Okay, this is a massive CSS snippet defining a lot of custom properties (variables) and styles, likely for a WordPress theme. Let’s break it down into sections and explain what it does.
1. Custom Properties (CSS Variables)
The first large block defines a ton of custom properties, starting with --wp--preset--. These are essentially named values that can be reused throughout the stylesheet.This is a modern CSS practice that makes themes more maintainable and customizable.
* Gradients: A large number of gradients are defined. each one is a linear-gradient with specific colors and angles (135deg). These gradients are named with descriptive names like “vivid-orange-to-vivid-red”, “cool-to-warm-spectrum”, etc. These will likely be used for backgrounds, borders, or other visual elements.
* Font Sizes: --wp--preset--font-size--small, --wp--preset--font-size--medium, etc. define different font sizes.
* Spacing: --wp--preset--spacing--20, --wp--preset--spacing--30, etc. define different spacing values (padding,margin) using rem units (relative to the root font size).
* Shadows: --wp--preset--shadow--natural, --wp--preset--shadow--deep, etc. define different box-shadow styles. They use rgba to specify color with transparency.
* Colors: While not explicitly named as “colors” in the variable names, the has-* classes (explained later) rely on variables that are implicitly defined through the gradient definitions.
2. Layout Styles
This section deals with how elements are arranged on the page.
* :where(.is-layout-flex) and :where(.is-layout-grid): These selectors target elements with the classes is-layout-flex and is-layout-grid. The :where() function is used to reduce specificity, meaning these styles are less likely to be overridden by other more specific rules.
* gap: 0.5em;: Sets a gap between items in flexbox and grid layouts.
* body .is-layout-flex and body .is-layout-grid: These selectors apply display: flex and display: grid respectively to elements with the specified classes within the body of the document.
* .is-layout-flex > :is(*, div) and .is-layout-grid > :is(*, div): These selectors target all direct children of elements with the is-layout-flex or is-layout-grid classes.The :is(*, div) selector matches any element ( * ) or a div. margin: 0; removes the default margins from these children.
* .wp-block-columns.is-layout-flex and .wp-block-columns.is-layout-grid: These selectors target WordPress block columns that are using flexbox or grid layouts. They also set a gap of 2em.
* .wp-block-post-template.is-layout-flex and .wp-block-post-template.is-layout-grid: These selectors target WordPress post templates
