css - HTML elements to fill the widths of their table cells, but with a small & consistent bit of padding around -

-

answered own question. here answer:

table, th, td  { border:1px solid black; padding-left:4px; padding-right:4px; } input[type="text"], button, select                { width: 100%;                  -webkit-box-sizing: border-box;                  -moz-box-sizing:    border-box;                  box-sizing:         border-box; }

in webpage (source code below), several elements not fill widths of table cells: input text fields, grade selects, , insert button. desired result i each fill width of table cell, small bit of padding around it, delete button has around it.

i have tried various combinations of css styles, including 'width:100%', 'padding:2px', plus others. however, have have not been able obtain combination yield desired result. might know how can achieve desired result?

i using chrome version 33.0.1750.154 m, , html source code is:

<!doctype html> <html>   <head>     <meta charset='utf-8'>     <title>presidential grade</title>     <style>       table, th, td  { border:1px solid black; }       fieldset       { border-style:solid; border-color:red; display:inline-block; }       legend         { font-style:italic; text-align:center; font-weight:bold; }       select         { font-family:"lucida console", monaco, monospace; }     </style>   </head>   <body>     <form>       <div>         <fieldset>           <legend>&nbsp;presidential grade&nbsp;</legend>           <table>             <tr>               <th>action</th>               <th>                 &nbsp;last name<span style='color:green;'>&nbsp;&utrif;&nbsp;</span>               </th>               <th>&nbsp;first name&nbsp;</th>               <th>                 &nbsp;grade<span style='color:green;'>&nbsp;&utrif;&nbsp;</span>&nbsp;</th>             </tr>             <tr>               <td><button>delete</button></td>               <td>                 <input type='text' maxlength='20' size='7' value='adams'>               </td>               <td>                 <input type='text' maxlength='20' size='7' value='john'>               </td>               <td>                 <select>                   <option value='a'>a</option>                   <option value='b'>b</option>                   <option value='c'>c</option>                   <option value='d'>d</option>                 </select>               </td>             </tr>             <tr style='background-color:#d0ffd0;'>               <td><button>insert</button></td>               <td style='display:none;'></td>               <td>                 <input type='text' style='color:darkblue;' maxlength='20' size='7'>               </td>               <td>                 <input type='text' style='color:darkblue;' maxlength='20' size='7'>               </td>               <td>                 <select>                   <option value='a'>a</option>                   <option value='b'>b</option>                   <option value='c'>c</option>                   <option value='d'>d</option>                 </select>               </td>             </tr>           </table>         </fieldset>       </div>     </form>   </body> </html>

any element direct child of td, make 100 percent wide:

td > * {width: 100%;}

and add padding:

td {padding: 8px;}
