Kraft-Paper Background Grain
MUJI's signature material quality comes from a subtle kraft-paper texture overlaid on the warm cream background. This creates the tactile impression of recycled paper packaging — the brand's most recognizable material.

background-color: #F8F4ED;

}
.muji-surface::after {

Underline-Only Input Field
MUJI's form inputs strip away the conventional bordered rectangle, leaving only a bottom border — an editorial, Japanese-print-inspired approach that treats the input as a line on a page rather than a box.
.muji-input {
width: 100%;
padding: 8px 0;
border: none;
border-bottom: 1px solid #e0d8cc;
background: transparent;
color: #1A1A1A;
font-family: 'Inter', 'Hiragino Sans', sans-serif;
font-size: 0.875rem;
line-height: 1.6;
outline: none;
transition: border-color 200ms ease;
border-radius: 0;
-webkit-appearance: none;
}
.muji-input:focus {
border-bottom-color: #1A1A1A;
}
.muji-input::placeholder {
color: #999999;
}
Regular-Weight Heading
MUJI's anti-display typography technique: headings at regular weight (400) rather than bold, creating a quiet, editorial hierarchy that refuses to shout. The heading distinguishes itself through size and spacing alone, not weight.
.muji-heading {
font-family: 'Inter', 'Hiragino Sans', sans-serif;
font-weight: 400;
color: #1A1A1A;
letter-spacing: 0;
line-height: 1.25;
margin-bottom: 1em;
}
.muji-heading--xl { font-size: 3rem; line-height: 1.1; }
.muji-heading--lg { font-size: 2rem; line-height: 1.15; }
.muji-heading--md { font-size: 1.5rem; }
.muji-heading--sm { font-size: 1.125rem; }
