RSD

Features that make the difference


Allowing you to make design and layout changes wherever needed, breakpoints are truly the secret weapon of responsive design. And with this revolutionary app, they are a cinch to create and manage.

Breakpoints

Use the handy viewport slider to inspect your creation at every possible display width. Anytime something doesn’t quite look its best, drop in a mighty breakpoint to optimize the layout or design.

Slider

Design with Flexbox


Flexbox is fantastic! Align, stack, or reorder elements with the flick of a button. It’s a great instrument that should be part of any responsive design toolkit. To learn more and play with real design examples get our free interactive flexbox guide.

Custom Layouts
With great powers come…great themes!

Even our own designers are still discovering new design possibilities. The themes include text snippets that describe how the design & effects have been created. You can use them to learn, be inspired, or to jumpstart your very own creations. Hop over to our scroll-portfolio theme to marvel at the tricks Responsive Site Designer has to offer.

A design workflow you'll love


Specify the default styles for each element. Then use your own classes to create design variations. Change the properties across the site for every element type, class, or ID with a single edit.

What about variations of a variation? The multi-class system has your back, resulting in design creativity and productivity you can’t experience elsewhere.

Custom Classes

Live Design — Clean Code


Working directly in the browser not only creates the unique live design experience, it also allows the code to be semantic and clean. No (confusing) code generation is needed, the CSS3 is written directly to a real stylesheet, resulting in clean and easy to interpret rules.

The inserted HTML elements are standards based. Tags can be switched with two simple clicks to use semantic HTML5 elements like <nav> and <header>, resulting in well marked-up pages and conveying meaning to search engines.

Clean CSS Semantic HTML

Unprecedented design control


The intuitive controls give access to all the design power CSS has to offer. Without tedious code editing, creating and experimenting comes naturally. Select, click, point, pick and scroll to create websites and pages that are out of this world.

The proof? Hear what our customers are saying and marvel at their masterpieces.

Design Control

Design for wide screens on a laptop


Zoom out to view more. See what the page will look like on monitors that are much wider than the screen you’re working from.

You can also get a better feeling for the page flow by viewing more of the height of the page at the same time — sweet!

Zoom Function

Seeing is Believing


Yup, you can build a custom, responsive design in under 30 minutes! Proven and explained in 8 short videos, we show you how to create the device-agnostic theme below. Anyone can do it. It only takes 80% RSD — 20% skill. Come check it out!

From paper sketches to the production server


Skip static Photoshop or vector design apps. Create directly in the browser with real HTML elements and adaptive grids. Use the full power of CSS3 with intuitive tools.

Design for all devices using easy to manage—custom—media queries. Seeing and feeling the site develop in a production environment (the browser!) is the way of the modern web.

Save a planet — use <picture>


On mobile devices and phone networks, images are often the main bottleneck when it comes to website performance. With the <picture> element, mobile users can be served with optimized or smaller versions of an image.

This greatly improves the user experience and saves costly bandwidth fees. Yup, it's a double win!

Responsive Images

Custom layouts that fit any device


Add rows and content containers with just a simple click. Toggle column spans at custom breakpoints to create tailored layouts for smaller screens. Or create tailored tablet, laptop, desktop and everything in between layouts if you design mobile-first.

You can even use subgrids and container nesting for more ultra-precise layout control. Stretch rows, stop floats, change display properties, constrain heights...this app has it all!

Custom Layouts

Integrated Web Inspector


The web inspector has been an indispensable tool for front end developers for years, and we made it available right within Responsive Site Designer. Use the inspector to view or change (drag-n-drop) an element's position in the DOM tree. Or hover the tree to see each element’s outline.

The applied CSS is visible in the lower pane, making it easy to understand what is happening at each breakpoint. Want to edit the code directly? So do we! (So it will probably happen...soon.)

RSD Inspector

Transitions and effects


Use CSS3 properties such as translate, rotate and skew to create powerful visual effects. On any element and without graphics editor.

Transitions smoothen the value changes defined on different states. Grab the attention and impress visitors when hovering images or pressing buttons. Move it, move it, you gotta move it!

RSD is such a time saver. Easily read all my svg files, queries easily manageable and more importantly affordable. Made my new portfolio with it.
