Essential Concepts#

1. Grid System#

<div class="container">
    <div class="row">
        <!-- Equal width columns -->
        <div class="col">Column 1</div>
        <div class="col">Column 2</div>
        <div class="col">Column 3</div>

        <!-- Specific width columns -->
        <div class="col-12 col-md-6 col-lg-4">Responsive Column</div>
    </div>
</div>

2. Responsive Breakpoints#

// Bootstrap breakpoints
$grid-breakpoints: (
    xs: 0,
    sm: 576px,
    md: 768px,
    md: 992px,
    lg: 1200px,
    xl: 1400px
);

// Usage example
<div class="col-12 col-md-6 col-lg-4">
    <!-- Full width on mobile, half on tablet, third on desktop -->
</div>

3. Container Types#

<!-- Fixed-width container -->
<div class="container">
    <!-- Content -->
</div>

<!-- Fluid container (full-width) -->
<div class="container-fluid">
    <!-- Content -->
</div>

<!-- Responsive containers -->
<div class="container-sm">
<div class="container-md">
<div class="container-lg">
<div class="container-xl">
