I will develop a before/after slider for your portfolio

I make interactive before/after sliders where the divider line is dragged with finger or mouse and gradually reveals the second photo over the first. Over several years I've built dozens of such widgets for repair masters, cosmetologists, and landscape designers — those who need to quickly and clearly show work results without redeveloping for each new project.

Each slider I deliver to the client is a compact independent block, embedded in almost any website, landing page, or page builder. Visitors drag a vertical line left-right or swipe with their finger on phone, and one image smoothly transitions to another. I keep the code light without heavy libraries, so animation doesn't lag even on budget smartphones — and such portfolios are usually viewed from phones, and I test this on real devices.

I separately work on details that affect the impression of the result: I align before and after frames so nothing jumps or shifts when dragging, add captions if needed, and build the layout — from one header slider to an entire project gallery.

What's included in the work:
— adaptive slider supporting touch, mouse, and keyboard
— image optimization so the page doesn't lose speed
— clean code that any developer can later refine
— multiple sliders on one page without conflicts
— basic color and line style tuning to match your style
