    border-bottom-width

    Summary

    The border-bottom-width CSS property sets the width of the bottom border of a box.

    Syntax

    /* Any <length> value */
    border-bottom-width: 10em;
    border-bottom-width: 3vmax;
    border-bottom-width: 6px;
    
    /* A keyword */
    border-bottom-width: thin;
    border-bottom-width: medium;
    border-bottom-width: thick;
    
    border-right-width: inherit;
    

    Values

    <br-width>
    Is either a non-negative explicit <length> value or a keyword denoting the thickness of the bottom border. The keyword must be one of the following values:
    thin
     
    A thin border
    medium
     
    A medium border
    thick
     
    A thick border
    The specification doesn't precisely define the thickness of each of the keywords, which is therefore implementation specific. Nevertheless, it requests that the thickness does follow the thin ≤ medium ≤ thick inequality and that the values are constant on a single document.
    inherit
    Represents the calculated value of the border-bottom-width of the parent's element.

    Formal syntax

    <br-width>

    where
    <br-width> = <length> | thin | medium | thick

    Examples

    element { 
        border-bottom-width: thin;
        border-bottom-style: solid;
        border-bottom-color: #000;
    }
