leftmarginwas a non-standard extension for HTML by the browser provider. This was never standardized because CSS came about (almost two decades ago). Since it is not standard, it is not part of the XHTML 1.0 Transitional DTD.

Use CSS instead (for all attributes that you have in the body start tag in this example).

NB: Transitional DTD , HTML 3.2 Strict DTD. , , . HTML 5 ( ).

CSS , -:

<style type="text/css">
    body {
        margin: 0;
        padding: 0;
        background: #FFFFFF;
    }
</style>
