The following code snippet shows how I made popups with CSS and JS. Is there any chance to let it fade when opening/closing it, without changing the way I used to work, I mean just popping up the box by changing its display style?
function lightbox_open(){
window.scrollTo(100,500);
document.getElementById('light').style.display='block';
document.getElementById('fade').style.display='block';
}
function lightbox_close(){
document.getElementById('light').style.display='none';
document.getElementById('fade').style.display='none';
}
You could use either use jQuery to do the fading $().fadeIn() or use CSS3 animations if you want to stick to bare JS. In the latter case, set the opacity to 0 by default and change it to 1 via Javascript. You need to add this to your stylesheet:
selector {
opacity: 0;
-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-ms-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
transition: opacity 1s ease-in-out;
}
You can use jquery fadein() on open and fadeout() on close, but if you want to do it with pure javascript, i recommend reading this source code. they did it it wonderfully.
You can use jQuery:
.fadeIn()
function lightbox_open(){
window.scrollTo(100,500);
$('#light,#fade').fadeIn();
}
.fadeOut()
function lightbox_close(){
$('#light,#fade').fadeOut();
}

I created this site with a header that transitions using jQuery Ui and twitter bootstrap. The idea is that there are two classes .navbar-transparent and .navbar-white and I use the .switchClass() function that jQuery Ui Effects provides that transitions the change in the two classes when the scroll position of the page isn't at the top.
The problem however, the nav as it is now is, I believe the technical term is "janky". The transition isn't smooth, and when going from transparent to white the none of the font color doesn't transition at all, it just plops into black.
This shopify theme Retina / Austin does a great job of making that transition smooth with a css transition.
.header{
-webkit-transition: all 500ms ease;
-moz-transition: all 500ms ease;
-o-transition: all 500ms ease;
-ms-transition: all 500ms ease;
transition: all 500ms ease;
}
Here's my javascript code:
mindful_matter.header = function() {
if ($(".navbar-transparent").length == 0) return false;
var callback = function() {
var scrolled_val = $(document).scrollTop().valueOf();
if (scrolled_val > 0) {
$(".navbar").switchClass("navbar-transparent", "navbar-white");
} else {
$(".navbar").switchClass("navbar-white", "navbar-transparent");
}
}
callback();
$(window).scroll(callback);
}
Is there any way I can make the transition smoother? Using the setup I already have? Can I use a css transition when I have two classes that need to be swapped for one another?
.navbar{
transition: background-color 500ms ease;
}
I have a
<a onclick="document.getElementById('massage').style.display = 'block';">Button</a>
And I want to add a fadeIn to the function, but dont know how.
You have two options:
A css3 opacity animation - only suitable for HTML5 enabled browsers i.e. IE9+. Apply this by adding the css class fade to your element.
.fade {
opacity: 1;
transition: opacity .25s ease-in-out;
-moz-transition: opacity .25s ease-in-out;
-webkit-transition: opacity .25s ease-in-out;
}
2.) Use jquerys fadein function. Which supports older browsers.
http://api.jquery.com/fadeIn/
You will need to learn jQuery of course if you don't know it but this is worth doing I think.
Hope that helps
For a site I am working on I'd quite like to use a similar drop down effect as here http://shop.jack-hughes.com/ when you click info a hidden div drops down.
I can't work out if it uses only CSS3 or Javascript/CSS can anyone point me in the right direction or tell me the name of the effect; pretty simple I guess but for the life of me can't find another example.
combination of CCS3 and js
Here is what is used in the website you refer
js:
Event.observe(window, 'load', function () {
Event.observe('info', 'click', function () {
$('aside').toggleClassName('open');
});
});
Event.observe is from the prototype framework - http://prototypejs.org/doc/latest/dom/Event/observe/
The equivalent in jQuery(http://jquery.com/) for instance would be:
$(document).ready(function () {
$('.info').click(function () {
$('aside').toggleClass('open');
})
});
css:
aside.open {
height: 21.25em;
}
aside {
position: relative;
background-color: #3f4642;
width: 100%;
color: white;
letter-spacing: 0.1em;
-webkit-transition: all 0.3s ease-out;
-moz-transition: all 0.3s ease-out;
-ms-transition: all 0.3s ease-out;
-o-transition: all 0.3s ease-out;
transition: all 0.3s ease-out;
}
The HTML element is <aside>....</aside> but it's no difference if you choose div.
They have a small piece of Javascript that does this that can be easily done on any website. Basically you need a hidden div at the top of your page, and upon clicking a link you simply show the div.
The code that they used was:
Event.observe('info', 'click', function(){
$('aside').toggleClassName('open');
});
But if you take a look at jquery then you will see that manipulation of elements is quite easy to do.
One thing that they do use in addition is a CSS3 transition in their open class:
.aside {
transition: all 0.3s ease-out 0s
}
This is what is causing the smooth transition effect. So you can use either jQuery or the CSS3 transition, both give the same effect. I would say that the CSS3 transition is nicer, but then again you will be alienating certain browsers if they do not support transitions.
Probably using jQuery. Something like:
http://api.jquery.com/toggle/
In addition to what Deif discovered they're also using CSS transition
transition: all 0.3s ease-out;
and also make use of the "::selection" pseudo class for their "aside" class, see developer.mozilla.org
I have a website, and a slideshow of pictures on the main page. Before a photo is removed, I write the next photo behind it and then remove it. I wanted to know how I can add a fading effect before the photo is removed. my website is: guyzyl.org, so you can check out what im talking about. Also I dont know how to use Jquery, so please dont offer that solution. Thanks for any help. Guy Z.
.photo{
-webkit-transition: opacity .5s ease-in-out; /*Webkit*/
-moz-transition: opacity .5s ease-in-out; /*Firefox*/
-o-transition: opacity .5s ease-in-out; /*Opera*/
transition: opacity .5s ease-in-out; /*CSS3 Standard*/
opacity: 1;
}
.photo.fade{
opacity: 0;
}
document.querySelector(".photo").classList.add("fade");

I have founded this -> http://www.building58.com/examples/tabSlideOut.html
But there are some reasons that i dont want to use it:
i need prototype framework instead of jquery
i need an image to open slider (click to open) and when it opened image will change to "click to close"
Maybe someone has already the same solution of my question?
thank for you help!
CSS transitions were made for this sort of thing! For a demonstration of what you're looking for see http://jsfiddle.net/Fw7MQ/ (The 'handle' changes background colour but you could easily make that a background image instead)
The crucial parts of CSS are;
#drawer {
position: relative;
left: -200px;
/* transition is repeated for all supporting browsers */
-webkit-transition: left 0.5s ease-in-out;
-moz-transition: left 0.5s ease-in-out;
-o-transition: left 0.5s ease-in-out;
-ms-transition: left 0.5s ease-in-out;
transition: left 0.5s ease-in-out;
}
#drawer.open {
left: 0;
}
The 'drawer' has a class name added or removed as necessary using this tiny javascript snippet;
Event.observe('handle', 'click', Element.toggleClassName.curry('drawer', 'open'))
...but you could dispense with even that if the animation was done on mouseover instead - change the CSS selector from #drawer.open to #drawer:hover.
For older browsers it degrades gracefully, the animation doesn't play but the drawer still appears in the right place.
