now you can use rgba in CSS properties like this:
.class { background: rgba(0,0,0,0.5);}-
0.5 is the transparency, change the values according to your design.

Keep these three options in mind (you want #3):
1) Whole element is transparent:
visibility: hidden;-
2) Whole element is somewhat transparent:
opacity: 0.0 - 1.0;-
3) Just the background of the element is transparent:
background-color: transparent;-

To achieve it, you have to modify the background-color
of the element.
Ways to create a (semi-) transparent color:
.transparent{ background-color: transparent;}-
.semi-transparent-yellow{ background-color: rgba(255, 255, 0, 0.5);}.transparent{ background-color: hsla(0, 0%, 0%, 0);}
.semi-transparent-yellow{ background-color: rgb(255, 255, 0, 0.5);}.transparent{ background-color: hsl(0, 0%, 0%, 0);}
.semi-transparent-yellow{ background-color: rgba(255 255 0 / 0.5);}.transparent{ background-color: hsla(0 0% 0% / 0);}
.semi-transparent-yellow{ background-color: #FFFF0080;}.transparent{ background-color: #0000;}

Use color to transperant to bg , RGBA color values are an extension of RGB color values with an alpha channel - which specifies the opacity for a color.
An RGBA color value is specified with: rgba(red, green, blue, alpha). The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque). like you need black transperant background
h1 { background: rgba(255, 255, 255, 0.2); color: red; font-family: "Amarillo"; left: 0; position: absolute; right: 0; text-align: center;}
search the rgb colors and set opacity what ever you need to the last value
