1. How do I use UIkit components like grid and cards here?
You can use UIkit’s grid classes together with card components.
<div class="uk-container uk-margin-top">
<div class="uk-child-width-1-2@m uk-grid-match" uk-grid>
<div>
<div class="uk-card uk-card-default uk-card-body">
<h3 class="uk-card-title">Card One</h3>
<p>Responsive UIkit card content.</p>
</div>
</div>
<div>
<div class="uk-card uk-card-primary uk-card-body">
<h3 class="uk-card-title">Card Two</h3>
<p>Another responsive card.</p>
</div>
</div>
</div>
</div>
The uk-child-width-1-2@m class displays two columns on medium and larger screens while allowing the layout to adapt on smaller devices.
2. Do I need to link the UIkit CSS and JS CDN manually in this compiler?
No. The playground is configured with UIkit framework support, so you can use supported UIkit classes and JavaScript components without manually adding CDN links for normal examples.
For example:
<button class="uk-button uk-button-primary">
Primary Button
</button>
<button class="uk-button uk-button-default">
Default Button
</button>
For production websites, you should still install or load the UIkit version required by your actual project.
3. Is this online compiler suitable for testing responsive web layouts?
Yes. UIkit includes responsive grids, width utilities, visibility helpers, containers, and flexible layout classes that make it useful for testing responsive interfaces.
<div class="uk-container">
<div class="uk-grid-small uk-child-width-1-1 uk-child-width-1-3@m" uk-grid>
<div>
<div class="uk-card uk-card-default uk-card-body">
Column 1
</div>
</div>
<div>
<div class="uk-card uk-card-default uk-card-body">
Column 2
</div>
</div>
<div>
<div class="uk-card uk-card-default uk-card-body">
Column 3
</div>
</div>
</div>
</div>
Here, the columns use full width on smaller screens and switch to a three-column layout on medium screens and above.
4. Can I write custom CSS along with UIkit classes?
Yes. You can use UIkit for the base structure and add custom CSS for branding, spacing, colors, or component adjustments.
<div class="uk-container uk-margin-large-top">
<div class="uk-card uk-card-default uk-card-body custom-profile">
<h2 class="uk-card-title">
Developer Profile
</h2>
<p>
UIkit component with additional custom styling.
</p>
<button class="uk-button uk-button-primary">
View Profile
</button>
</div>
</div>
The Online UIkit Compiler / Playground is useful for frontend developers, web designers, and students who want to practice responsive layouts, UIkit components, custom CSS, and lightweight frontend design without setting up a complete local project.
