Using a CSS-animated DIV as a background with a transparent background DIV overlaid with content on top

In my attempt to overlay bootstrap/html/css on a CSS animated starfield background, I'm encountering some challenges.

Online resources suggest using a 1x1 pixel png, but I am looking for a method to implement transparency through coding.

Using background: rgba to adjust alpha, opacity:0, and z-index:-1 have all proven unsuccessful in achieving the desired effect.

I have spent some time tinkering with it, and you can view my progress on Codepen:

My goal is to have the stars visible through the text-containing Div, the left Div of the quote box, and the Div with the buttons. Unfortunately, all I see is a black background.

Answer №1

In my experience, creating this code is relatively straightforward, although it may seem a bit complex at first glance. To start, we need to use a <div> element for the background. Assign it an id or class that indicates its position above the Star Field background. In your CSS, target the new <div> and set its background-color to transparent. This will essentially make it an invisible layer that can be displayed on top of other elements. Then, place your content inside this new <div> layer. Your HTML structure should resemble the following:

 <div id="starFieldBackground">
     <div id="background">
         <p>Insert Your Code Here</p>
     </div>
 </div>

Here is the corresponding CSS:

 #background {
     background-color: transparent;
 }

Make sure to specify the width and height of the <div id="background">. Alternatively, achieving this effect can also be done with z-index positioning, although it will require additional code.

Additionally, consider exploring the background-color properties in further detail:
