How can you ensure cross-browser compatibility in a Liferay theme?

Ensuring cross-browser compatibility in a Liferay theme is best achieved by using CSS resets and frameworks like Bootstrap. CSS resets help standardize the styling across different browsers, as each browser has its own default styles that can vary widely. A CSS reset eliminates these inconsistencies, providing a clean slate for development.

Additionally, Bootstrap is a powerful front-end framework that includes a grid system, pre-defined styles, and common UI components designed to work on various browsers. Using such frameworks helps avoid browser-specific issues that can arise from custom CSS or JavaScript. This combination of CSS resets and responsive frameworks is a proven strategy for achieving a consistent look and feel across different environments.

Testing in only one browser, like Chrome, does not guarantee that the theme will render correctly across other major browsers like Firefox, Safari, or Edge. Limiting JavaScript might help with performance but does not inherently address browser compatibility. Moreover, avoiding custom styling could lead to a lack of uniqueness in design and does not ensure compatibility either; it is often necessary to use some custom styles while ensuring they are well-tested across platforms.
