Web Components
Introduced by Alex Rusell at the Fronteers Conference in 2011, Web Components have since gained traction among web developers to create encapsulated and reusable elements for the web.
They look like that:
As you can see, it's not much different than your standard HTML elements like a div or li. Since web components are built with Javascript, they are executed on the client-side, so when visited in a browser. A custom component could be programmed in any way, depending on its purpose.
For example, the goal could be to create a card component that displays the 'name' attribute once executed:
Components behave like standard HTML elements, so you can target them by using CSS:
That's it, for the most part. Let's dive deeper into how spx is utilizing the power of web components.
Attributes
All settings for spx components are applied using attributes. These are no different to attributes for standard HTML elements.
The above code would output a masonry layout of images that spans four columns, with a gap of 2% between images. The number of columns will reduce to 2 when the screen size is under 1000px and to 1 when under 600px.
Every component has different possible attributes that can be applied. Please head to the individual components to find out more.
CSS variables
Components which are not purely functional can also be styled using CSS variables. The variable names correlate with their attribute counterpart like this:
That would create a gap of 10px between all images of all existing masonry components on the site. If you want to target a specific instance, you could give an ID or class to the component:
While it is technically possible to style the components directly and without CSS variables, it is not recommended. Since all CSS is generated dynamically, random classes are being applied by the CSS-in-JS engine (spx is using Emotion). These classes change depending on the applied attributes. CSS variables are also future-proof in case components will be switched over to use the new Shadow DOM API.
On top of that, some component attributes apply the same value to many different properties for the element to function correctly, making styling without CSS variables not a viable option.
Tokens
Besides variables for all individual components, some general design tokens that affect all components.
Please note that all builder elements use a different system for the font-family and font-size and are thus not altered by the above values.
Responsive design
Creating responsive designs using spx components is straight forward and possible in two different ways. Let's change the font-size of our navigation element for desktop screen sizes.
Using CSS variables is preferred, however, it is also possible to style elements responsively using attributes.
This will have the same result as styling the component with the CSS code from above but instead relies on the ResizeObserver interface to apply the appropriate values. Of course, it is possible to create various breakpoints and add multiple attributes.
Helper functions
While many of the components will work without WordPress, the true, time-saving power of spx comes from using it in conjunction with the provided PHP helper functions. At the moment, helper functions exist for the masonry and navigation component. The navigation component only works using the helper function.
This will automatically create a masonry layout from the ACF gallery!
Slots
Some components have certain slots that can be filled with custom markup. For example, the accordion can be filled with custom slots for the header and content.
Events
Javascript events are being emitted by a couple of components. You can attach an event listener to those just like you normally would.
Methods
Components might expose public methods in Javascript:
The above code would start the animation of the typewriter component. Methods come in handy when trying to interact with other libraries and functions.
Oxygen
Before version 2.0, components were integrated inside of Oxygen as separate elements.
2.0 is changing that behaviour. Instead of individual elements, there now is a master element, which can become any of the core components. This has various advantages for the development team behind spx, since it isn't necessary to implement every component and property again.
Instead, the wrapper now correlates with the core JavaScript components, meaning that every new element and property is immediately available to be used inside Oxygen. Settings can be applied using the "Attributes" text box just like outside of Oxygen. The single components are still available in 2.0, but will be removed with version 3.0. It is advised to use the wrapper element from now on.
Of course, it is still possible to use spx elements inside code blocks.

Introduction
A new feature of version 2.0 is the page builder. It is a collection of components to create responsive, full-page layouts. All of the following elements are part of an evolving system that is supposed to ease the way modern sites are being built.
They are meant to be used together and in many cases are dependant on each other. This is not the case with the core component suite, as they are built (and will continue to be built) as standalone, boxed-off elements. However, this doesn't mean that the core components can't be used with the new building system.
Keep in mind that sections, pages, and the container component and related documentation are in beta, so changes to properties and elements will happen without warning. If you want to see how they work under the hood, check out the source code of the homepage.
Container
The container element is a special component, as it isn't outputting any visible markup. Rather, it's purpose is to provide global styles for section and page components. It does not affect single components and won't ever will.
