What is the color code for transparency in CSS?

Question

Can anyone tell me what is the color code for transparency in CSS like white = "#FFFFFF"? As I am using following code, to convert the color codes into int:

Color color = ColorTranslator.FromHtml(hex);
return (int)((color.R << 16) | (color.G << 8) | (color.B << 0));

There is none. The RGB model does not include transparency. There needs to be a fourth channel for it. – Premundane

Answer 2

There is no hex code for transparency. For CSS, you can use either transparent or rgba(0, 0, 0, 0).

Answer 3

Or you could just put

background-color: rgba(0,0,0,0.0);

That should solve your problem.

Simply choose your background color of your item and specify the opacity separatly:

There is no transparency component of the color hex string. There is opacity, which is a float from 0.0 to 1.0.

Answer 7

There are now 8-digit hex codes in CSS4 (CSS Color Module Level 4), the last two digit (or in case of the abbreviation, the last of the 4 digits) represents alpha, 00 meaning fully transparent and ff meaning fully opaque, 7f representing an opacity of 0.5 etc.

The format is '#rrggbbaa' or the shorthand, '#rgba'.

Support is lacking for MS browsers, they might be less cooperative or just slower than the other developers, either or both of which actually sealed IE's fate: https://caniuse.com/#feat=css-rrggbbaa

In the CSS write:

.exampleclass {
    background:#000000;
    opacity: 10; /* you can always adjust this */
}

opacity: 1; is already 100% - 0.5 means 50% and so on. – Unkindly

Answer 11

Simply put:

.democlass {
    background-color: rgba(246,245,245,0);
}

That should give you a transparent background.
