How to line up HTML input elements?

I tested this out in Internet Explorer 7, Firefox 3 and Safari/Google Chrome. I definitely see the problem with <select> and <input type="file">. My findings showed that if you styled all the inputs at the same width, the <select> would be about 5 pixels shorter in all browsers.

Using the Eric Meyer CSS reset script does not help this issue, however if you simply make your <select> inputs 5 pixels wider you'll get very good (albeit not perfect) alignment in the major browsers. The only one that differs is Safari/Google Chrome, and it appears to be 1 or 2 pixels wider than all the other browsers.

As far as the <input type="file"> is concerned, you don't have much flexibility with styling there. If JavaScript is an option for you, you can implement the method shown on quirksmode to achieve greater control over the styling of the file upload control.

See my full working example below in XHTML 1.0 Strict for a typical form with consistent input widths. Note that this does not use the 100% width trick pointed out by others here because it has the same problem with inconsistent widths. Additionally there are no tables used to render the form as tables should only be used for tabular data and not layout.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>
  <title>Example Form</title>
  <style type="text/css">
    label,
    input,
    select,
    textarea {
      display: block;
      width: 200px;
      float: left;
      margin-bottom: 1em;
    }
    
    select {
      width: 205px;
    }
    
    label {
      text-align: right;
      width: 100px;
      padding-right: 2em;
    }
    
    .clear {
      clear: both;
    }
  </style>
</head>

<body>
  <form action="#">
    <fieldset>
      <legend>User Profile</legend>
      <label for="fname">First Name</label>
      <input id="fname" name="fname" type="text" />
      <br class="clear" />

      <label for="lname">Last Name</label>
      <input id="lname" name="lname" type="text" />
      <br class="clear" />

      <label for="fav_lang">Favorite Language</label>
      <select id="fav_lang" name="fav_lang">
        <option value="c#">C#</option>
        <option value="java">Java</option>
        <option value="ruby">Ruby</option>
        <option value="python">Python</option>
        <option value="perl">Perl</option>
      </select>
      <br class="clear" />

      <label for="bio">Biography</label>
      <textarea id="bio" name="bio" cols="14" rows="4"></textarea>
      <br class="clear" />
    </fieldset>
  </form>
</body>

</html>

I usually put them inside a div or table cell (horrors! I know) of the width I want, then set the select and input style:width to 100% so they fill the div / cell they are in.

Solution 3

I found that if you set select and input element border and padding to 0, they are same width. (Tested on Chrome 14, Firefox 7.0.1, Opera 11.51, IE 9)

Putting 1px border/padding on select and input elements makes input element 2 pixels wider. For example:

<form class="style">
    <input name="someInput" />
    <select name="options">
        <option value="1">Value 1</option>
        <option value="2">Value 2</option>
    </select>
</form>

.style select {
    width: 100px;
    padding: 1px;
    border: 1px solid black;
}
.style input {
    width: 96px; /* -2 px for 1px padding(1px from each side) and -2px for border
    (select element seems to put border inside, not outside?) */
    padding: 1px;
    border: 1px solid black;
}

Solution 4

Other than width, I'd be setting border and margin too, these may or may not influence your controls. Something like this may help:

input, select {
    width: 100px;
    margin: 0px;
    border: 1px solid;
}

Ron has a good idea too.

I am hoping to find a resource for lining up input elements in a HTML page. I find it difficult to get a select element and a text box to be the same width even when using the width style attribute, and it is even more difficult across browsers. Finally, file inputs seem impossible to get to the same width cross browser. Are there any good guides or tips for accomplishing this? Perhaps there are some default CSS attributes I should be setting.
