Example Slide Menu using Slidebars

I’ve been looking for an easy way to implement a side menu that works with Bootstra’s navbar. Here is a great plugin to use!


To use this, you just need to add in the Slidebar css and javascript file to your page.  You can also use a cdn:



The Javascript

The trick is to disable Bootstrap’s mobile menu click. You can achieve this by removing the attribute, data-toggle=”collapse” from your button. (I just added a ~tilde to the value like this, data-toggle=”~collapse”, so that I can disable it.) At full view, the Bootstrap navbar drop down menus still work. But the mobile menu will slide out a new menu similar to how a mobile app works.


When the view port is small enough, the Bootstrap mobile menu will appear. And when you click on this, your side menu will appear!


I also added a second button to show how I would toggle another side menu.


Here is a live demo.

Static / Sticky Footer

This is the best solution I found so far.


The CSS.

html {
    position: relative;
    min-height: 100%;
body {
    margin: 0 0 100px; /* bottom = footer height */
footer {
    position: absolute;
    left: 0;
    bottom: 0;
    height: 100px;
    width: 100%;

Here is how you would use it.

<!DOCTYPE html>
    <article>Lorem ipsum...</article>

Check if Browser is IE and Which Version of IE with HTML

Check if the browser is using IE8

<!--[if IE 8]> 
	<script src="_ie8.js"></script>

This stylesheet will only display to IE9 or above, along with every other non-IE browser. Notice opening and closing expressions are wrapped in comments.

<!--[if gt IE 8]><!-->
	<script src="_nonIe8.js"></script>

**Make sure the src path reference begins with a slash (/scripts/myscript) and not use the root tilde reference. This (~) doesn’t seem to work within the conditional hthml.

HTML5 shim and Respond.js IE8 support of HTML5 elements and media queries. This is for Bootstrap 3 support.

<!--[if lt IE 9]>
	<script src="~/../Scripts/html5shiv-3.7.0.js"></script>
	<script src="~/../Scripts/respond.min-1.4.2.js"></script>
	<link href="~/../Content/bootstrap-glyphicons.css" rel="stylesheet" />

Styling that has been applied with global CSS Classes can be overridden if you add an ID attribute to the containing span or div.

Some times you need to “push” against an empty div, you can use a div with an empty value like this.

<div style="padding-bottom:50px"></div>

CSS Precedence

Filed under: CSS / Styling — Duy Nguyen @ 1:31 pm

From MSDN:

Precedence of CSS Style Rules:

CSS style rules cascade in the sense that global style rules continue to apply to HTML elements unless local style rules supplant them. In general, local style rules take precedence over general style rules. This means, for example, that a style defined in a STYLE block within a Web page can revise for that one page a Web site style defined in an external CSS style sheet. Similarly, an in-line style defined within a single HTML tag on that page can revise for one line any styles defined for that same element elsewhere.
Portions of global style rules not contradicted by local CSS style rules will continue to apply to HTML elements even after local styles are applied. In the example above, the local CSS styles governing text between <H1> tags replace some of the Web browser’s global style rules for <H1> text (center <H1> text and make it red), but they do not change others (display all <H1> text in a larger font and bolded). Both global and local style rules are applied, in that order, making all the <H1> text on this page display in a larger font and bolded, and centered and red.

Here is a great link about weighing CSS specificity.

You can disable strong name valildation on an assembly using the Strong Name tool that comes with Visual Studio.

Open the Visual Studio Command Prompt. This should be available on Start, All Program Files, Visual Studio 200x, Visual Studio Tools.

At the command prompt:
SN -Vr “c:\location of the assembly\myassembly.dll”

To re-enable verification:

SN -Vu “c:\location of the assembly\myassembly.dll”
