Font Inheritance Issue in Fields

In an HTML document, certain elements may not inherit the font style defined for their parent element. This can be observed for fields, as illustrated in a specific example:

<label class="adm" for="UserName">User name</label><br><input class="adm" id="UserName" name="UserName" size="30" type="text" value="" />

If CSS is applied to inherit the font family from the element to these form elements:

body,html { font-family: Verdana,Arial,Helvetica,sans-serif; margin:0; padding:0; color: #111;}<br>label.adm  { font-size:0.9em; margin:0 0 3px 3px; display: block;}<br>input.adm  { font-size:0.9em; margin:0 0 3px 3px; }

Firefox renders these elements with different fonts. While the element inherits the Verdana font as expected, the field surprisingly displays a different font, "MS Shell Dlg".

This discrepancy arises because the element does not inherit the font family by default in all browsers. To explicitly force inheritance, CSS can be used:

input, select, textarea, button{font-family:inherit;}<br>

By incorporating this rule, the field will inherit the font family from its parent element, ensuring consistency in font style. A live demonstration of this solution can be found at http://jsfiddle.net/gaby/pEedc/1/.
