Background Colors

Hello, I have a question: I have insert into my pages tables. I want to color the cells but I can’t. I have tried HTML <bg color= #b6bcb3> and CSS <tr style=“height: 54.2813px;”>

body {
    background-color: yellow;
}

h1 {
    background-color: #00ff00;
}

p {
    background-color: rgb(255,0,255);
}

I also want to color the background of my page but I can’t.
Thanks in advance.
