How to use transparency with supersized jquery plugin - jquery-plugins

I just downloaded and tried supersized jquery plugin. It's really cool but I can't seem to set transparency on the background image. I read the documentation on their site and couldn't find a way to set it.
Is there anyway I can achieve it?

I would find the supersized.css file and edit #supersized for opacity
#supersized {
display: block;
position: fixed;
left: 0;
top: 0;
overflow: hidden;
z-index: -999;
height: 100%;
width: 100%;
opacity:0.6;
filter:alpha(opacity=60); /* For IE8 and earlier */
}
If you wanted to make specific opacity for specific slides you could make more specific selectors and alter those to your liking.

Background-size pixels polyfil for IE8?

I need to make CSS3's background-size properly work in IE8. There are a lot of javascript libraries out there but they extend the options "cover" and "contain" rather than a px value. As I'm using an image sprite I need to set the background size in pixels.
Here is a demo of my code. The sprite image is 600px 400px but ive set the background size to be 300px x 200px so that is looks crisp on high density displays.
<a class="one">Link one</a>
<a class="two">Link two</a>
a {
overflow: hidden;
text-indent: -9999px;
display: block;
width: 58px;
height: 58px;
background: url("https://cdn.tutsplus.com/webdesign/uploads/legacy/tuts/373_sprites/angry_birds.png");
background-size: 300px 200px;
} a.one {
background-position: 0 0;
}
a.two {
background-position: 0 -56px;
}

Can I extend support to IE8 without having to create and maintain a 2nd image sprite?
Depending on the specific case, which you don't really explain in much detail, a workaround with pseudo elements may work?
Just add a pseudo element of the specified size and have it have the sprite as background?
With the right combination of position absolute/relative and z-index this could work.
If you provide more information of what exactly you are trying to achieve I will be able to provide better help.
Edit:
Okay, so I got a solution now. Kind of as expected: looks quite dirty.
But that's what you get when you want to do fancy stuff in IE8 :-P
a {
overflow: hidden;
text-indent: -9999px;
display: block;
width: 58px;
height: 58px;
position: relative;
}
a:before {
content: "";
background: url(https://cdn.tutsplus.com/webdesign/uploads/legacy/tuts/373_sprites/angry_birds.png);
zoom: .5;
text-indent: 0;
overflow: hidden;
width: 600px;
height: 400px;
position: absolute;
left: 0;
top: 0;
}
a.one:before {
background-position: 0 0;
}
a.two:before {
background-position: 0 -112px;
}
The downside of this is, that you would have to calculate the zoom factor instead of just writing down the dimensions you want to have. Also background-position would then be in relation to the full-size background.
Is anything unclear with what I am doing in above code?
The only thing you can do is to :
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='image.gif',
sizingMethod='scale');
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='image.gif',
sizingMethod='scale')";
But this can cause issues if you use sprite image.
According to caniuse.com, this polyfill may help.
Hope this helps...

How to center images for small mobile that were floated on desktop

I often float images either left or right around text on desktop but I want them centered for small mobile devices and the paragraph to drop below the image using Responsive design. I've got the paragraph dropping below the image using an online mobile viewing device but not when I try to view it via my computer. The image won't center online or on my computer.
Here is what I have found after many hours of research:
I have this set up for all images:
img{
border:0;
max-width:100%;
height:auto;
}
I have this set up for all paragraphs: it pushes the paragraph down below a floated image when the width of the paragraph is less than 10em (about 200 px).
p:before{
content: "";
width: 10em;
display: block;
overflow: hidden;
}
I have applied the following for images to media queries less than 320 and max of 480:
img{
max-width:100%;
display:block!important;
margin:0 auto !important;
float:none !important;
}
(i had to add !important to some of them or they wouldn't take but it's still not accepting margin: 0 auto; )
Can anyone see what I'm doing wrong?
Here you have a working update of what you need: http://jsfiddle.net/ancpjmet/3/
I changed min-devide-width to min-width and max-devide-width to max-width to be able to see the changes on my desktop browser in Google Chrome.
You have to set the div wrapping the img to float: none;, not the img:
#media only screen and (min-width:320px) and (max-width:480px) {
#image-wrapper{
float: none !important;
}
#image-wrapper img{
max-width: 80%;
display: block;
margin: 0 auto;
}
}
I also rebuild your .clearfix class to be more consistant and work in all browsers:
.clearfix:before,
.clearfix:after {
content: '\0020';
display: block;
overflow: hidden;
visibility: hidden;
width: 0;
height: 0; }
.clearfix:after {
clear: both; }
.clearfix {
zoom: 1; }
Take a look at the changes in the jsfiddle given.

Why my logo disappears when resizing my browser in firefox

I am currently building a standard html web page. I have a logo in the top right corner. When I resize my browser the logo disappears. It works like it should in all other browsers.
It seems to disappear when my browser is small enough to convey mobile versions and navigation stops being inline and is displayed block
i dont think its an html problem, as it works in other browsers so here is my css for the image.
img#logo {
margin-bottom: 10px;
color: #111111;
max-width: 100%;
width: auto;
height: auto;
}
Try adding a min-width. Change 300 to whatever works best. You can also use a min-width %. Like, 20%.
img#logo {
min-width: 300px;
}
edit:
Ok, now I see the real problem, its this
img#logo {
margin-bottom: 10px;
color: #111111;
max-width: 100%;
width: auto; // width auto...
height: auto; // height auto..
}
please change those to an actual value so you don't rely on varying browser defaults.
img#logo {
margin-bottom: 10px;
color: #111111;
max-width: 100%; // and you can remove this line
width: 100%;
height: 100%;
}
If that still does not work for you. Try removing the height line all together.

How do you make flexslider images responsive?

Currently, I am using width: 100% to make my image scale with the window size.
I would like to know how I can make the image scale down and not become distorted.
I simply changed the image width too width: 100% and changed height to height:auto to fix this for anyone that might need to know.
eg.
img {
width: 100%;
height:auto;
}
EDIT:
To ensure image widths don't go larger than their containers
img {
max-width: 100%;
width: 100%;
height:auto;
}
I did this and it worked out for me. I did not want the big slider on the homepage so i resized it, then i found out it was not responsive anymore. I added some codes and tested it, some did not work, some did. Finally this is the code to and resize the slider, and keep it responsive!!
.flexslider {max-width: 700px; margin: -20; padding: 0;}
.flexslider .slides > li {display: none; -webkit-backface-visibility: hidden;} /* Hide the slides before the JS is loaded. Avoids image jumping */
.flexslider .slides img {
display: block;
max-width: 100%; height: auto; margin: - auto;
}
}

How to uninclude sass mixin

I've this mixin applied on a menu, I don't want see on small resolution:
#mixin visuallyhidden {
position: absolute;
overflow: hidden;
clip: rect(0 0 0 0);
height: 1px; width: 1px;
margin: -1px; padding: 0; border: 0;
}
This working fine. But on bigger resolution I will show this menu. Obviously I can restyle and revert these attributes (I'm allready done it). But I was thinking if is there some built-in way to remove mixins – something like #uninclude visuallyhidden;.
Or is there a better way how to do this?
Thanks for all suggestions.
Use media queries to only apply the styles when appropriate. Doing and undoing bloats your CSS unnecessarily.
#media (max-width: 45em) {
.foo {
#include visuallyhidden();
}
}
