I am trying to use sprite image to optimise my website.
I uses png format for my image, and the image is like this:
My code css is like this:
.bg-upperbar_1 {
width: 55px; height: 55px;
background: url('../../assets/img/home/spritesheet.png') -10px -10px;
}
My html is like this:
<a class="home-upperbar home-top" href="<?php echo site_url('products/collection_watches'); ?>">
<img class="bg-upperbar_1">
</a>
But when I try to load my page, I'm getting a border for the picture even though the picture is png, like this:
How to solve this problem?
The reason you are getting a border is because your <img> doesn't have a src attribute set. If you want to use a sprite sheet as a background image, then you have to attach it to the <a> tag.
.bg-upperbar_1 {
width: 43px;
height: 45px;
background: url(https://www.w3schools.com/css/img_navsprites.gif) -47px -42px;
}
a{
display:block;
}
<a class="home-upperbar home-top bg-upperbar_1" href="<?php echo site_url('products/collection_watches'); ?>">
</a>

I am unable to get the section of the image I want from a collection of images.
I generated this CSS from http://spritepad.wearekiss.com
.search_img1{
background: url(/images/FBImages/1.png) no-repeat;
width: 16px;
height: 16px;
}
.search_img1 {
background-position: -152.98749923706055px 0;
}
The Img tag is :
<img id="search" src="images/FBImages/1.png" class="search_img1" title="search" alt="Seach" autocomplete="off">
I figured out the mistake I was doing. I had mapped the background image twice.
One at the time the img tag is desgined. and the other throughts its class [search_img1]
I just need to replace the following code to use the awesome font instead a background image. The goal is replace a button inside wordpress theme.
This is inside style.css
#et-social-icons .youtube .et-social-normal { background: url(images/YT.png) no-repeat 23px 23px; }
#et-social-icons .youtube .et-social-hover { background: url(images/YT-hover.png) no-repeat 23px 23px; }
#et-social-icons .youtube a:hover { background: #de2321; }
And here the part inside header.php to "show" the button:
<li class="youtube">
<a href="https://www.youtube.com/channel/UC3SNuSqLl09zS9IrxXswhIQ">
<span class="et-social-normal"><?php esc_html_e( 'Follow Us On YouTube', 'Nexus' ); ?></span>
<span class="et-social-hover"></span>
</a>
</li>
Thanks to all.

You can use pseudo-elements in CSS, :before and :after, like so :
.element:before{
font-family: FontAwesome;
content: "\Unicode";
}
And then position it however you want. You can find the unicode value for each icon by clicking on it, in the "icons" section of the FA website.
In my php page dynamically visualize the thumbnails. To make sure that these are all of the same size I do in this way
<a class="zoom" href="...">
<img src="thumb/default.png" width="130" style="background-image:url(thumb/<?php echo $images_jpg;?>);" class="centered" />
</a>
CSS
img.centered {
background-repeat: no-repeat;
background-position: center center;
}
/* 1 attempt */
a.zoom:hover {
background-image: url(thumb/zoom.jpg);
}
/* 2 attempt */
a.zoom img:hover {
background-image: url(thumb/zoom.jpg);
}
I would like to display a different image on event: hover, but this does not work. How could I do that? thanks
You could always do it like this.
HTML:
<div class="image" style="background-image:url(http://www.randomwebsite.com/images/head.jpg);">
<div class="overlay"></div>
</div>
CSS:
.image {
width: 200px;
height: 200px;
border: 1px solid;
}
.overlay {
width: 100%;
height: 100%;
}
.overlay:hover {
background: url(http://1.bp.blogspot.com/-lJWLTzn8Zgw/T_D4aeKvD9I/AAAAAAAACnM/SnupcVnAsNk/s1600/Random-wallpapers-random-5549791-1280-800.jpg);
}
So here we have the image you are getting via PHP on top as a div. And inside we have the overlay, the image you want when a user is hovering. So we set that to 100% width and height so it takes up all of the parent div and set the hover.
DEMO HERE
In your example the <img> always lays over the <a> background-image.
To avoid that, you could hide the image on hover. But that is kinda ugly ;)
a.zoom:hover {
background-image: url(thumb/zoom.jpg);
}
a.zoom:hover img
{
opacitiy: 0;
}
try this
<img class="centered" src="thumb/default.png"/>
and jquery
$(".centered").attr("src","second.jpg");
I created a custom attribute with 10 options ( mix10, mix20 .... mix100). What I am trying to do is when I select mix10, to get "mix10" as a custom sticker on product thumbnail image. I have no clue how to add this custom attribute as a small CSS on the thumbnail image of products.
First of all your going to have to look at z-index the styling property and then you're going to need to get the attribute in relation to the image.
Create a simple div over your product image
<div id="mix-sticker" class="mix-sticker_<?php echo $_product->getAttributecode()?>">
<img YOUR PRODUCT IMAGE/>
</div>
Then for your CSS styling you'd need to do something similar to
#mix-sticker {
z-index:500;
width: 400px;
height: 400px;
}
.mix-sticker_1 {
background:url(../images/mix1.png) top left no-repeat;
}
Let's assume you want to put this sticker on the thumbnails in your category listing. Open up /app/design/frontend/[YOURPACKAGE]/[YOURTHEME]/template/catalog/product/list.phtml and find the section that outputs your thumbnail images. It will likely look something like:
<li>
<a>
<img />
<a>
...
</li>
What you will need to do is insert some code right inside the <a> link:
<?php $_product = Mage::getModel('catalog/product')->load($_product->getId()); ?>
<div class="sticker">
<?php if($_product->getData('mix')=='mix10'){echo '<span class="mix10">'.$this->__('Mix10').'</span>'; }
elseif($_product->getData('mix')=='mix20'){echo '<span class="mix20">'.$this->__('Mix20').'</span>'; }
elseif ...
?>
</div>
Added all your options as elseif statements.
Then, in your CSS file, add styling for those stickers. That file will likely be located at /skin/frontend/[YOURPACKAGE]/[YOURTHEME]/css/styles.css:
.sticker {
position: absolute;
left: -5px;
top: -5px;
}
.sticker > span {
font-size: 0;
text-indent: -77777px;
width: 75px; /*image size*/
height: 75px; /*image size*/
background: url(../images/mix10.png) no-repeat left top; /*image location*/
display: block;
}
.sticker > span.mix20 {background: url(../images/mix20.png) no-repeat left top; margin: 1px 0 0 1px}
...
Add styles for all the sticker options you used in your PHTML file and then make sure your images are loaded to the server.
Is it possible to center an image only trough setting a class to the img tag without side effects? The problem is the following: I have an anchor around an image. If I use the following CSS
.aligncenter {
clear: both;
display: block;
margin-left: auto;
margin-right: auto;
}
And this (stripped down) HTML:
<a href="/path/to/image.jpg" class="fancybox" rel="fancybox" title="System">
<img src="/path/to/image.jpg" title="System" class="aligncenter">
</a>
the link takes the whole width of the main div. This means not only the image is clickable - also the space around the image (actually the whole width) is clickable. This is through the CSS display: block.
How can I center an image without using a parent div? I don't want the whole area clickable.
Background:
You can read this topic. It is about Wordpress and the built in editor. He automatically generates the class aligncenter on an image (if the user pressed the center button). I need this for my own theme. According to the moderators there this should be only a CSS question and doesn't have to do with changing code in Wordpress.
in aligncenter class add text-align:center
.aligncenter {
clear: both;
display: block;
margin-left: auto;
margin-right: auto;
text-align:center;
}
I'm not familiar with wordpress, but you might want to try setting the image's and the anchors's css 'display' property to 'inline-block'.
If you are limited in changing the document's DOM, another option is adding an 'onClick' attribute to the image.
This will allow you to run some function once the image is clicked.
So, for example, if you want to redirect to another page:
<img src='myImg.png' onclick='myRedirect()' style='cursor:pointer'/>
And in the page's header:
<script type='text/JavaScript'>
var myRedirect = function(){
window.location.href = 'Some other location';
}
</script>
Notice the style='cursor:pointer', which changes the mouse's cursor to a 'hand' cursor.
To avoid an additional div container or even JavaScript, you can make the anchor display as a block:
.logo {display: block; height: 115px; margin: 0 auto; width: 115px;}
/* height and width must equal your image's values */
<img src="logo.png" alt="Logo" />
Live demo: http://jsfiddle.net/performancecode/Ggk8v/
it still incorporates a div, but the way i do it is:
<div class="megaman">
<img src="img/megaman.jpg" alt="megaman">
</div>
img {
height: 125px;
width: 200px;
}
.megaman{
text-align: center;
margin: 0 auto;
display: block;
}
And yes, I replaced .logo with .megaman because megaman rocks! But it should work. I couldn't figure it out without using a div.
The solution I found. Adding /></a> and width and height to the anchor tag cuts down the hyperlink to the image...
<a class="link" href="URL" target="_blank"> <img width="75px" height="75px" alt="Facebook" src="IMAGE LOCATION"/></a>
Second answer:
paste this in functions.php
add_filter('image_send_to_editor','give_linked_images_class',10,8);
function give_linked_images_class($html, $id, $caption, $title, $align, $url, $size, $alt = '' ) {
// only do this on center
if($align == 'center') {
$html = str_replace('aligncenter', '', $html);
$html = '<p style="width: 100%; text-align: center;" >'.$html.'</p>';
}
return $html;
}
Down side, this won't effect already inserted images...
Also if you can please move the style of the <p> to the stylesheet.
