I'm struggling with making the background images on my website responsive. I have already added media queries to my page, but they seem ineffective and I am unsure of what else to try. Below are the HTML and CSS codes for the three images. Any suggestions or advice would be greatly appreciated. Thank you!
body {
background: url(/img/sect-bkgrd.jpg) center/cover fixed no-repeat;
font-family: 'Roboto', sans-serif;
color: #000;
}
#header {
min-height: calc(100vh - 94px);
background: linear-gradient(to right, rgba(0, 0, 0, 0.3), rgba(0, 0, 0, 0.3)), url(/img/sushi-main.jpg);
background-position: center center;
background-size: cover;
background-attachment: fixed;
background-repeat: no-repeat;
background-color: #000;
}
#menu {
background: linear-gradient(rgba(255, 255, 255, 0.2), rgba(255, 255, 255, 0.2)), url(/img/menu-bkgrd.jpg) center/cover fixed no-repeat;
