Terse Markup and CSS for Aligned Form Labels and Inputs
18 April 11 09:46 PM | Scott Mitchell | 3 comment(s)

Like many ASP.NET developers, I am most comfortable working with C# and VB. I know just enough HTML and CSS to be dangerous. I know enough to implement the overarching page layout without using <table>s and instead to use CSS to position, size, and float the elements on the page, but when it comes to certain user interface designs within a page I’m quick to use <table>s. For instance, if asked to create a contact form like the one pictured below, my first inclination would be to use a trusty <table>.

AlignedUI

Recently, my friend and colleague Dave Yates showed me a website he had helped design and implement, StonehengeStyle. I was particularly interested when Dave showed me the contact page, which contained very clean, terse, readable markup without the use of <table>s.

First, each right-aligned text label – Name, Phone, and so on - is implemented as a <label> element. The input elements for collecting the input are simply <input>, <textarea> or <select> elements. For example, the markup for the Name, Phone, and Email Address inputs follows. (Note: I removed the required indicator for brevity; view the contact form’s markup in your browser for the complete markup.)

<label for="name">Name</label> 
<input name="name" type="text" id="name" class="textfield" /> 

<label for="phone">Phone</label> 
<input name="phone" type="text" id="phone" class="textfield" /> 

<label for="email">Email Address</label> 
<input name="email" type="text" id="email" class="textfield" /> 

Couldn’t be simpler, right? No filler <br /> or <p> elements, no <table>s cluttering things up. Heck, no <div>s, even.

The layout of the <label> and <input> elements is handled in the CSS via the following rules. First, all <label> elements are styled such that they are 180 pixels wide with 3 pixel padding on the top, 10 pixel padding on the right, and 2 pixel padding on the bottom. Their text is right-aligned and they clear left floating elements, which is why each <label> appears beneath the one above it.

label {
    clear: left;
    float: left;
    padding: 3px 10px 2px;
    text-align: right;
    width: 180px;
}

The textfield, textarea, and selectlist CSS classes, which assigned to <input>, <textarea>, and <select> elements in this contact form, specify a width of 250 pixels with a bottom margin of 8 pixels.

.textfield, .textarea, .selectlist {
    font-family: Arial,Helvetica,sans-serif;
    font-size: 12px;
    margin: 0 0 8px;
    width: 250px;
}

And that’s all there is to it! Pretty simple and straightforward.

This may not be terribly exciting for seasoned web developers or designers, but for someone like me, with just a working knowledge of HTML and CSS, this markup/CSS pattern is a gem and is how I’ve started doing my contact forms and other similar in-page layouts.

Happy Programming!
