Resizable containers empower different users to customize a UI to emphasise what they find most important. A basic implementation of this is a split view or split pane, allowing users to enlarge content that is more relevant to them.When you needed to add support for a resizable panel-based layout in HTML. Specifically, this is for HTML Help Builder which is an application that generates HTML-based documentation from class libraries, and databases and that also lets you create help topics manually for full documentation purposes. The generated output for documentation typically has a two-panel layout and I needed to integrate resizing functionality from the old-school frames interface that had been in use before.There are libraries that can implement this feature for you, but creating it yourself gives you full control over the styling and functionality, so you can rapidly tailor it to your project.There are many code snippets available online or on many other blogs and websites, but everyone cannot optimize your blog or website, so you need some optimized code snippets. So now checkout out the code snippet for your blog and website that will give you all features for your desired code. Now grab the ready-to-use code and paste it where you want.CLICK HERE TO SEE DEMOFeatures:Light Weight.Pure JavaScript Code.Cross Browser.No External Files.Fully Customizable.Responsive.How To Create Resizable Split DIVs Using Pure JavaScript?There are a few easy and understandable steps to achieve your desired functionality that we are gonna share below.
