Understanding the Grid System

Custom Theming with Sass
Create custom Bootstrap themes using Sass:
// Custom variables $primary: #007bff; $secondary: #6c757d; $success: #28a745; $info: #17a2b8; $warning: #ffc107; $danger: #dc3545; $light: #f8f9fa; $dark: #343a40; // Custom font $font-family-sans-serif: 'Inter', -apple-system, BlinkMacSystemFont, sans-serif; // Custom spacing $spacer: 1rem; $spacers: ( 0: 0, 1: $spacer * .25, 2: $spacer * .5, 3: $spacer, 4: $spacer * 1.5, 5: $spacer * 3, 6: $spacer * 4, 7: $spacer * 5, ); // Custom border radius $border-radius: .375rem; $border-radius-sm: .25rem; $border-radius-lg: .5rem; // Import Bootstrap @import "bootstrap/scss/bootstrap"; // Custom styles .hero-section { background: linear-gradient(135deg, $primary 0%, darken($primary, 15%) 100%); } .feature-icon { transition: transform 0.3s ease; &:hover { transform: scale(1.1); } } .card { transition: transform 0.3s ease, box-shadow 0.3s ease; &:hover { transform: translateY(-5px); box-shadow: 0 10px 25px rgba(0, 0, 0, 0.1) !important; } } .btn { border-radius: $border-radius; font-weight: 500; transition: all 0.3s ease; &:hover { transform: translateY(-2px); } }
Responsive Utilities
Use Bootstrap's responsive utilities effectively:
<!-- Responsive text alignment --> <p class="text-start text-md-center text-lg-end"> This text aligns differently on different screen sizes. </p> <!-- Responsive display --> <div class="d-none d-md-block"> This content is hidden on mobile but visible on medium screens and up. </div> <div class="d-block d-md-none"> This content is visible on mobile but hidden on medium screens and up. </div> <!-- Responsive spacing --> <div class="p-3 p-md-4 p-lg-5"> This element has different padding on different screen sizes. </div> <!-- Responsive grid --> <div class="row"> <div class="col-12 col-sm-6 col-md-4 col-lg-3 col-xl-2"> <div class="card"> <div class="card-body"> <h6>Responsive Card</h6> <p class="small">This card adapts to screen size.</p> </div> </div> </div> </div>
