I am not very experienced with image sprites so here is the question..
I made an image sprite on the web; this is the code:
.sprite-slidebutton {
background-position: 0 0;
width: 70px;
height: 63px;
}
.sprite-slidecross {
background-position: 0 -113px;
width: 70px;
height: 63px;
}
The image I got, I downloaded to my page and I called the .png wherever wanted it. It does appear! And the sprite is working, the image is switching like i want it to..
But the PNG is not showing a transparent background :S also the image is not in the middle, I only see half of the both images.. where and how to adjust?
To see it live:
solved
If i had to guess i would say there is a problem with the alpha values in the image. Download gimp and see what they are.
the png probably has a white background, instead of a transparent background. that's something you will need to edit in photoshop, gimp or similar.
as far as only seeing half the image it might be due to the element you are assigning the class to. if its an inline element like <a> or <span>. try adding "display:block;" inside the sprite-slidebutton class.

i have a question about image re-sizing.
is there any way to resize photos with css or php without cropping them?(woocommerce cropping feature is not the way) Also I have tons of photos already published in my website and to resize them one by one would be pain in the...
What should i do to fix this problem ?
example of what i got
https://i.imgur.com/8tKmbrA.png
tried
img {
width: 30%;
height: auto;
}
I followed the instructions here to show already existing files on the dropzone area.
The problem is that the files appear cropped. See this image:
How should I go about fixing this? Has someone else seen this as well?
I fixed it by adding this css selector:
.dropzone{
.dz-preview{
.dz-image{
img{
height: 120px;
width:120px;
object-fit: cover;
}
}
}
}
The thumbnail you provide must be square.
Unlike what seems to be the behaviour of the newly dragged images, for added files, Dropzone will scale the picture and attempt to fit it in the image. That means if your image is wider than it is tall, you may see white space like the image shown in the question.
I created a shape (a rectangle to be exact) and in this shape I wish to have an image overlapping its actual size (e.g the rectangle would be 400px by 400px and the image would be 600px by 600px).
Are there any ways of doing this? Here's a mockup of what I'm describing:
EDIT: To achieve this, simply use
z-index: 1;
position: absolute;
Thanks user acarlon.
I am not 100% sure what you are after, but it sounds like you want an image cropped to a container div.
What you want is overflow: hidden on the container div. See here for details.
You can also use clip. See here.
Update
Actually, it seems like you want one image to overlap another. In which case you want to use absolute positioning and z-index. See here.
I'm quite new to CSS and web programming. What I'm trying to do is add a hovering effect for a button. I'm doing this by using 2 images.
There is a button called download and in hover code I add:
.button:hover{
background-image:url(images/button2.png);
}
The problem is the button takes time to load ie: on hover there is a delay to show the button. How can i solve this?
EDIT: I tried using preloading,but there is also a kind of delay
div#preloadedImages
{
width: 0px;
height: 0px;
background-image: url(images/button2.png);
}
You should use an image sprite to get rid of the delay. A sprite is one larger file that contains multiple images. Your button will have it's background set to sprite.png file. You can then change the background-position property to shift the positioning of your sprite.
On the other note - why do you use images for buttons? Most buttons can be done in pure CSS with some fallbacks for older browsers.
Create a single image out of the two images (which is called a sprite)
Here is a working example with an animation as well to show you how it works.
Click here >>> FIDDLE
Then set your background position to to show the normal state of the background image
.button {
width: 150px;
height: 50px;
background-image: url('image-sprite.jpg');
background-position: left top;
}
Then on your hover css, just move the background image to show the lower part of it
.button:hover {
background-position: left bottom;
}
Keep your current css and other stuff as they are and add an <img> component at anywhere of your page and make it hidden to load the image initially.
<img src="images/button2.png" style="display:none;"/>
I am making a website in Joomla.
And on my front page I have some images, which are links.
I want these images a's to get a slightly green effect, like opacity + green and stil have the original images below.
Is this possible to do with only css?
I can get the opacity to work, but not the green color.
Hope some one can help me.
Here is my site. it is the the small images under "Referencer" and "Nyheder"
This is doable with CSS. The main trick is that the links currently aren't surrounding the img block because their display type is inline.
Assuming the following HTML:
<img src="..." />
This is the CSS you need:
a.greenish {
background: green;
display: inline-block;
}
a.greenish img {
opacity: 0.5;
}
Adjust green and opacity to taste, obviously.
See this lovely jsfiddle for an example. Note that this includes addition CSS in case you only want it to turn green when hovered.
You won't be able to do what you want with pure CSS easily. There is no "overlay" in CSS. You can manipulate the background color/opacity, but the image would always be on top of that so it would not achieve the effect you want.
What you will need to do is to make the image the background of the A, then change the background do a similar image with the effect already applied. The images are small so you could easily make them sprites with the over look all in the same image.
