Mashable is one of the most popular tech blog today. They have a team of WordPress developers always working on the site to make the layout and features user friendly.
A shortcut to optimize your site’s user interface is to use a WordPress theme that looks like Mashable. I am not talking about a mashable clone theme here, because that will get you into trouble as the mashable design is their property. Also, using a theme exactly like mashable is also not good for long term branding of your website.
What you should do is to use a WordPress theme similar to Mashable design. Since the design of Mashable is constantly evolving, you need to use a theme that have the most common features of all Mashable designs. And that theme is FreshLife theme from Theme Junkie.
The theme has most of the features of the Mashable website and is very user friendly. I used it on one of my client’s website and the subscriber count skyrocketed. So, it does works.
The theme comes with all the features of a standard premium WordPress theme. You can configure almost everything from theme options page. It creates thumbnails automatically, and you can change the thumbnail dimensions easily from theme options.
So, if you are looking for a Mashable like WordPress theme, than FreshLife is best choice.
