07 : Lets have a navbar!

Previously, we served a template but it was not yet satisfying, All it contained was a one-liner message. In this post, we will have a navbar on our homepage. Don't worry, we have done most of the heavy lifting in the previous post.
Ok, so think, Is navbar specific to each page or it is a common resource? Definitely, a common resource, so, we are going to put the navbar in the base.html file. But just see this code of bootstrap-navbar, it is a huge one and will clutter our base.py file. Navbar · Bootstrap v5.3 (getbootstrap.com). Therefore, I am going to put the navbar code inside the templates > components folder. First, add this line to base.html.     {% include "components/navbar.html" %}

<!doctype html>
<html lang="en">
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    {% block title %}
    {% endblock %}
    <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-9ndCyUaIbzAi2FUVXJi0CjmCapSmO7SnpJef0486qhLnuZ2cdeRhO02iuK6FUUVM" crossorigin="anonymous">
    {% include "components/navbar.html" %}
    {% block content %}
    {% endblock %}

    <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js" integrity="sha384-geWF76RCwLtnZ8qwWowPQNguL3RmwHVBC9FhGdlKrxdiJJigb/j/68SIy3Te4Bkz" crossorigin="anonymous"></script>
    {% block scripts %}
    {% endblock %}

Now we can paste the code for the bootstrap navbar in templates> components > navbar.html.

<nav class="navbar navbar-expand-lg bg-body-tertiary">
    <div class="container-fluid">
      <a class="navbar-brand" href="#">Algoholic</a>
      <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
      <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <ul class="navbar-nav me-auto mb-2 mb-lg-0">
          <li class="nav-item">
            <a class="nav-link active" aria-current="page" href="#">Home</a>
          <li class="nav-item">
            <a class="nav-link" href="#">Link</a>
          <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" role="button" data-bs-toggle="dropdown" aria-expanded="false">
            <ul class="dropdown-menu">
              <li><a class="dropdown-item" href="#">Action</a></li>
              <li><a class="dropdown-item" href="#">Another action</a></li>
              <li><hr class="dropdown-divider"></li>
              <li><a class="dropdown-item" href="#">Something else here</a></li>
          <li class="nav-item">
            <a class="nav-link disabled">Disabled</a>
        <form class="d-flex" role="search">
          <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
          <button class="btn btn-outline-success" type="submit">Search</button>

All done, now refresh localhost:8000 and you should see a navbar.🙃
