Study Notes
Bootstrap Navbar Basics
- The navbar is initiated with the
<nav>element, creating a gray separator line at the top of the page. - To add padding and move navbar items inward from the screen edge, wrap elements in a
<div class="container">, but do not nest the navbar itself within this container.
Brand Link Creation
- The "brand" link is generated using the
<a>tag with the classnavbar-brand, providing a reference back to the homepage.
Adding Navbar Items
- Insert additional navbar items (e.g. "About", "Contact") by creating a
<ul>or<div>(with<ul>being conventional) assigned the classnav navbar-nav. - Use nested
<li>tags within the list to link to the respective sections of the website.
Aligning Elements
- Place elements on the right side of the navbar by adding the class
navbar-rightto the parent element.
Required Languages for Dropdowns
- The dropdown functionality relies on jQuery and Bootstrap's JavaScript, with jQuery loaded first followed by Bootstrap's JS.
Making Elements Collapsible on Mobile
- To enable collapsing elements in mobile views, enclose them in a
<div class="collapse" id="...">, linking it to a hamburger icon. - If the hamburger button is not implemented, the enclosed items will simply disappear.
Implementing the Hamburger Button
- The hamburger button code is sourced from the Bootstrap website and is placed before the brand link within the
headertag. - Ensure that the
idof the hamburger button matches theidin the collapse element for proper functionality.
Thumbnail Creation
- Elements placed within the
<div class="thumbnail">will gain thumbnail attributes, enhancing visual presentation.
Adding Glyphicon
- Incorporate Bootstrap's glyphicon by using respective classes, such as the "camera" icon, which can be used as inline text or image.
Fixing Navbar to the Top
- To prevent the navbar from scrolling with the page, apply the class
navbar-fixed-topto the navbar element.
Adjusting for Navbar Overlap
- To mitigate the navbar overlapping other top elements like a jumbotron, add padding to the body's top margin, typically set to 70px.
Changing Navbar Background Color
- Alter the background color of the navbar by modifying one of its assigned classes in CSS, such as
navbar,navbar-default, ornavbar-fixed-top.
