Layouts are the base of the theme, through which all templates are rendered.
Layouts are Liquid files that allow you to include content, that should be repeated on multiple page types, in a single location. For example, layouts are a good place to include any content you might want in your
<head> element, as well as headers and footers.
You can edit the default
theme.liquid layout, or you can create multiple custom layout files to suit your needs. You can specify which layout to use, or whether to use a layout at all, at the template level.

.liquid files, so content can be built using standard HTML and Liquid.
Layouts can access any global Liquid objects and can contain the following Liquid objects:
content_for_headerAnchor link to section titled "content_for_header"
content_for_header object is required in
theme.liquid. It must be placed inside the HTML
<head> tag. It dynamically loads all scripts required by Shopify into the document head. These scripts are required for features like reCAPTCHA, Shopify apps, and more.
You shouldn't try to modify or parse the
content_for_header object. If
content_for_header changes, then the behavior of your Liquid will change.
content_for_layoutAnchor link to section titled "content_for_layout"
content_for_layout object dynamically outputs the content for each template. You need to add a reference to this object between the
</body> HTML tags.
When working with layout files, you should familiarize yourself with the following concepts:
