Bootstrap PPT Part - 2

Glyphicons
• Bootstrap provides 250 to 260 glyphicons from the Glyphicons Halflings set.
• Glyphicons can be used in text, buttons, toolbars, navigation, forms, etc.
Example:
Glyphicon Syntax:
<span class="glyphicon glyphicon-name"></span>

Dropdowns
• A dropdown menu is a toggleable menu that allows the user to choose one value from a
predefined list.
• Example:
• The .dropdown class indicates a dropdown menu.
• To open the dropdown menu, use a button or a link with a class of .dropdown-toggle and
the data-toggle="dropdown" attribute.
• The .caret class creates a caret arrow icon (), which indicates that the button is a
dropdown.
• Add the .dropdown-menu class to a <ul> element to actually build the dropdown menu.

Dropup
• The dropdown menu to expand upwards instead of downwards, change the <div>
element with class="dropdown" to “dropup”.
• Example:
• Syntax :<div class="dropup">…….</div>
Divider:
• Add a divider to separate series of links in a dropdown menu.
• Syntax:<ul class="dropdown-menu" >
...
<li role="separator" class="divider"> </li>
...
</ul>

Button Groups
 Bootstrap allows you to group a series of buttons together (on a single line).
 Use a <div> element with class .btn-group to create a button group.
 Syntax :
Button toolbar:
 Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex
components.
Example:<div class="btn-toolbar" role="toolbar" aria-label="...">
<div class="btn-group" role="group" aria-label="...">
</div> <div class="btn-group" role="group" aria-label="...">.
</div> <div class="btn-group" role="group" aria-label="...">
</div> </div>

Sizing:
Instead of applying button sizing classes to every button in a group, just add .btn-
group-* to each .btn-group, including when nesting multiple groups.
Example:
<div class="btn-group btn-group-lg" role="group" aria-label="...">
</div><div class="btn-group" role="group" aria-label="..."></div>
<div class="btn-group btn-group-sm" role="group" aria-label="..."></div>
<div class="btn-group btn-group-xs" role="group" aria-label="..."></div>

Nesting:
 Place a .btn-group within another .btn-group when you want
dropdown menus mixed with a series of buttons.
Example:
Vertical variation:
 Make a set of buttons appear vertically stacked rather than
horizontally.

Justified button groups:
With <a> elements: Wrap a series of .btns in .btn-group.btn-group
justified.
With <button> elements: Justified button groups with
<button> elements, must wrap each button in a button group.

Button dropdowns:
 Use any button to trigger a dropdown menu by placing it within a .btn-
group and providing the proper menu markup.
Single button dropdowns:
 Turn a button into a dropdown toggle with some markup changes.
Split button dropdowns:
 create split button dropdowns with the same markup changes, only with a
separate button.

Sizing:
 Button dropdowns work with buttons of all sizes.
Dropup variation:
 Trigger dropdown menus above elements by adding .dropup to the
parent.

Input groups:
 Extend form controls by adding text or buttons before, after, or on both sides of any text-based
<input>. Use .input-group with an .input-group-addon or .input-group-btn to prepend or append
elements to a single .form-control.
 Place one add-on or button on either side of an input. You may also place one on both sides of
an input.

Sizing:
 Add the relative form sizing classes to the .input-group itself and contents
within will automatically resize
 No need for repeating the form control size classes on each element.

Checkboxes and radio addons:
 Checkbox or radio option will be placed within an input group's addon
instead of text.
Button addons:
 Buttons in input groups are a bit different and require one extra level of
nesting. Instead of .input-group-addon, you'll need to use .input-group
btn to wrap the buttons.

Buttons with dropdowns:
It shows the buttons with dropdowns.
Segmented buttons:
The input text can contain text, button and a dropdown.

Multiple buttons:
While you can only have one add-on per side, you can have multiple buttons inside
a single .input-group-btn.

Navs
 Bootstrap provides an easy and quick way to create basic nav
components like tabs and pills which are very flexible and elegant.
 All the Bootstrap's nav components—tabs and pills—share the same base
markup and styles through the base .nav class.
Tabs
Tabs are created with <ul class="nav nav-tabs">
Also mark the current page with <li class="active">.

Pills:
 Pills are created with <ul class="nav nav-pills">. Also mark the current page with
<li class="active">
 Pills are also vertically stackable. Just add .nav.stacked.

Justified:
 Easily make tabs or pills equal widths of their parent at screens wider than 768px with .nav-
justified. On smaller screens, the nav links are stacked.
Disabled links:
For any nav component (tabs or pills), add .disabled for gray links and no hover effects.

Using dropdowns:
Add dropdown menus for tabs and pills by using this syntax
classes:
Tabs with dropdowns:

Modal
The Modal plugin is a dialog box/popup window that is displayed on top of the current page.
Syntax:

Example Explanation
The "Trigger" part:
To trigger the modal window, you need to use a button or a link.
Then include the two data-* attributes:
data-toggle="modal" opens the modal window
data-target="#myModal" points to the id of the modal
The "Modal" part:
The parent <div> of the modal must have an ID that is the same as the value of the data-target attribute used to trigger the modal
("myModal").
The .modal class identifies the content of <div> as a modal and brings focus to it.
The .fade class adds a transition effect which fades the modal in and out. Remove this class if you do not want this effect.
The attribute role="dialog" improves accessibility for people using screen readers.
The .modal-dialog class sets the proper width and margin of the modal.
The "Modal content" part:
The <div> with class="modal-content" styles the modal (border, background-color, etc.). Inside this <div>, add the modal's header, body, and
footer.
The .modal-header class is used to define the style for the header of the modal. The <button> inside the header has a data-dismiss="modal"
attribute which closes the modal if you click on it. The .close class styles the close button, and the .modal-title class styles the header with a
proper line-height.
The .modal-body class is used to define the style for the body of the modal. Add any HTML markup here; paragraphs, images, videos, etc.
The .modal-footer class is used to define the style for the footer of the modal. Note that this area is right aligned by default.

Model size
• Change the size of the modal by adding the .modal-sm class for small
modals or .modal-lg class for large modals.
• Add the size class to the <div> element with class .modal-dialog.
Small Modal:
<div class="modal-dialog modal-sm">
Large Modal:
<div class="modal-dialog modal-lg">

Scrollspy
The Scrollspy plugin is used to automatically update links in a navigation list
based on scroll position.
Example:

Syntax:

<body data-spy="scroll" data-target=".navbar" data-offset="50">

<nav class="navbar navbar-inverse navbar-fixed-top">
...
<ul class="nav navbar-nav">
<li><a href="#section1">Section 1</a></li>
...
</nav>

<div id="section1">
<h1>Section 1</h1>
<p>Try to scroll this page and look at the navigation bar while scrolling!</p>
</div>
...
</body>

Example Explanation:
• Add data-spy="scroll" to the element that should be used as the
scrollable area (often this is the <body> element).
• Then add the data-target attribute with a value of the id or the class
name of the navigation bar (.navbar). This is to make sure that the
navbar is connected with the scrollable area.
• Note that scrollable elements must match the ID of the links inside the
navbar's list items (<div id="section1"> matches <a href="#section1">).
• The optional data-offset attribute specifies the number of pixels to
offset from top when calculating the position of scroll. This is useful
when you feel that the links inside the navbar changes the active state
too soon or too early when jumping to the scrollable elements. Default
is 10 pixels.

Carousel
The Carousel plugin is a component for cycling through elements, like a
carousel (slideshow).
<div id="myCarousel" class="carousel slide" data-ride="carousel">

<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0" class="active"></li>
<li data-target="#myCarousel" data-slide-to="1"></li>
</ol>

<div class="carousel-inner" role="listbox">
<div class="item active">
<img src="img_chania.jpg" alt="Chania">
</div>
<div class="item">
<img src="img_chania2.jpg" alt="Chania">
</div>
<div class="item">
<img src="img_flower.jpg" alt="Flower">
</div>
<div class="item">
<img src="img_flower2.jpg" alt="Flower">
</div>
</div>

 
<a class="left carousel-control" href="#myCarousel" role="button" data-
slide="prev">
<span class="glyphicon glyphicon-chevron-left" aria-
hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#myCarousel" role="button" data-
slide="next">
<span class="glyphicon glyphicon-chevron-right" aria-
hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>

Affix
 The Affix plugin allows an element to become affixed (locked) to an area on the page.
 Navigation menus or social icon buttons, to make them "stick" at a specific area while scrolling up
and down the page.
 The plugin toggles this behavior on and off (changes the value of CSS position from static to
fixed), depending on scroll position.
