This lesson will further delve into how Jekyll themes work, how to switch between them, and how to troubleshoot common issues,
enabling you to effectively manage your site’s visual presentation.
Understanding Jekyll Themes
A Jekyll theme is a collection of layouts, includes, stylesheets, and scripts that define the look and feel of your website.
When you apply a theme, Jekyll uses these files to render your content consistently across all pages.
This modular approach allows for rapid development and easy customization.
Layouts: HTML files (e.g., default.html, page.html, post.html) that provide the overall structure. Your content is injected into these layouts.
Includes: Reusable HTML snippets (e.g., headers, footers, navigation menus).
Assets: CSS, JavaScript, and images that control visual design and interactivity.
Configuration: Theme-specific settings often defined in _config.yml or in the theme’s own configuration files.

Theme Switching Guide
Switching between Jekyll themes involves modifying your _config.yml file and ensuring that the necessary theme files are correctly referenced.
The process can be simplified using scripts or by directly editing the configuration.
