In previous articles I’ve shown how to set custom error messages for with CSS and JavaScript. Recently Estelle Weyl demonstrated a method that seems to have gone largely unremarked in browser and spec documentation: form validation customization by using the title attribute.

Playing With The HTML5 range Slider Input

Among the many new elements that HTML5 has introduced, range is perhaps the oddest but also the most generally useful. Previously requiring a great deal of coding or a framework to generate, you can now create a slide control natively in all modern browsers with a single element.

range is particularly useful for forms in which three conditions exist:

input Antipode: The HTML5 output Element

html / forms

Estimated reading time: 2 minutes

Of the many new features introduced by HTML5, only one element was designed to be the exact opposite of a tag that already existed: <output>, the logical companion to HTML’s <input>.

Originally designed to contain the results of a form calculation, the scope of the <output> element was expanded to make it useful for many purposes, not just traditional forms. However, like <progress> and other tags, <output> depends on HTML5’s close relationship with JavaScript: without the addition of some simple scripting, the tag doesn’t have a great deal of utility.
