CSS Inheritance: An Introduction

CSS Inheritance: Simplifying Website Styling

Key Concepts:

CSS inheritance streamlines website styling. Parent elements pass properties to their children, minimizing repetitive code. However, not all properties inherit (e.g., border, background-image). The inherit keyword forces inheritance for non-inheritable properties. This applies to shorthand properties too, but missing sub-properties default to their initial values. DevTools visually highlight inherited, non-inherited, and overridden properties, simplifying debugging.

Think of it like family traits: tall parents often have tall children. Similarly, a parent element's color: green; usually makes its children green, unless overridden.

This article explores CSS inheritance's impact on element appearance.

Benefits of CSS Inheritance:

Inheritance significantly reduces development time. Imagine setting the color for every child of the tag manually! It's inefficient and error-prone. Inheritance maintains consistency without redundant code for properties like font-family or font-size.

Limitations of Inheritance:

Not all CSS properties inherit. If they did, styling would become chaotic. For example, inheriting border would create unwanted borders on all child elements. The following CodePen demonstrates this:

Forcing Inheritance with inherit:

Sometimes, you need a non-inheritable property to inherit. The inherit keyword enforces this:

.some-child {
  color: inherit;
}

This makes links inherit their parent's color:

p {
  color: #f44336;
}

ul {
  color: #3f51B5;
}

a {
  color: inherit;
}

Inheritance and CSS Shorthand:

Applying inherit to shorthand properties affects all sub-properties. However, you can't selectively inherit sub-properties within shorthand. For example, border: 1px solid inherit; is invalid.

To achieve this, use longhand:

.example {
  margin: 10px 0 20px 15px;
  margin-right: inherit;
}

Missing Shorthand Values:

Omitted sub-properties in shorthand revert to their initial values. For example:

.container-a {
  font: italic 1.2em/1.75 Lato;
}

.container-a p {
  font: bold 1em Lato;
}

The paragraph's font-style resets to normal, not inheriting the italic style. Use longhand (font-style) for precise control.

Using DevTools:

DevTools visually distinguishes inherited, non-inherited, and overridden properties. This simplifies troubleshooting layout issues.

Conclusion:

Inheritance simplifies CSS, reducing redundancy and improving maintainability. The inherit keyword provides control over inheritance. DevTools aid in debugging. Understanding inheritance is crucial for efficient web development.
