Why does using rgba color with an alpha value cause my div to become see-through?

Question

Why does using rgba color with an alpha value cause my div to become see-through?

I am currently attempting to assign a background color to a specific style of pop-up, but whenever I use a value that includes an alpha channel, it ends up being transparent. This is the CSS code I have been using:

--color: 255, 144, 106, 0.18;

background: var(rgb(--color))

If you're interested in seeing how this looks, you can view a screenshot here.

Is there a workaround that will allow me to maintain the color without making the div transparent?

Keep in mind that I am unable to modify the color token. I have attempted adjusting the parent's opacity and setting its background, but so far no success.

Answer №1

If you want to improve your color handling, consider updating your approach. Avoid setting transparency if it's not necessary.

To work around this issue, you can create multiple layers with a base layer in black or white:

.box {
 --color: 255, 144, 106, 0.18;
  
 background: 
   linear-gradient(rgb(var(--color)) 0 0)
   #fff;
   
 height: 200px;
}


body {
  background: linear-gradient(90deg,blue, red);
}

<div class="box"></div>

The alpha value controls the transparency of the color. The best way to adjust it is by modifying the alpha value itself. If you find that your div is too transparent, consider adding opacity: 1; in the styling.

Note: Upon reviewing an example provided, my initial answer may not apply. If you are unable to alter the color variable, your only choices are to accept it as is or attempt to create a new variable with a different opacity level to override the original color setting.

It appears that you've included the javascript tag.

An alternative solution involves using JavaScript to make adjustments since directly modifying the code is not feasible.

Although this method may have drawbacks like flickering during loading, it can help navigate constraints imposed by your system.

const container = document.querySelector("#container");
container.style.background = "lightblue";

#container {
  height: 120px;
  padding: 20px;
  background: rgba(173, 216, 230, 0.8);
}

body {
  background: white;
}

<div id="container"></div>

To ensure the correct syntax for defining RGBA values in CSS custom properties, use the following code:

--color: rgba(255, 144, 106, 0.18);

Make sure to utilize rgba() instead of rgb(). This will accurately set the background color while also specifying the alpha (opacity) value. By using the rgba() function, you are explicitly indicating that you are defining a color with an alpha channel, preventing the background from appearing completely transparent.

Below is the revised CSS code wth the corrected syntax:

--color: rgba(255, 144, 106, 0.18);

background: var(--color);
