No doubt every web designer has spent many endless hours mocking up web pages, and as such every designer should have a good set of re-usable and uniform Web UI elements that they can rely upon to save them precious time and spare headaches when they are in the initial stages of a web project.
In this article we have 20 completely free Web UI kits and stencils that are perfect for the initial mockup or wireframe stage of a web design project. Most of the kits are editable and the kits are in either .psd, .ai or .png format, but you will also find some Omnigraffle stencils and some kits in .svg format. So, whatever your preferred format you are bound to find the perfect kit for you.
This free Web UI Set has everything included in the PSD file in well organized in folders, and fully editable using vector layers in Photoshop, from the button shapes, to the gradients, and text. Having every element editable means you can recreate anything you need that is not included in the file, just by using existing items as your base.
