CSS Toolbox

Three functions, one to return a CSS style object, one to create a new CSS rule, and one to delete a CSS style object. Dynamically create, change, and delete stylesheets. Easy to use and heavily commented.

Random Password Generator

This script can be used to generate random passwords for improved password strength.

Change Layer Colors

Use these two simple functions to change text and background colors within a specified layer without reloading the page. Can be used separately or together.

Automatic Copyright Update

Make sure your copyright notices are up-to-date. This script will automatically update your pages for you.

Date Selection Form

This handy script lets you auto-generate the day and year in a drop down selection as well as validate the date. Add it to your pages that require date validation.

Discover The Word Game

Discover The Word Game plays much like Wheel of Fortune. A sequential A-Z image button panel is provided to discover the word easily. You must guess using 5 tries or less. Includes over 200 words!

New to You

Use this cookie to show your visitors what's new on your Web site since their last visit.

Change HTML Tag Style

The following script allows you to change the style of an HTML tag. The style of the tag is referenced within the script by the tag's ID name.

Making Columns Render with Equal Height

A problem sometimes faced by Web developers is trying to get two (or more) columns in a multi-column layout to be the same height when the content is variable. Rather than using an arbitrary hardcoded value, the heights can be equalized (to the tallest one) with this script.

Last Modified (Advanced)

This script will display a default "last modified" date in the event the server is not able to configure it. A good backup solution.

Disable Text Selection

Use this script to disable the selection of text on a page. It's very simple using two of the built-in JavaScript events to cancel the selection before it starts. You can even attach the events to a specific element.

Expanding Text Images

This script creates a message using expanding text images. It's as simple as creating your own text images to say whatever you need.

Link Listing

Display a list of the links on your Web page. Using CSS, you can select which ones to display. The list includes the URL and link title. Useful as a cross-reference listing. You will need to add the 'title' attribute and 'class="link"' to each link you want displayed.

Image Upload Preview

This script is intended for forms where the user needs to upload an image to a Web site. The image is displayed on the page for previewing before uploading. The display will be resized if needed so as not to break the page layout. Valid file types are set in the script; others will be disallowed. Works only in Internet Explorer but degrades gracefully.

Daily Welcome Cookie

This script sets a cookie, with an alert window that only comes up the first time you visit the page each day. Good for calling attention to daily specials and news updates. Can be configured to work in other ways also.
