Responsive layout testing

While working on a responsive website, testing it could be tricky. The usual way (and effective) is to resize the browser window and there’s many plugins on the browser that do just that. Another way is to use an available tools on the web, many of these are awesome, like The Responsinator and Screenqueri.es. Another one that is also my favorite is RWD Bookmarklet by Victor Coulon.

These were all cool and I frequently used it. However, these tools were made for testing on mobile and tablet display resolution, what if, you want to test a laptop or desktop resolution as well? In my case, I have 1280×800 laptop, so I never knew how the website will look on higher resolution screen. There’s also many display resolution on mobile now to consider, not just iOS resolution.

And so I created a simple tool to test responsive website, with a wide range of resolution to select, from mobile to tablet to desktop. Also HDPI display is common now, so I added a device pixel ratio selection that calculate the effective resolution. For example, Motorola RAZR have QHD display with pixel ratio of 1.5, so the effective resolution is actually 640×360, that is the resolution the phone display on it’s browser.

Feel free to use the tool here: responsive.jeffri.net

A little bit of disclaimer, I don’t store any data from your usage. There’s no trip to the server when you use it, at all. 🙂

Hope you find it useful! Cheers!

Pure CSS3 responsive navigation with :target

This is an experiment I tried when working on WPMUDEV mobile navigation a while back, basically to make the navigation work with CSS alone. Using :target pseudo-class, this is possible, but of course it won’t work very well on every navigation.

For the sake of this demonstration, I have made a responsive navigation that will scale between smartphone, tablet and desktop.

Background image on table row

Applying a background image on table row is a classic issue that never get right, at least not in a first few pages on Google search when I looked on a solution. In fact, the only cross browser solution is to apply the background to the table cells instead. But what happen if you want a repeated background across the table row?

The problem

Let’s say you wanted to apply a background to a row that has disabled class.

The CSS:

table tr.disabled {
	background: url('disabled.png') repeat-x;
	color: #aaa;
}

Result:

Ouch! The background is in fact applied to the table cell, not the table row as we intended. It looks ugly as the image start in every cell!

A little guide of using jQuery

JQuery is Javascript library that can help you write code smaller and easier to take a good care of event handling, animating, AJAX and more. With jQuery, we can make our webpages more beautiful. You can see that I used it for my side menu here. 🙂

This article didn’t intend to teach you how to became the jQuery master and I’m far away from a master. It just for the case you didn’t know about jQuery yet and want to start with it, then this will be a good guide for you. If you want a more complete tutorial, go to the jQuery documentation.
