Template Terminology

In WordPress themes, the term 'template' is used in several different ways:

• The template file exists in the theme and indicates how your site will be displayed.
• Page templatesUsed on a single page to change the appearance of a page, which can be applied to a page or article.
• Template Tagsis a built-in feature of WordPress that allows us to fetch and display data using template tags (e.g. the_title(),the_content() ). 
• Template Hierarchyis the logic WordPress uses to determine which theme template file to use, depending on the requested content.

WordPress themes consist of template files which are containing HTML.Template Tagsand PHP code in PHP files.

Template file

When building a theme, we use template files to implement the layout and design of various parts of the site. For example, we can use the header.phpTemplate design website header using comments.phptemplate to design article comments.

When a user visits a page in our website, WordPress loads a template based on the page the user visited. The content displayed by the template file consists of the template file associated with theArticle TypeDetermine. The template hierarchy describes which template file WordPress will load based on the type of request and whether or not the template exists in the theme. The server then parses the PHP in the template and returns the resulting HTML content to the visitor.

The most critical template files are index.php , if a more specific template cannot be found in the template hierarchy, then all requests will eventually be sent to this template. Although there are only index.php Templates will work just fine, but themes usually include some other templates to display different content in different contextual environments.

Template snippet

A template snippet is a template that is used to be included in other templates, such as header.php. Template snippets can be embedded into multiple templates, thus simplifying theme development. Common template snippets are:

• header.php: Used to display the website header
• footer.php: For displaying the website footer
• sidebar.php: For displaying the site sidebar

Although a template snippet is only a part of a template, we can create any number of template snippets and include them in other template files.

Using Template Files

For example, in index.php, we can include other files:

• To include the header, use the get_header()
• To include a sidebar, use the get_sidebar()
• To include a footer, use the get_footer()
• To include a search form, use the get_search_form()
• To include custom template fragments, use the get_template_part()

The following is an example of using the template function to include other template fragments in one template:

More information about template tags can be found in the Template Tags section.

Main Style File

style.css is a style sheet (CSS) file required by every WordPress theme. It controls the appearance (visual design and layout) of the website pages.

File Location

For WordPress to efficiently recognize the theme, the style.css file needs to be located in the theme's root directory, not in a subdirectory.

For more detailed instructions on how to include style.css files in your theme, see theIncludes CSS and JavaScript filesThe "Style Sheets" section of the

fabric

WordPress uses the header comments section of style.css to display information about the theme in the Appearance (Theme) dashboard panel.
