SCSS animation doesn't work - ruby-on-rails

It is my sccs code:
#logo{
animation: zoomIn, 4s;
}
#mixin keyframes($name) {
#keyframes #{$name} {
#content;
}
}
// use of keyframes mixin
#include keyframes(zoomIn) {
0% {
opacity: 0;
transform: scale3d(.3, .3, .3);
}
50% {
opacity: 1;
}
}
And this is my HTML code:
<!DOCTYPE html>
<html>
<head>
<title>Dako</title>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
</head>
<body class='<%= controller.controller_name %>'>
<div id="top"><%= image_tag('dako.png', id:'logo') %></div>
...
Why it doesn't animate? I was trying add the prefix webkit- but it didn't help me.

There's a few issues with your scss code;
You need to add the -webkit prefix in front of both keyframes and animation
Make sure you declare the keyframes before using them (at the moment #logo is looking for animation: zoomIn but it doesn't exist yet)
You shouldn't have commas in your animation statement
Your final code should look something like this
//Keyframe Mixin
#mixin keyframes($name) {
#keyframes #{$name} {
#content;
}
#-webkit-keyframes #{$name} {
#content;
}
}
// Create Keyframes
#include keyframes(zoomIn) {
0% {
opacity: 0;
transform: scale3d(.3, .3, .3);
}
50% {
opacity: 1;
}
}
//Use Animation
#logo{
animation: zoomIn 3s;
-webkit-animation: zoomIn 3s;
}

Modify original Position on jQuery ui Drag & Drop

I have an application with multiple stack of card, I would like to have a drag&drop ability between these stacks.
These stacks have a different layout in term of offset relative to the parent element.
I simplified to the max in this fiddle
https://jsfiddle.net/dtghbo7f/
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

.card, .box {
width: 71px;
height: 96px;
position: absolute;
}
#box1 {
top:31px;
left:25px;
}
#box2 {
top:31px;
left:255px;
}
.card {
background-image: url[...]
}
.box {
background-position: -1px -1px;
background-image: url[...]
}
</style>
<script src="jquery.min.js"></script>
<script src="jquery-ui.js"></script>
<script>
$("body").ready(function() {
$('<div>').attr('id','card0').addClass('card').appendTo($('#box1'));
for(let i=1;i<7;i++){
$('<div>').attr('id','card'+i).addClass('card').appendTo($('#box1 div.card:not(:has(*))')).css('top',5).css('left',5);
}
$('<div>').attr('id','card7').addClass('card').appendTo($('#box2'));
for(let i=1;i<7;i++){
$('<div>').attr('id','card'+(i+7)).addClass('card').appendTo($('#box2 div.card:not(:has(*))')).css('top',15);
}
$(".card").draggable({
revert: true,//'invalid',
revertDuration: 500,
start: function(event, ui) {
$(this).parents(".box").css('z-index',2);
},
drag: function(event, ui) {
},
stop: function(event, ui) {
$(".box").css('z-index',1);
if($(this).parents('.box').attr('id') == 'box1') {
$(this).css('top',5).css('left',5);
} else {
$(this).css('top',15).css('left',0);
}
},
});
$(".box, .card").droppable({
activate: function( event, ui ) {return false;},
drop: function( event, ui ) {
let source_offset = ui.draggable.parent().offset();
let destination_offset = $(this).offset();
$(this)
.append(ui.draggable);
ui.draggable
.css('top', parseInt(ui.draggable.css('top')) + parseInt(source_offset.top) - parseInt(destination_offset.top))
.css('left', parseInt(ui.draggable.css('left')) + parseInt(source_offset.left) - parseInt(destination_offset.left));
console.log(ui.draggable.css('top'), ui.draggable.css('left'));
$('.card, .box').droppable('enable');
$('.card:has(*), .box:has(*)').droppable('disable');
},
});
$('.card, .box').droppable('enable');
$('.card:has(*), .box:has(*)').droppable('disable');
});
</script>
</head>
<body>
<div id='box1' class='box'>
</div>
<div id='box2' class='box'>
</div>
</body>
</html>
As you can see, when you drop a card on the other stack, the revert options move the card to the original position relative to the parent. As this offset change on different stack, I would like to be able to modify this originalPosition when the droppable stack is determined. Can you help me ?

Rails 6: How to add jquery-ui through webpacker?

I'm currently trying to implement a datepicker into my application, the problem is that there is no documentation on how to add the jquery-ui-rails gem through webpacker.
Probably there is another way to add gems or another gem that would fit my needs?
You no longer need to add javascript libraries as gems (which are managed by the bundler). Instead, you add them with yarn and they are managed by webpack (which is enabled by adding the webpacker gem to the Gemfile).
The following steps worked for me to get jquery-ui working in Rails 6:
On the terminal, inside your application type:
yarn add jquery-ui-dist
Your config/webpack/environment.js needs to look as follows:
const { environment } = require('#rails/webpacker')
const webpack = require('webpack')
environment.plugins.prepend('Provide',
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery'
})
);
const aliasConfig = {
'jquery': 'jquery-ui-dist/external/jquery/jquery.js',
'jquery-ui': 'jquery-ui-dist/jquery-ui.js'
};
environment.config.set('resolve.alias', aliasConfig);
module.exports = environment
Restart your rails server
In the application.html.erb, include the jquery-ui theme:
<!DOCTYPE html>
<html>
<head>
<title>Jquery UI Test</title>
<%= csrf_meta_tags %>
<%= csp_meta_tag %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= stylesheet_link_tag '//ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/themes/le-frog/jquery-ui.min.css' %>
<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>
</head>
<body>
<%= yield %>
</body>
</html>
Now, in your app/javascript/packs/application.js, you can use jquery-ui:
NOTE: If you would like to use jQuery inside your views folder, make it available globally
require("#rails/ujs").start()
require("turbolinks").start()
require("#rails/activestorage").start()
require("channels")
// THIS IS MAKING jQuery AVAILABLE EVEN INSIDE Views FOLDER
global.$ = require("jquery")
require("jquery") // Don't really need to require this...
require("jquery-ui")
$(function(){
// Plain jquery
$('#fadeMe').fadeOut(5000);
// jquery-ui
const availableCities = ['Baltimore', 'New York'];
$('#cityField').autocomplete( { source: availableCities } );
$('#calendarField').datepicker( { dateFormat: 'yy-mm-dd' } );
})
This will work for a page that looks as follows:
<div id='fadeMe'>I will fade</div>
City: <input type='text' id='cityField' />
Calendar: <input type='text' id='calendarField' />
None of these answers quite worked for me. Here's how I ended up getting it implemented:
yarn add jquery
then
yarn add jquery-ui-dist
in your app/javascript/packs/application.js file:
// jquery
import $ from 'jquery';
global.$ = $
global.jQuery = $
require('jquery-ui');
// jquery-ui theme
require.context('file-loader?name=[path][name].[ext]&context=node_modules/jquery-ui-dist!jquery-ui-dist', true, /jquery-ui\.css/ );
require.context('file-loader?name=[path][name].[ext]&context=node_modules/jquery-ui-dist!jquery-ui-dist', true, /jquery-ui\.theme\.css/ );
and in config/webpack/environment.js:
const { environment } = require('#rails/webpacker');
const webpack = require('webpack');
// resolve-url-loader must be used before sass-loader
environment.loaders.get('sass').use.splice(-1, 0, {
loader: 'resolve-url-loader',
options: {
attempts: 1
}
});
// Add an additional plugin of your choosing : ProvidePlugin
environment.plugins.prepend('Provide', new webpack.ProvidePlugin({
$: 'jquery',
JQuery: 'jquery',
jquery: 'jquery',
'window.Tether': "tether",
Popper: ['popper.js', 'default'], // for Bootstrap 4
})
)
const aliasConfig = {
'jquery': 'jquery/src/jquery',
'jquery-ui': 'jquery-ui-dist/jquery-ui.js'
};
environment.config.set('resolve.alias', aliasConfig);
//
module.exports = environment;
A restart to my server got it working fine for me. Here is a link with details on webpacker that I used to get this to work:
https://gist.github.com/maxivak/2612fa987b9f9ed7cb53a88fcba247b3#jquery-jquery-ui
$ yarn add webpack-jquery-ui
and in application.js
require('webpack-jquery-ui');
require('webpack-jquery-ui/css');
did the job for me.
(I had setup jquery before which might need some additional config)
Weblink: https://www.npmjs.com/package/webpack-jquery-ui
(This is the same process as in Tushar Patil's answer yet with another package).
Kalman's answer worked for me, although not from the very beginning (I'm writing it in a separate answer as I don't have enough reputation to comment on the original answer yet :) )
So, beware that when you put require("jquery-ui") in app/javascript/packs/application.js, the functions provided by jquery-ui will not be available in your scripts loaded to individual views with javascript_pack_tag
The reason for that is that these individual scripts will load before application.js loads.
To make it work, I had to put require("jquery-ui") in one of these individual scripts that depended on jquery-ui
BTW, it works in Kalman's example, as he wrote his script directly in application.js, after requiring "jquery-ui"
Kalman's answer puts jQuery within the scope of the scripts in the app/javascript directory but not with any in-line javascript that you may have on your webpages.
If you want to access jQuery from the scope of the webpage, you could can put jQuery under the public directory then modify app/views/layouts/application.html.erb to link to it like this:
<!DOCTYPE html>
<html>
<head>
<title>JqueryTest</title>
<%= csrf_meta_tags %>
<%= csp_meta_tag %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>
<script src="/jquery-3.4.1.js"></script>
<%= stylesheet_link_tag "/jquery-ui-1.12.1.custom/jquery-ui.min.css" %>
<script src="/jquery-ui-1.12.1.custom/jquery-ui.min.js"></script>
</head>
<body>
<%= yield %>
</body>
</html>
Above steps works fine, removed extra steps
The following steps worked for me to get jquery-ui working in Rails 6:
1) On the terminal, inside your application type:yarn add jquery-ui-dist
2) in app/javascript/packs/application.jsrequire("jquery-ui-dist/jquery-ui");
3) In the application.html.erb, include the jquery-ui theme
<%= stylesheet_link_tag '//ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/themes/le-frog/jquery-ui.min.css' %>
4) restart the rails server and webpack dev server.
For me a hybrid of several articles, and things worked and looked the most elegant
CLI:
yarn add jquery jquery-ui-dist
app/javascript/packs/application.js:
// ... SNIP ...
require("jquery")
require("jquery-ui")
config/webpack/environment.js:
const { environment } = require('#rails/webpacker')
const webpack = require('webpack')
environment.plugins.prepend('Provide',
new webpack.ProvidePlugin({
$: 'jquery/src/jquery',
jQuery: 'jquery/src/jquery'
})
)
const aliasConfig = {
'jquery': 'jquery/src/jquery',
'jquery-ui': 'jquery-ui-dist/jquery-ui.js'
};
environment.config.set('resolve.alias', aliasConfig);
module.exports = environment
app/views/layouts/application.html.erb
<%= stylesheet_link_tag '//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css' %>
Run on the terminal (CLI)
yarn add jquery jquery-ui-dist
Add to the config/webpack/environment.js
...
const webpack = require("webpack")
environment.plugins.append("Provide",
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery'
})
)
const aliasConfig = {
'jquery': 'jquery/src/jquery',
'jquery-ui': 'jquery-ui-dist/jquery-ui.js'
};
environment.config.set('resolve.alias', aliasConfig);
...
app/javascript/packs/application.js:
require("jquery-ui")
For the theme add code to any scss file. Do change according to your nee.

Cannot pause CSS animation in mobile Safari

I try to pause a CSS animation with JavaScript.
This works in all tested browsers but not in Safari on iOS, where the animation continues until the end.
How to fix or workaround this bug?
(function () {
function setAnimationPlayState (state) {
document.getElementById ('debug').innerHTML += state + '/';
document.getElementById ('animation').style.animationPlayState = state;
document.getElementById ('animation').style.webkitAnimationPlayState = state;
}
window.addEventListener ('load', function () {
setAnimationPlayState ('running');
setTimeout (function () {
setAnimationPlayState ('paused');
}, 1000);
});
} ());
#animation {
animation: test linear 4s;
animation-fill-mode: both;
}
#keyframes test {
to {
/* 3D never pause */
transform: rotateY(90deg);
/* 2D may pause or not */
/* transform: translateX(100vw); */
}
}
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<div id="debug" style="color: red;">/</div>
<div id="animation">Hello<br>this text<br>should not<br>disappear<br>completely</div>
</body>
</html>
My animation is 3D so I also tested with a 2D animation just in case, and the behavior is even weirder. Sometimes it works, then I reload the page and it doesn't work. This thing is driving me crazy, your help is most welcome.

This leads to a slide title under a significant margin and parts of the slide hidden.
reveal.js has a "height" option that can be set when you call Reveal.initialize.
With pandoc, provided you have a recent templates/default.revealjs, you can set the "height" variable:

SCSS Not Rendering - Agile Web Development With Rails 4 (Book)

I've copied the raw text files from the book for the tutorial that I'm working on, and the css is not being applied and I can't figure out why. The HTML content displays correctly though. Perhaps you will need more information from me that I'm unaware of at the moment, but I'm glad to bring it to the table if need be.

Error
You fixed it - congrats!!
Something you may wish to consider is using SASS instead of SCSS. You only need to change the extension of your file to .css.sass - allowing you to get rid of a lot of superfluous brackets in SCSS:
#app/assets/stylesheets/application.css.sass
.products
table
border:
collapse: collapse
& tr td
padding: 5px
vertical:
align: top
--
Stylesheets
Instead of inline-styling your body tag, why not create applicable stylesheets for each controller, and styling the body from these?
Like this:
#app/views/layouts/application.html.erb
<%= stylesheet_link_tag "application", controller_name, media: "all","data-turbolinks-track" => true %>
This will allow you to keep default styling in your application.css.scss, and use things like a background image in your various [controller].css.scss files:
app
| - assets
| - stylesheets
- application.css.scss
- controller1.css.scss
- controller2.css.scss
You'll then need to remember to add these assets to your pre-compilation procedure:
Rails.application.config.assets.precompile += ['controller1.css', 'controller2.css']
This will make your styling a LOT DRYer & more versatile
