What is a WordPress theme?

They are tens of thousands of themes ready to be installed on your WordPress site. You may want to have a few customizations on your preferred theme or maybe you want to select a multipurpose theme to have a ton of customization options. Fundamentally, themes are a way to skin your WordPress site with a collection of files that work together. These files are called template files. They produce a graphical interface with an underlying design for your WordPress site.

Sometimes, the terms WordPress template and WordPress theme are confused together. Templates are used throughout WordPress themes. In fact, a WordPress theme is made up of template files. Also, when you are building your dedicated theme, you use template files. For example, you may use the index.php template file for loading and utilizing all of the WordPress files (you can use the index.php template file when home.php does not exist to render the blog posts index).

For creating a static webpage, we just need to use CSS and HTML. The former provides style while the latter provides the layout. Also, to present a page, WordPress uses PHP files to incorporate CSS, HTML, and many other resources. This lets users customize parts of pages. These files used for customization are template files.

Template files are reusable files used for building web pages. Some of them are used in specific situations while others are used on all of the pages (e.g. headers). It is important to note that WordPress uses several predetermined template files, the most common or frequently used of them are listed below:

  • Index.php: the main template file required for every theme.
  • style.CSS: the main stylesheet required for any theme. It also contains the header section related to comments. It controls the presentation of the website (visual design and layout).
  • home.php: is called for the front page by default.
  • header.php: it usually contains the document type of your site, Meta information, and links to stylesheets, scripts, and other relevant data.
  • single.php: is used to present a single post on a webpage
  • page.php: is used when visitors request individual pages. It can apply to a page section, a single page, or a group of pages determined by class.
  • archive.php: is used to present the posts by a date, an author, or a category.
  • search.php: is used for showing the search result of a user.

You can create a custom WordPress theme. In the past, you had to follow the WordPress codex and have basic coding knowledge. But today, anyone can generate a custom WordPress theme within an hour and with no coding know-how. When you want to create a WordPress theme, you decide how that content looks and displayed. For example, you decide about creating different layouts such as static or responsive, or using one column or two. So, for creating a custom theme, you’d better use a framework to build one. Many theme developers choose to build a WordPress theme with bootstrap. You may ask, why are WordPress themes developed using bootstrap?
