What Brutalism does
The Brutalism skill provides a comprehensive guide for developers and designers looking to embrace the raw aesthetic of Brutalism in their web and app projects. This skill is ideal for those who want to create designs that intentionally reject the polished and refined look typical of modern interfaces. By using unstyled components and exposing structural elements, this approach celebrates default browser styling and creates a unique visual experience.
Core principles of Brutalism include the use of unstyled components, exposed structure, and an anti-aesthetic approach that may feel awkward or unfinished. The skill encourages developers to utilize stark boundaries, high-contrast colors, and basic typography choices like Courier New or Times New Roman. This results in a design that is not only eye-catching but also distinctively different from conventional styles.
The skill provides practical implementation examples for various platforms, including standard HTML/CSS, SwiftUI, Flutter, and React Native. Each implementation emphasizes the use of default styling, avoiding frameworks or libraries that introduce polished components. By following the provided CSS and code snippets, users can create interfaces that align with the Brutalist aesthetic, featuring visible borders, stark color contrasts, and a focus on raw materials.
Brutalism is particularly suited for projects where a unique visual identity is desired, or when the goal is to challenge standard design conventions. It is perfect for developers and designers who appreciate a more experimental approach to UI design and want to create something that stands out from the crowd.

When to Use
Use this sub-style when the user's request matches the aesthetic described above. This is a child reference of the design-it skill and is not meant to be triggered directly.
Core Principles
- Unstyled Components: Default browser styling for buttons, inputs, and links is celebrated.
- Exposed Structure: Grid lines, tables with visible borders, and stark boundaries are used instead of whitespace to separate content.
- Anti-Aesthetic: Intentional awkwardness. Elements might slightly overlap in a way that feels broken, or use system default fonts.
Visual DNA
- Colors: High contrast, often clashing. Pure
#0000FFblue for links,#FF0000red for accents, on stark white or#C0C0C0grey backgrounds. Industrial Chic palette fits best. - Typography: Courier New, Times New Roman, Comic Sans, or default sans-serifs. No web fonts.
- Visuals: Dithered images, pixelated graphics, or heavily compressed jpegs.
Web Implementation
- Use standard HTML tags without overriding their default appearance whenever possible.
- CSS Example:
body {
background-color: #ffffff;
color: #000000;
font-family: monospace;
}
/* Expose the structure */
.brutalist-container {
border: 1px solid #000;
padding: 10px;
}
.brutalist-section {
border-bottom: 2px dashed #000;
margin-bottom: 20px;
padding-bottom: 20px;
}
/* Default-looking button but massive */
.brutalist-btn {
background-color: #c0c0c0;
border: 2px outset #ffffff;
border-right-color: #000000;
border-bottom-color: #000000;
color: #000000;
font-family: sans-serif;
font-size: 24px;
padding: 10px 20px;
cursor: pointer;
}
.brutalist-btn:active {
border-style: inset;
}
/* System link blue */
a {
color: #0000FF;
text-decoration: underline;
}
App Implementation
SwiftUI
struct BrutalistView: View {
var body: some View {
VStack(alignment: .leading, spacing: 0) {
Text("BRUTALISM")
.font(.custom("Courier New", size: 32))
.foregroundColor(.black)
.padding(10)
.border(Color.black, width: 2)
Divider().background(Color.black).padding(.vertical, 20)
Button(action: {}) {
Text("CLICK_HERE")
.font(.custom("Courier New", size: 24))
.foregroundColor(.blue)
.underline()
}
.padding(10)
// Raw structural container
VStack(alignment: .leading) {
Text("System Status: RAW").font(.custom("Courier New", size: 14))
}
.padding()
.border(Color.black, width: 1)
}
.padding()
.frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .topLeading)
.background(Color.white)
}
}
- Avoid all native
ButtonStylecomponents. UseTextwith.underline()mapped to system blue. - Use
.border(Color.black, width: 1)instead of backgrounds or shadows. - Force monospace fonts like Courier New or Menlo.
Flutter
class BrutalistScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
// DO NOT use MaterialApp theme or Scaffold if possible,
// or strip them down completely.
return Scaffold(
backgroundColor: Colors.white,
body: SafeArea(
child: Padding(
padding: const EdgeInsets.all(16.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
padding: const EdgeInsets.all(8),
decoration: BoxDecoration(
border: Border.all(color: Colors.black, width: 2),
),
child: const Text(
'BRUTALISM',
style: TextStyle(
fontFamily: 'Courier',
fontSize: 32,
color: Colors.black,
),
),
),
const Padding(
padding: EdgeInsets.symmetric(vertical: 20),
child: Divider(color: Colors.black, thickness: 2),
),
GestureDetector(
onTap: () {},
child: const Text(
'CLICK_HERE',
style: TextStyle(
fontFamily: 'Courier',
fontSize: 24,
color: Colors.blue,
decoration: TextDecoration.underline,
),
),
),
],
),
),
),
);
}
}
- Avoid
ElevatedButton,Card, orAppBar. - Build UI out of raw
Containers withBorder.all(color: Colors.black)andTextwidgets. - Use
TextDecoration.underlineto indicate interactivity.
React Native
const BrutalistScreen = () => {
return (
<View style={{ flex: 1, backgroundColor: '#FFFFFF', padding: 16 }}>
<View style={{
borderWidth: 2,
borderColor: '#000000',
padding: 10,
alignSelf: 'flex-start'
}}>
<Text style={{ fontFamily: 'monospace', fontSize: 32, color: '#000' }}>
BRUTALISM
</Text>
</View>
<View style={{ height: 2, backgroundColor: '#000', marginVertical: 20 }} />
<TouchableOpacity activeOpacity={1}>
<Text style={{
fontFamily: 'monospace',
fontSize: 24,
color: '#0000FF',
textDecorationLine: 'underline'
}}>
CLICK_HERE
</Text>
</TouchableOpacity>
<View style={{
borderWidth: 1,
borderColor: '#000',
padding: 16,
marginTop: 40
}}>
<Text style={{ fontFamily: 'monospace', color: '#000' }}>
System Status: RAW
</Text>
</View>
</View>
);
};
- Strip away all native feel. Do not use
react-native-elementsorreact-native-paper. - Set
activeOpacity={1}onTouchableOpacityso there is no smooth fade — it should just click instantly. - Use pure hex colors:
#FFFFFF,#000000,#0000FF.
Jetpack Compose
@Composable
fun BrutalistScreen() {
Column(
modifier = Modifier
.fillMaxSize()
.background(Color.White)
.padding(16.dp)
) {
Box(
modifier = Modifier
.border(2.dp, Color.Black)
.padding(10.dp)
) {
BasicText(
text = "BRUTALISM",
style = TextStyle(
fontFamily = FontFamily.Monospace,
fontSize = 32.sp,
color = Color.Black
)
)
}
Spacer(Modifier.height(20.dp))
Box(modifier = Modifier.fillMaxWidth().height(2.dp).background(Color.Black))
Spacer(Modifier.height(20.dp))
BasicText(
text = "CLICK_HERE",
modifier = Modifier.clickable { },
style = TextStyle(
fontFamily = FontFamily.Monospace,
fontSize = 24.sp,
color = Color.Blue,
textDecoration = TextDecoration.Underline
)
)
}
}
- Use
BasicTextinstead ofTextto bypass Material theme defaults. - Build structural lines using
Boxwith.background(Color.Black). - Do not use
ButtonorCardor any Material composables. Raw layouts only.
Do's and Don'ts
- DO: Use harsh, high-contrast borders (1px solid black) around everything.
- DON'T: Use border-radius, drop shadows, or smooth transitions. If it animates, it should pop instantly (0s transition).
Limitations
- This is a styling reference and does not replace environment-specific validation, accessibility testing, or expert review.
- Ensure appropriate contrast ratios and responsive behaviors are verified separately.
