I think it will be a confluence of:<p>* Flexbox being widely supported (a lot of css is just positioning&#x2F;ordering content)<p>* Standard style libraries doing most needed appearance stuff in HTML.<p>* Most brochure sites being sublimated into Facebook for Business&#x2F;Squarespace&#x2F;Shopify&#x2F;Facebook Messenger or some other chat interface. A &quot;nice-looking&quot; website beyond available templates will be worth less and less.<p>* SaaS continuing to grow and offer hosted solutions for specialized websites&#x2F;web applications. Already seeing this a lot with restaurants.<p>* Available React components continuing to grow - you will be able to develop a heavy front-end application using 90% existing modules. React will be bigger than jQuery because of this and because minor use of jQuery for style reasons will fade along with heavily customized CSS.
