I’m trying to use Compass animation mixin with multiple animations. Is this possible?
I’ve tried #include animation(an-1 5s infinite, an-2 10s infinite), but I’m getting an error: Mixin animation takes 1 argument but 2 were passed.
Your compass syntax is correct and works in the current version of compass. Maybe this wasn’t the case in a previous version.
Demo on Codepen
Though you can always combine both animations into one (if both animations should use the exact same options, e.g. easing):
#include animation(an-3 5s ease-in infinite);
#include keyframes(an-3) {
from {
transform: scaleY(0);
opacity: 0;
}
to {
transform: scaleY(1);
opacity: 1;
}
}

So I've got my _grid-settings.css.scss defined as per the docs and in it, among some of the other default overrides is $max-width: 1200px;.
Part of the contents of my override:
$visual-grid: true;
$visual-grid-color: green;
$visual-grid-index: front;
$visual-grid-opacity: 0.2;
$column: 90px;
$gutter: 30px;
$grid-columns: 8;
$max-width: 1200px;
I know this is working because I'm using the visual grid as well and when I change $max-width to 100% I see that change occur.
The problem I'm having is that my #include outer-container on my body is not being respectful of this value, contrary to the docs, it seems not to notice it.
body {
#include outer-container;
}
When I change this to #include outer-container(1200px); the content then falls into place alongside the rest of the grid.
The problem was that I was also using Bitters and did not know that it has its own grid settings as well. I had to make sure that I uncomment #import "grid-settings"; from base/_base.css.scss as per the docs' instructions.
I'm working with SASS/Compass sprite libraray and I'm trying to configure my sprite to work with 3 icon sizes: 1x, 1.5x and 2x (retina)
this is the import of the folders:
#import "icons10/*.png";
#include all-icons10-sprites;
#import "icons15/*.png";
#include all-icons15-sprites;
#import "icons20/*.png";
#include all-icons20-sprites;
this is a mixin I am writing to manage these sprites:
#mixin my-icon($name) {
#extend .icons10-#{$name};
#media (-webkit-min-device-pixel-ratio: 1.5) {
#extend .icons15-#{$name};
background-position: 100% 100%;
}
#media (-webkit-min-device-pixel-ratio: 2) {
#extend .icons20-#{$name};
}
$icon-width: icons10-sprite-width($name);
$icon-height: icons10-sprite-height($name);
width: $icon-width;
height: $icon-height;
}
I'm completely clueless on how to manage backround-size and background-position in order to make the 1.5x and the 2x library to work. My questions are:
is there a retina solution for this specific SASS library?
I can manage my manual solution if I can fetch the sprite's dimensions themselves, but I don't understand how can I fetch the dimensions of the whole sprite
There is no such build in solution in SASS so far. But if you are willing to switch to sprite maps, there is a way to get the sprite maps size:
background-size: image-width(sprite-path( [your sprit emap] )) image-height(sprite-path( [your sprite map] ))
There is a great piece of code from Gaya Kessler on retina sprites for compass you should check out: Retina Sprites for Compass.
Adding your third icon size shouldn't be a problem.
try this:
https://gist.github.com/alanhogan/2878758
if sprite-url not work, you can try sprite-file
Is there a standard way to scale all the sprites created by compass? That is, have a image which is double the resolution I need and I wish to have all sprites from that image be have the size. Currently I can do this by iterating over the loaded sprites and setting the background-size and modifying the background-position.
For clarity, by example, if I were using normal sized sprites I'd just do this:
#import "settings/*.png";
#include all-settings-sprites;
But to get the double sized sprites I have to do this:
#import "icons/*.png";
#include retina-sprites($icons-sprites); // retina sprites
#mixin retina-sprites($map) {
$base-class: sprite-map-name($map);
.#{$base-class}-all-retina-sprites {
background-image: sprite-url($map);
#include background-size(ceil(image-width(sprite-path($map)) / 2) auto);
}
#each $sprite in sprite-names($map) {
.#{$base-class}-#{$sprite} {
#extend .#{$base-class}-all-retina-sprites;
$position: sprite-position($map, $sprite);
background-position: nth($position, 1) nth($position, 2) / 2;
}
}
}
I'm hoping there's an easier or standard way to do this. The problem gets worse as I try to include individual sprites in the CSS file elsewhere since I can't use any of the standard definitions.
Is it possible to override the default gutter value for a container with base values e.g. like that:
$total-columns: 12;
$column-width: 60px;
$gutter-width: 20px;
$grid-padding: 10px;
So that you would be able to minimize the gutter from 20px to e.g. only 5px, or any other desired value, on demand.
.example{
#include squish(1,1);
li{
#include span-columns(2,10);
#include nth-omega(5n);
}
}
Is it possible via a mixin, would i have to place another container/layout or should i stick with plain CSS to solve that task? Thanks
Update:
To be more specific, i don't look for an exact sizing of the gutter (as far as i read so far, due to rounding, it would be difficult anyway), i just want to minimize the gutter and enlarge the column width indirectly.
https://dl.dropbox.com/u/8578/Boxes.png
At the moment i have squished 3 columns before and after the contained 7 columns and their gutters. So far the columns and its images are too small in width. Therefor i wanted to size down the gutter width and enlarge the column width indirectly.
The Susy settings look that way:
$total-columns: 24;
$column-width: 3%;
$gutter-width: 1%;
$grid-padding: 0;
A container width i haven't set so far since the container is inside a wrapper for the whole page.
.wrapper {
#include container;
overflow-x: hidden;
width:100%;
max-width: 100%;
}
The specific selector for the image matrix shown in the screenshot is the following:
.projects {
#include squish(3,3);
li {
#include span-columns(2,14);
#include nth-omega(7n);
}
}
You need any more details? So would you still recommend to use the with-grid-settings mixin to solve that problem? And is the set-container-width mixin really necessary? Thought if i set up things relative no absolute values should be necessary? Thanks Ralf
Update 2:
Ufff i tried the suggested little secret's approach mentioned in the comments beneath. But so far i was unable get a clean display, more like a messy chaotic "patchwork"... ;) Kind of confusing over all. Basically the articles author recommended 2 steps. First he added -100% margin-right for the content containing element and in the next step pushed the objects back into their places. My last setup in a long line of tries looks like that right now but still no solution in sight.
.example{
#include squish(3,3);
#include with-grid-settings($gutter: 0.1%){
margin-right: -100%;
li{
#include span-columns(6,18);
#include nth-omega(3n);
#include pre(9);
}
}
}
The margin-right i've placed within the with-grid-settings mixin in the containing element for "li" like suggested. But the question is where to place the pre mixin and especially which numbers it should contain (has the number to take the squish number in consideration too)? Is it the same value for all li or is a for loop necessary to push the images to individually to their horizontal positions ? And is the mixin order within the li element correct? Does it matter where it is placed? At the end or inbetween span-columns and nth-omega? Over all i am still confused. Grids, image matrices and Susy still keep my brain spinning. :/
Update 3:
Thanks! I finally got it working. In the end i would have two questions about my solution:
.test{
#include with-grid-settings($gutter: 0.1%){
li{
margin-right: -100%;
float:left;
#include span-columns(6,18);
#include nth-omega(3n);
$count:0;
#for $i from 1 through 9 {
&:nth-child(#{$i}) {
$count: $count + 1;
#include push($count);
#if $count == 2{ $count: 0;}
}
}
}
}
}
Would there be a more elegant way for the layout of the for loop? And second why is it possible that this version as well as a version when i comment out the $count: $count + 1; statement lead to the same visual result? Actually commented out there isn't a second and third count up for the push variable. Any idea why that works anyway without the $count: $count + 1;? Thanks!
Update 4:
I played around a little bit more and as it turns out the following version works like a charm. It seems the $count variable isn't necessary at all, as well as the incremental growing of the value contained within the push/pre mixin. A simple 0 did the trick.Thanks again for the help!!!
.test{
#include with-grid-settings($gutter: 0.5%){
li{
margin-right: -100%;
#include span-columns(6,18);
#include nth-omega(3n);
#for $i from 1 through 9
{
&:nth-child(#{$i})
{
#include push(0);
}
}
}
}
}
Update 5
I already mentioned in my last comment beneath that the example shown in update 4 hasn't worked as good as it supposed to work at the first look. I tried now to completely rebuild the suggestion from the Palantir article. Underneath is the scss parts for the 7x4 as well as the 3x3 matrix shown in the video: https://dl.dropbox.com/u/8578/matrix.mov
.7x3{
#include with-grid-settings($gutter: 0.25%){
li{
margin-right: -100%;
#include trailer(1);
#include span-columns(2,14);
#include nth-omega(7n);
$y: 0;
#for $x from 1 through 28
{
&:nth-child(#{$x}){
margin-left: ($y * columns(2,14)) + ($y * gutter(14));
$y: $y + 1;
#if $y > 6{
$y: 0;
}
}
}
}
}
}
.3x3{
#include with-grid-settings($gutter: 1%){
li{
margin-right: -100%;
#include trailer(1);
#include span-columns(6,18);
#include nth-omega(3n);
$j: 0;
#for $i from 1 through 9
{
&:nth-child(#{$i}){
margin-left: ($j * columns(6,18)) + ($j * gutter(18));
$j: $j + 1;
#if $j > 2{
$j: 0;
}
}
}
}
}
}
At the first look the matrices look broken but if you take a closer look at the inspector within the video, it appears that each element is pushed to its correct horizontal position in both matrices. Only problem is that each li is contained in separate lines. This is the closest version i was able to get. :/ Right now i am out of ideas how to put those pieces together to get to a proper matrix. I tried more or less ever possibility with float as well as display properties. But no luck. Anyone has a hint perhaps?
You can use with-grid-settings() (reference docs) to wrap your code:
Since you don't want to change the actual container width, we can leave that alone. It's up to you if you want the .projects padding (from squish()) to be influenced, but I'm going to assume you don't. Here it is, just changing the $gutter-width for the lis:
#include with-grid-settings($gutter: .5%) {
li {
#include span-columns(2,14);
#include nth-omega(7n);
}
}
That's it. If you do want anything else to use the adjusted settings, simply move them inside the mixin.
I am trying to replicate an Apple style activity indicator (sundial loading icon) by using a PNG and CSS3 animation. I have the image rotating and doing it continuously, but there seems to be a delay after the animation has finished before it does the next rotation.
#-webkit-keyframes rotate {
from {
-webkit-transform: rotate(0deg);
}
to {
-webkit-transform: rotate(360deg);
}
}
#loading img
{
-webkit-animation-name: rotate;
-webkit-animation-duration: 0.5s;
-webkit-animation-iteration-count: infinite;
-webkit-transition-timing-function: linear;
}
I have tried changing the animation duration but it makes no difference, if you slow it right down say 5s its just more apparent that after the first rotation there is a pause before it rotates again. It's this pause I want to get rid of.
Any help is much appreciated, thanks.
Your issue here is that you've supplied a -webkit-TRANSITION-timing-function when you want a -webkit-ANIMATION-timing-function. Your values of 0 to 360 will work properly.
You also might notice a little lag because 0deg and 360deg are the same spot, so it is going from spot 1 in a circle back to spot 1. It is really insignificant, but to fix it, all you have to do is change 360deg to 359deg
my jsfiddle illustrates your animation:
#myImg {
-webkit-animation: rotation 2s infinite linear;
}
#-webkit-keyframes rotation {
from {-webkit-transform: rotate(0deg);}
to {-webkit-transform: rotate(359deg);}
}
Also what might be more resemblant of the apple loading icon would be an animation that transitions the opacity/color of the stripes of gray instead of rotating the icon.
You could use animation like this:
-webkit-animation: spin 1s infinite linear;
#-webkit-keyframes spin {
0% {-webkit-transform: rotate(0deg)}
100% {-webkit-transform: rotate(360deg)}
}
If you're only looking for a webkit version this is nifty: http://s3.amazonaws.com/37assets/svn/463-single_spinner.html from http://37signals.com/svn/posts/2577-loading-spinner-animation-using-css-and-webkit
Your code seems correct. I would presume it is something to do with the fact you are using a .png and the way the browser redraws the object upon rotation is inefficient, causing the hang (what browser are you testing under?)
If possible replace the .png with something native.
see; http://kilianvalkhof.com/2010/css-xhtml/css3-loading-spinners-without-images/
Chrome gives me no pauses using this method.
I made a small library that lets you easily use a throbber without images.
It uses CSS3 but falls back onto JavaScript if the browser doesn't support it.
// First argument is a reference to a container element in which you
// wish to add a throbber to.
// Second argument is the duration in which you want the throbber to
// complete one full circle.
var throbber = throbbage(document.getElementById("container"), 1000);
// Start the throbber.
throbber.play();
// Pause the throbber.
throbber.pause();
Example.
