A WordPress theme includes templates and layouts used to define the appearance and display of a WordPress blog or website. The good thing about these themes is they can be modified, managed, and added from the WordPress admin area under Appearance » Themes. These WordPress blog themes can provide much more control over the look and presentation on your website. A WordPress theme has multiple files that together produce a graphical interface with an underlying unifying design for a website. These files are called template files. A Theme adjusts the way the site is shown, without changing the hidden programming. Themes may include customized template files, image files jpg, gif, style sheets css, custom Pages, as well as any necessary code files php. Themes are categorized into two categories i.e. free WordPress blog themes and Paid WordPress blog themes.
Free WordPress themes can be downloaded either through WordPress store or other sources. The best thing about a free WordPress blog theme is the price, it is free, you can basically download the theme you need and begin using it. Some free ready-made WordPress themes meet an exceptionally high-quality standard. Moreover, the themes from the actual WordPress directory are updated on regular basis and are tested for privacy and security. Free WordPress themes are absolute free to download however there may be charges included to use extra features or purchasing a paid version.
The paid themes are widely used by professional bloggers and companies building a business website. The reason is simple; they provide much more control, functionalities and features than free ones. Paid WordPress themes look more elegant and organized. Most premium themes will give you option to select the skin, color and layout that suits you.
