For a new developer, create magento theme may seem daunting, but with the right approach and tools, it is doable. It is important to start by studying Magento architecture and theme development, master the main files and theme structure. Use development tools such as CSS preprocessors (such as Sass or Less) to create styles, and responsive design frameworks (such as Bootstrap). Remember to test the theme on different screens and browsers to ensure compatibility.
