Simple CSS style for letting web page adjust according to browser size. Not perfect.

webwidth.css

    @media screen and (min-width: 1000px) {
    body {
    width: 960px;
    margin: auto;
    }
    }

    @media screen and (max-width: 1000px) {
    body {
    width: 95%;
    margin: auto;
    }
    }
