I am not sure how to change the background of an image tag in css. For example, I have a darker background in my webpage. Let's say I include an image of a purple X with a white background. How would I change the background of that purple X image to be the same color as my body.
You could add mix-blend-mode: multiply; to your <img>'s css. It will render the white 'transparent' but it'll also alter the other colors in the image.
Best solution would probably be to use transparent PNGs.

Shrimp image with transparent background
So I have an image of a shrimp with a transparent background. Meaning that when i render it it supposed to only show the shrimp and not the transparent background. I'm trying to render it in a webpage using html and css. How can I render the image in my webpage and making sure that the transparent background doesn't show it becomes transparent and shows whatever is behind the image other than the shrimp itself.
Thanks!
the background in your image is NOT transparent, it's just look like...
Your image is a PNG file but it does not have a transparent background. Try to use photoshop to remove the background. :)
I wonder is it possible to make transparent background for only 1 color of a png image.
For exemple if my image contains 2 colors red and blue, I wanna make transparent (or change opacity) only the red color.
No, you will need to use a img editor like adobe illustrator.
CSS will not do it for you.
I want to know if it is possible to affect the opacity of only a certain color in an Image?
For example, I have a PNG image file that has a simple drawing on it (smiley face) and I set the backdrop to the color 'white' only. I want to use the image on a web page, but I want only the smiley face shown (no white backdrop).
Is there a way to do this?
Not in HTML or CSS but what you should do is open the image in a picture editor that supports PNG transparency and set your image background to transparent (or opacity = 0) instead of white.
Not with CSS. The best way to handle this would be to give your smiley face image a transparent background. That way, you could put a colored element behind it whenever you want to change its color.
I have an image that has some white on the edges, and I want to change the background color of the div that the image is contained in. Now when I do this, I can still see the little bit of white surrounding the image, and it looks terrible.
Is there a way I can change the background color of the image to whatever the background color of the div is, and would this be the best way to do it? Or does it make more sense just to edit the extra white out of the image.
You should just fix the image.
If the image has a transparent background then you can change the background color the same way you would a div.
Edit You may also want to check to make sure there is no padding, borders, ect. that would cause this issue to happen
I want to have a box with two colors with silver on top and it should slowly fade into white, just as Apple's homepage background. How do i do that?
Thanks as always.
If you want to use CSS3 here's a great example: http://css-tricks.com/examples/CSS3Gradient/
W/o CSS3, you have to make do with an image repeated horizontally (x-repeat), similar to what tvanfosson said.
you are looking for gradient background?
http://www.tizag.com/cssT/background.php
look for "css gradient background"
there are more articles if you google: gradient background css
The basic idea is to use a background image that does the gradient for you. You sent the background color of the page to the "end" color of the gradient, then apply your gradient background image using CSS with a repeat in the opposite direction that you want the gradient to flow. So if you want a 100-pixel, silver to white, gradient from top to bottom you'd create a 100Hx1W pixel image that spans your colors from top to bottom. Set the background color to white and apply the background image repeating across the x axis. You can easily create the gradient using the gradient tool in Photoshop or GIMP.
