In this lesson, we will create a CodeIgniter library that allows us to generate data grids automatically for managing any database table. I’ll explain each step required to create this class; so you’ll likely learn some new OOP techniques/concepts in the process!

As a bonus, we’ll proceed to write some jQuery code that will enable a user to update the data grid’s content without having to wait for a page refresh.

Please Note…

This tutorial assumes that you have a modest understanding of the CodeIgniter and jQuery frameworks.

A lot of developers think that CSS is a complete pushover to master. While it’s true that the ceiling is a little lower compared to others, it can still make you want to tear your hair out!

In this month’s quiz, you’ll be testing out your mastery of how CSS rules are applied.

Quiz Scenario

This will be the HTML code against which the CSS will be tested. Have it opened up in another window if needed.

<div id=”main”>
<p id=”foo”>Something clever goes here</p>
</div>

As an alternative, here is the JSBin page.

The answer is the color of the text in the page after the CSS given in the question is applied. Simple as that!

Good luck, ladies and gentlemen! And let us know if there are any specific topics that you’d like covered in the upcoming quizzes.

When in search of inspiration, one recipe that tends to always produce successful results is to look at the world around you in a different light, so to speak. This flipped perspective can often lead our thinking and creative processes out of the box, as we see things differently than we normally would. Photographers are fantastic at doing this with a simple location change. By taking their subjects and submerging them in water, or seeking them out under the sea, photographers make some truly stunning captures.

Welcome to our inspirational showcase of underwater photography. These photographers provide a look at a world that we tend to not have access to, and they breathe new perspective into areas we regularly turn to for inspiration, all by taking their lens beneath the surface of the water. We hope you enjoy these often breathtaking … Read More »
