Make Background Color Transparent

Start by creating a div with a background image. Then add another div that sits over the div with background image.

<div class="back-container">
  <div class="overlay">
    Text Above Background Image
  </div>
</div>
.back-container {
  background: url("party-place.jpg");
  padding: 100px 0;
  background-repeat: norepeat;
  background-position: center;
  text-align: center;
  color: #1864ab;
  font-size: 1.7em;
  font-style: bold;
}

.overlay {
  margin: 0 50px;
  padding: 20px 10px;
  background-color: #edf2ff;
}

You may notice that the div blocks the background image.

To make the background transparent can use the following methods:

1. Background with Transparent Value

CSS has a color property called transparent. If you apply it to the background of a div, the HTML element’s background will become transparent.

background: transparent;

2. Using Color Values With Transparency(RGBA and HSLA)

You know that you can set the background color of a div using hex color code(#f0f0f0). Hex color code does not contain a transparency value. But you can also use RGBA and HSLA color codes.

To use your current hex color, first convert it to either rgba() or hsla() value.

.overlay{
  /*Hex color value*/
  background: #2b883d;
  /*rgba() color value*/
  background: rgba(43, 136, 61, 1);
  /*hsla() color value*/
  background: hsla(132, 52%, 35%, 1);
}

Result

You can convert hex color values using a simple color converter.

To add transparency to the rgba() color code, change the fourth value. It must be a value between 0 and 1. 0 is full transparent and 1 is fully opaque.

.overlay{
  background: rgba(43, 136, 61, 0.5);
}

To get the transparency for hsla() color code, change the fourth number to a value between 0 and 1. 0 is full transparent and 1 is fully opaque same as that of rgba().

.overlay{
  background: hsla(132, 52%, 35%, 0.5;
}

Using Background Color Transparent

The easiest method to make the background totally transparent is to use a transparent color value on the background.

.overlay{
  background-color: transparent;
}

The background color shown is that of the element below it.
