Scoped CSS is a technique that allows developers to encapsulate styles within a specific portion of HTML, limiting their effects to a particular section of the document. This method offers several advantages in managing styles and avoiding global style conflicts in web development.
What is Scoped CSS?
Scoped CSS is a feature introduced in HTML5 that enables the definition of CSS rules targeted to a specific section of HTML. It employs the
scoped attribute within a
<style> tag, restricting the defined styles to the elements within the same parent.
How Does Scoped CSS Work?
When using scoped styles, the CSS rules defined within a
<style scoped> tag only apply to the elements within the same parent element that contains the scoped
<style> tag. This containment prevents style bleeding or interference with other sections of the webpage.
Benefits of Scoped CSS:

- Scoped CSS promotes modularity by allowing developers to style specific components without affecting the rest of the page, enhancing code organization and maintainability.
Avoidance of Style Conflicts:
- By confining styles to a particular section, scoped CSS reduces the risk of conflicts that may arise when working with larger or complex web applications.
- With scoped CSS, it becomes easier to understand and manage styles as they are closely tied to the elements they affect, improving code readability.
