Web Forms


There are many ways to mark up a form, including using a table or the label tag. Take a look at these methods and tips to ensure your forms are structured so they benefit the user and the site owner. Also covered are some CSS techniques to customize the forms. (From the book Web Standards Solutions: The Markup and Style Handbook, by Dan Cederholm, from Apress, 2004, ISBN: 1590593812.)

Web Forms - Method B: Tableless, but Cramped
(Page 2 of 9 )

 
Method B: Tableless, but Cramped

FONT face="courier new, courier, mono" size=2><form action="/path/to/script" method="post">
 <p>
  Name: <input type="text" name="name" /><br />
  Email: <input type="text" name="email" /><br />
  <input type="submit" value="submit" />
 </p>
</form>
 

Using a single paragraph and a few <br/> tags to separate the items is a passable solution—but could visually render a bit on the cramped side. Figure 5-2 shows how this would typically appear in a browser.

You can see that while we got away without using a table, it looks rather cramped and ugly. We also run into the problem of the form controls not lining up perfectly, as seen in Figure 5-2.

We could alleviate some of the crowdedness by adding some margins to the <input> elements using CSS like this:

input {
margin: 6px 0;
}

The preceding would add a 6-pixel margin to both the top and bottom of each <input> element (the name, e-mail, and submit controls), spacing out the elements as seen in Figure 5-3.

While there’s nothing particularly wrong with Method B, there are a few adjustments we can make to build a better form. And those adjustments are evident in Method C. So let’s take a look.

Method C: Simple and more accessible
 
<form action="/path/to/script" id="thisform" method="post">   <p><label for="name">Name:</label><br />
  <input type="text" id="name" name="name" /></p>
  <p><label for="email">Email:</label><br />
  <input type="text" id="email" name="email" /></p>
 <p><input type="submit" value="submit" /></p>
</form>

I like Method C for several reasons. First off, for a simple form like this example, I find it convenient to contain each label and control in its own paragraph. When viewed unstyled, the default spacing of a paragraph should be enough to set the items apart in a readable way. Later, we could control precise spacing with CSS on <P> tags that are contained within our form.

We’ve even gone a step further and have given this form a unique, but boring, id="thisform". So, that precise spacing I was just referring to could go something like this:

#thisform p {
  margin: 6px 0;
   }

Essentially, we’re saying that all <P> tags within this particular form should have top and bottom margins of 6 pixels—overriding the default margins that the browser imposes on paragraphs in the absence of any styling.

Another difference that Method C has over the previous two is that while each group (label and field) are wrapped in <P> tags, a <br/>
puts each on its own line. Using a <br/> to separate the items gets around the issue of fields not lining up perfectly due to text labels of different lengths.

Figure 5-4 shows how Method C would appear in a visual browser, with the CSS applied to each <P> tag as mentioned earlier.

Aside from the visual aspects of Method C, let’s take a look at the most important advantages it has: in particular, an accessibility improvement.
