I've created two image galleries at http://www.spanish-bookworld.com/fancybox_demo.html
The lack of "Next" button on the image when the mouse is not over it worries me. My audience is very computer illiterate and most of them will not see that there are more images in the gallery.
I reckon I have two options. One is to have a Next button permanently on the images, and the other one is to have a slideshow.
Unfortunately I can't figure out how to code either solution.
Any clues? Thanks.
As the fancybox documentation states in their button example (http://jsfiddle.net/Xh3B2/), you should try to set the CSS on fancybox navigaton to visible (and then set their position with CSS).
For your example, you should use this kind of CSS first to set the navigation always visible and then set the next/previous button position.
.fancybox-nav {
width: 60px;
}
.fancybox-nav span {
visibility: visible;
opacity: 0.5;
}
.fancybox-nav:hover span {
opacity: 1;
}
.fancybox-next {
right: -60px;
}
.fancybox-prev {
left: -60px;
}
For the slideshow option, you should set your fancybox script to "autoPlay = true. The default value is set to "false" which make the slideshow disabled.

I have a sequence of images that I want to display one at a time. All the other images are hidden with display: none. The problem is, although I'm waiting all images finish the request, when I change the image to be displayed, the image is blinking. Here is an example:
The issue happens only in Firefox. I also created a JSFiddle with the example above: https://jsfiddle.net/ofte9g5v/7/
I was able to achieve the expected behavior using opacity property but I still would like to know why the first approach doesn't work as it is the most straightforward solution and also works in all other browsers.
Edit: I forgot to mention the images blink only the first time they are loaded.
You're using JavaScript to switch the visibility in two separate calls; first you alter the CSS styles for the visible image, setting its display property to none. It looks like Firefox picks this up and paints faster than other browsers, resulting in no images showing. Next you set the display to block on one of the other images, prompting it to be painted as expected.
Generally when you want to switch between images like this you need to stack the images using CSS in order to prevent these sorts of unwanted effects. Transition Groups are a useful tool to handle transitioning state between hidden, transitioning in, visible, and transitioning out. In this case you can get by with a little CSS:
.imageContainer {
position: relative;
width: 100%;
padding-bottom: 100%;
}
.img {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
object-fit: cover;
z-index: 1;
}
Then when you want to show an image, simply set the z-index property on it to 2 or higher and set the z-index property on all other images to 1 afterward.
As an alternative, if you need the visible image to be position: relative; what I did was I set visibility:hidden; position: absolute; on the inactive images and visibility: visible; position: relative; on the active one.
The problem seems to be that Firefox doesn't decode images until they're within the viewport. So after you set the selected image to display: block; and the other images to display: none, there's a moment where no image is displayed while Firefox decodes the selected image.
The solution I found was to decode() the image prior to changing its display:
selectedImage.decode().then(() => {
for (var i = 0; i < unselectedImages.length; i++) {
unselectedImages[i].style.display = 'none';
}
selectedImage.style.display = 'block';
})
On my webpage, I have a footer which has a textarea box. When the user clicks in the textarea, I want the rest of the page to darken by 60%, kindof like they are in a modal. I am a noob when it comes to advanced css so I am unsure of the properties to apply.
I am using bootstrap 3, javascript and knockout. I know how to detect when the user is in the text area I just want to change the background so everything else is opaque.
A jsFiddle would be wonderful as well :)
We use a combination of CSS and JQuery JavaScript for that. You'd basically use some Overlay method first to overlay the whole page (e.g. See Technique #1 from the Link).
With the help of JavaScript, We attach to events of the forms to:
Show the Overlay
Make the required form elements, e.g. the first Div inside the form, appear above the Overlay ("z-index" CSS attribute)
CSS:
Overlay has Z-Index 10, so give the relevant element the Z-Index 11 to appear on top:
form > div { z-index: 11; }
this JQuery JavaScript can look like this:
$(document).on("focus", "textarea", function() {
$(".overlay").show();
});
Beware, this is not only a "background" topic, if you want to prevent users to do any interaction with the page, you need an overlay which actually blocks clicks. Also, in our case, we also had to prevent any links to be triggered which are below the overlay. Users were still able to go through the links using the TAB key on they keyboard to navigate to a button and click it using the Space key, so we also added JavaScript code to prevent that when in editing mode.
EDIT: a very basic Fiddle
Here is how I would do this - When the user clicks in the text area, set a class on body, and style the class.
with jQuery (you can use vanilla js too)
$('.my-textarea').on('focus', function() {
$('body').addClass('dark');
});
$('.my-textarea').on('blur', function() {
$('body').removeClass('dark');
});
body.dark {
background-color: #333;
opacity: 0.6;
}
A good solution is to make a modal appear behind the input and not just making the background darker, this can be accomplished with css alone
...
<style>
textarea:focus{
z-index: 901;
position: relative;
}
textarea ~ .textarea-modal{
position: fixed;
background-color: transparent;
margin: auto;
left: 0;
right: 0;
top: 0;
bottom: 0;
width: 100%;
height: 100%;
z-index: 900;
pointer-events: none;
transition: background-color .5s ease;
}
textarea:focus ~ .textarea-modal{
pointer-events: auto;
background-color: rgba(0,0,0,0.3);
}
</style>
...
<div>
<textarea></textarea>
<div class="textarea-modal"></div>
</div>
...
feel free to change the selectors to target specific elements, however at the moment when you focus on the textarea a modal would appear below it with other elements behind.
I have the script from previous stack overflow question on how to pick an image from an array at random.
Script to display an image selected at random from an array on page load
I want to take his idea a bit further, and display this image fullscreen on page load. I am working on a website, and had the idea to use an image as a greeting page. Where, when the page loads, you are greeted with a fullscreen HD image. When clicked, this image would disappear and show the full site. I wasn't exactly sure how to accomplish this though. Any ideas?
Edit: I'm not looking for direct implementation. Just general thoughts or jsFiddles on how to accomplish this task.
For showing the image on the page load you can use $( document ).ready() function. on click() of the image you could show the website.
Try using CSS like,
First option,
img {
position: fixed;
top: 0;
left: 0;
/* Preserve aspet ratio */
min-width: 100%;
min-height: 100%;
}
Second option,
img {
/* Set rules to fill background */
min-height: 100%;
min-width: 1024px;
/* Set up proportionate scaling */
width: 100%;
height: auto;
/* Set up positioning */
position: fixed;
top: 0;
left: 0;
}
To understand the above options read Perfect Full Page Background Image
I recommend you to use a complete full page background image slider for your problem. If it is available then use it without wasting your time.
I found a full page slider on http://www.freshdesignweb.com/fullscreen-jquery-slider.html in which the first one background slider is best suitable to you.
Also you can go to https://www.google.co.in/?q=full+background+image+slider to get more image sliders
I'm beginner and trying to display details of a card/tile from the sliding bottom of the page over click action. I already found one of the template with my requirements and trying to customize. I found few code samples on how can I do sliding effect from the bottom. I was able to findout solution but it works with hover action where as I am trying to do is as below.
Scenario:
As shown in the mockup screenshot >> Cards will be displayed in the home screen >> users clicks on one of the Card >> background should be transparent 50% and movie details should get displayed in sliding button panel >> PLAY NOW should be active
Like the left menu loading in the given template below - playdo template
one of the similar example I found is this but as I mentioned this is hover feature - Sliding bottom panel through HTML, CSS and JS
An other from the top sliding - http://hoveralls.design-way.ro/
Template in the screenshot that i am using is - https://github.com/tomclaus/playdo
Hi and welcome to the front-end world.
What you need to do is to create two different css classes that contain the things you want to change (in this case the top and the transparency). One for when your card/tile is "minimized" and one for when is "maximized".
.minimized{
background-color: rgba(255,255,255, 0.5);
top: 90%;
}
.maximized{
background-color: rgba(255,255,255, 1);
top: 75%;
}
and then apply a click event to your card/title using jQuery or Javascript and swap those classes to give the proper behavior.
$("#card").click(function(){
if($(this).hasClass('minimized')){
$(this).removeClass('minimized');
$(this).addClass('maximized');
}
else{
$(this).removeClass('maximized');
$(this).addClass('minimized');
}
});
Make sure that the CSS for your card/tile includes this:
-webkit-transition: all ease 1s;
That line will give a smooth transition when you swap the minimized and maximized classes.
Please check this jsfiddle to see the code in action.
ps. Since I'm using the "-webkit-" prefix for the transition this example only will work with webkit browsers (safari and chrome)
Ok I finally understood what you want to do with the mockup.
Well the idea is the same, and I'm sure it can be implemented in many other ways but I hope this one helps you to understand what is going on.
Pretty much you need two states (classes) for the actions you want to achieve.
A Minimized and Maximized for the div that holds the movie details.
#details{
z-index: 4;
position: absolute;
-webkit-transition: all ease 1s;
background-color: #2980b9;
color: white;
padding: 30px;
width: 100%;
height: 300px;
}
.minimized{
top: 100%;
}
.maximized{
top: 40%;
}
And other two for the "gray courtain" that sits on top of the cards when the details are show.
#courtain{
position:absolute;
background-color: rgba(100,100,100, 0.5);
width: 100%;
height: 100%;
}
.active{
z-index: 2;
}
.deactive{
z-index: -1;
}
All these must be controlled or toggled using Javascript with a click event for the Card.
function hideAndShow(){
var details = $('#details');
var courtain = $('#courtain');
if(details.hasClass('minimized')){
courtain.removeClass('deactive');
courtain.addClass('active');
details.removeClass('minimized');
details.addClass('maximized');
}
else{
courtain.removeClass('active');
courtain.addClass('deactive');
details.removeClass('maximized');
details.addClass('minimized');
}
}
It is important to check the "z-index" values on the states to place them correctly above the other, the one with the highest z-index value is the one that remains on top.
I've updated the JSFiddle, check it out and hopefully all this makes sence.
I am working on this site http://www.group---me.my/national/
Please remove --- in the url.
For certain deals, there is options, and when you click on the BuyNow button, a popup comes up. I would like to dim (darken) the background, while the popup is shown.
To do this, on my local test site, I added the following div class:
.overlay{
display: none;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 333%;
background-color: black;
z-index: 20;
opacity: 0.8;
filter: alpha(opacity=80);
}
Then on the Buy Now button, I added
onclick="javascript:document.getElementById('fade').style.display='block';"
I also have this in the site
<div id="fade" class="overlay"></div>
But the problem is, the overlay always hides all the layers, including the popup, regardless how high I set the popup div's z-index.
Any help is much appreciated. Thanks.
Which browser? Which version. I am getting it right here. It should hide right?
And it is prominent. What is that you wanna do here?
If you doesn't specify some parent element to be relative positioned, your overlay div will be positioned relative to body so it can be above all other content.
