Usage

Once you have Knopf.css included, you can leverage its functionalities right away. By including it, you gain access to a treasure trove of button styles. However, you might want to customize them to align with your design needs.

Override Default Values

You can easily modify the default button styles by overriding the custom properties:

:root { 
   --knopf-hue: 164; 
   --knopf-saturation: 88%; 
   --knopf-luminosity: 28%; 
}

And apply it to a button:

<button class="knopf">Button</button>

Extend Via Modifier

If you want to create variations, you can define a new class with specific values:

.negative {
   --knopf-hue: 356; 
   --knopf-saturation: 57%; 
   --knopf-luminosity: 51%; 
}

Use it on your button:

<button class="knopf negative">Button</button>

Leverage the Cascade

You can easily extend the base class while keeping the existing properties:

.knopf.knopf { 
   --knopf-raised-height: 6px; 
   border-block-end-color: hsl(var(--knopf-hover-background-color)); 
   border-block-end-width: var(--knopf-raised-height); 
   margin-block-start: calc(var(--knopf-raised-height) * -1); 
}
.knopf.knopf:hover { 
   --knopf-raised-height: 2px; 
   border-block-end-color: hsl(var(--knopf-active-background-color)); 
}

Use it with a button:

<button class="knopf large wide pill">Button</button>

The same logic applies to all built-in modifiers. Feel free to check out the playground and experiment with these properties.

Troubleshooting

If you encounter any issues during installation or usage, here are some troubleshooting tips:

• Ensure that the path to the CSS file is correct if you are hosting it locally.
• Double-check any typos in your class names or HTML structure.
• Clear your browser cache if changes to styles are not appearing as expected.
• If using the CDN, verify you’re accessing the correct URL.
