Answer 1

i assume you refer to the div elements with class="section"

you can add
opacity: 0.8; /* lower this value for more transperancy */
to
.section { .... }

Answer 2

You can add transparency with css property named "opacity"

#block {
opacity: 0.7;
}

opacity value ranges from 0 to 1.

Answer 4

- For set transparent or semi-transparent bg use
CSS background-color

background-color: transparent;
background-color:rgba(255,255,255, 0.6);

Latter set bg color as semi-transparent white with alpha to 60%

- for set complete block use CSS opacity:

opacity: 0.6;

This set global opacity for the element (not only background)
