The no-JS constraint was the whole point and I almost glossed over it.
Start by clarifying the requirements and constraints, then outline a semantic HTML structure using a form with an input and button. Explain your CSS approach for layout, spacing, and interactive states, emphasizing cross-browser compatibility and accessibility. Finally, discuss trade-offs and potential enhancements without JavaScript.
Pro tip: Use CSS custom properties for colors and spacing to make the component easily themeable and maintainable, and mention that you'd test with keyboard navigation and screen readers to ensure accessibility.
Ask about expected behavior, such as whether the form should submit to a server or if it's purely presentational, and any design constraints like responsiveness or theming.
Use a <form> element with an <input type='search'> or <input type='text'> and a <button type='submit'>. Include appropriate labels and ARIA attributes for accessibility.
Use flexbox or grid to align the input and button, apply padding and margins for spacing, and ensure the component is responsive with relative units.
Define :hover, :focus, and :active styles for both the input and button, using outlines or box-shadows for focus visibility. Ensure these states are consistent across browsers.
Use vendor prefixes where necessary, test in multiple browsers, and consider using a CSS reset or normalize.css to ensure consistent rendering.
