Reviewing nixon.com and craigslist.org
And so it continues...
Nixon.com
Nixon.com is a website made for the advertisement and sale of Nixon products, mostly accessories. However, I'm not here to discuss the purpose of the website, I'm here to discuss the responsive design (I'll review the purpose later). As far as responsive design, Nixon.com is indeed a very responsive website. Shrinking and enlarging the screen shrinks and grows the images and text respectively on the page. The design of this website is a masterclass example of quality responsive design and should be modeled everywhere.
Craigslist.org
Craigslist, on the other hand, is a website that lacks the responsive design commonly found on the modern internet. Of course, not every website is built the same and nor do they all require responsive design. Craigslist is a website that isn't made for looks, it simply is just built for users to quickly locate and purchase items from local sellers. As far as the deeper aspects of the site, I won't get into now, but the overall responsiveness is lacking at best.
Validation
Like most websites reviewed, Nixon.com has quite a number of errors and warnings according to W3C's Validator (here). And also just like the other websites, most of these warnings are either because of redundant tags and attributes or minor errors that don't break the page at all. On Nixon.com, there were 85 errors and warnings.
Now for Craigslist.org, there are significantly fewer warnings and errors, being only five of them. Just like with Nixon.com, these warnings and errors were simply just redundant info or attributes that aren't meant to be placed in a specific tag.
The Review
Now for the moment you've been waiting for... the actual numerical value I place on these websites that is completely subjective and a matter of my own opinion. Anyway, in terms of usefulness, I give Nixon.com a 9/10. It certainly does provide a simple yet complex design for its website that provides a solid ground for any user to use, regardless of browser or device. This connects directly to the usability aspect, which I'd rate a 9/10 as well because of the simplicity in the looks yet complexity in the design itself. Bravo, nixon.com.
Next, I rate the lowly craigslist.org. As far as purpose goes, It's a solid 8/10. Of course, a website like craigslist depends entirely on where the user is located, but if the user is in a populated area and is looking for cheaper options, this is the way to go. Now for the usability part. I'll give it a 4/10. The website's responsiveness is awful. There's essentially two sizes; mobile and computer. That's it. The design doesn't change at all if the width is above at least 400px. A website truly stuck in the early 2000s in terms of design.
