Frontend developers ensure that a website or application is user-friendly, visually appealing, and accessible on multiple devices and platforms - using coding technologies like HTML, CSS, and JavaScript to create visually appealing and functional interfaces. They work closely with designers to ensure that the visual design is accurately implemented and that the end product meets the desired specifications. Considering that a study by Adobe found that 38% of people will stop engaging with a website if the content or layout is unattractive, frontend development has increasingly risen in popularity for decades, with companies prioritizing a strong user interface throughout the development process.
