Custom Post Type was introduced in WordPress 3.0 to allow the users to define different post type within a blog. For example, if you are a chef looking to open new cooking classes and also to share your recipes with others, you can define a post type call “Classes” where you announce the availability of new cooking class and another post type call “Recipe” and share your recipe with your readers.
WordPress doesn’t come with an easy way for the normal users to create custom post type, but luckily there is a useful plugin for that.
If you have noticed, one of the way that highly-trafficked site save bandwidths is to use a lazy load plugin. What this lazy load plugin does is to load the images only when they become visible on the screen. Any images below the visible screen will not be displayed. This is also known as on-demand loading.
In WordPress, there are several lazy load plugins that you can use. One of my favorite is the jQuery Image Lazy Load plugin, simply because it just works the moment you activate it. No configuration is required.
Apart from being a user-friendly CMS, what makes WordPress really great is the support for plugins and themes. With a huge library of plugins and themes, you can instantly add new features and new skins to your blog without any coding on your part.
However, if you have been blogging long enough, you will know that sometime a badly coded plugin can break the site. Worst still, it can even cause the site to crash. This goes the same for a new theme. Without any tweaking and configuration, 9 out of 10 times the theme won’t look great on your site. For such cases, it is wise to test them out before making them live.
