FAQs on Styling with CSS - Part 23 - Transparent/Opaque Images Video Lecture - IT & Software
| 1. What is the difference between a transparent image and an opaque image? |  |
| 2. How can I make an image transparent using CSS? | |
Ans. To make an image transparent using CSS, you can use the "opacity" property and set its value to a decimal between 0 and 1. For example, "opacity: 0.5;" will make the image 50% transparent.
| 3. Can I make only a specific part of an image transparent? | |
Ans. Yes, it is possible to make only a specific part of an image transparent. You can achieve this by using an image editing software, such as Photoshop, to remove the background or select the desired area and save it as a transparent image format, such as PNG.
| 4. Are there any alternatives to using transparent images in CSS? | |
Ans. Yes, there are alternatives to using transparent images in CSS. You can use CSS properties like "background-color" and "rgba" to create transparent backgrounds or overlays. Additionally, you can also utilize CSS pseudo-elements like "::before" and "::after" to create transparent shapes or elements.
| 5. How can I ensure that my transparent images are compatible with older browsers? | |
Ans. To ensure compatibility with older browsers, you can use a combination of techniques. One approach is to use CSS property "background-color" as a fallback for older browsers that do not support transparency. Another approach is to use JavaScript or a polyfill to add transparency support to older browsers. Additionally, providing alternative non-transparent versions of the images can also help maintain compatibility.

welcome to w3schools CSS image opacity
or transparency tutorial creating
transparent images with CSS is easy just
use the opacity property from css3
this is a regular image and this is the
same image with transparency let's look
at the code all major browsers use the
opacity property for transparency the
opacity property can take values from
zero point zero to one point zero a
lower value makes the element more
transparent and the higher value makes
the element less transparent Internet
Explorer 8 and earlier versions use
filter:alpha opacity this can take a
value from 0 to 100 where 0 is full
transparency and 100 is no transparency
for these images we've used two pseudo
class hover to change the transparency
when you mouse over the images let's
look at the code the first CSS rule is
very similar to the code within example
1 in addition we've added what should
happen when a user hovers or Mouse's
over one of the images in this case we
want the image to not be transparent
when a user hovers over it
CSS for this is opacity equals 1.0 for
Internet Explorer 8 and earlier its
opacity equals 100 so when we mouse over
the image is not transparent but when
the mouse pointer moves away from the
image the image will be transparent
again
and changed values set the default do
not be transparent and when we hover
over the image it's very transparent
like this
here is some text placed in a
transparent box the source code looks
like this first we create a development
class equals background set this to a
fixed width and height set a background
image these flowers and a border then we
create a smaller div inside the first
development set this class to trams box
for transparent box as fixed width and
height a margin white background color a
border and it's transparent inside the
transparent div we have a P element with
some text in it the text is a bit hard
to read so let's make the transparent
div a little less transparent how the
text is easier to read
this concludes our tutorial for CSS
