
But now it is failing in IE ....
Hopefully somebody can solve this

Animate div background-position (CSS)

I would like to animate the background of my div. The background position should move from left-top, to right-bottom. For some reason, nothing happens. And I have no idea why
.test {
width: 50%;
height: 250px;
background: linear-gradient(to right, rgba(255,255,255,1) 0%, rgba(255,255,255,0) 100%), linear-gradient(to bottom, green 0%, blue 100%);
background-size: 100% 100%;
animation: moving-gradient 1s infinite;
}
#keyframes moving-gradient {
0% {
background-position: left top;
}
100% {
background-position: right bottom;
}
}
JSFiddle:
http://jsfiddle.net/uLedmk5k/
You have to use fixed values for your background animation to work :
#keyframes moving-gradient {
0% {
background-position: 0,0;
}
100% {
background-position: 200px 250px, 200px 250px;
}
}
So you will have to set a fixed width to your element too :
.test {
width: 200px;
Fiddle
Edit from comments
if you set your width to viewport units it will work too :
.test {
width: 50vw;
height: 250px;
and in animation
100% {
background-position: 50vw 250px, 50vw 250px;
}
Fiddle
I'm not sure why but looking to computed tab in Firebug shows that viewport units are actually interpreted as fixed px values
Instead of moving the background image, have you tried moving the element?
translate is a very efficient and smooth (because of its anti-aliasing) way to move elements on screen, plus you can use percentages with ease.
An example Fiddle might help explain?
Although I may have completely misunderstood what you're trying to achieve.
A stupid way but works
