1

HTML/CSS basics

Candidates should have a good understanding of HTML and CSS, including the use of basic HTML tags and properties, as well as knowledge of CSS selectors, properties, and values. This sub-skill is crucial because HTML and CSS are the foundation of front-end web development, and having a solid grasp of these concepts is necessary for building web pages that are visually appealing and functional.

2

JavaScript basics

Candidates should have a good understanding of JavaScript, including variables, data types, operators, loops, and functions.

3

DOM manipulation

Candidates should be able to manipulate the Document Object Model (DOM) using JavaScript to add, remove, and modify HTML elements dynamically. This sub-skill is crucial because the DOM is the interface between HTML/CSS and JavaScript, and being able to manipulate it effectively is necessary for building interactive web pages.

4

Responsive design

Candidates should have a good understanding of responsive design principles and techniques, including the use of media queries and responsive units like ems and rems.

Web accessibility

Candidates should have a good understanding of web accessibility guidelines and techniques, including the use of semantic HTML, ARIA attributes, and other accessibility features. This sub-skill is crucial because web accessibility is essential for ensuring that web pages are accessible to all users, including those with disabilities, and complying with accessibility standards is often a legal requirement for organizations.
