No, you shouldn&#39;t.

A modified version of normalize.css [is already included][1] in Bootstrap 2.3.2. [Here][2] it is.

**UPDATE:** [the docs][3] makes this even more explicit, and now they use the original code, not their fork.

**UPDATE: (Bootstrap 4)**

&gt; For improved cross-browser rendering, we use [Reboot][4] to correct
&gt; inconsistencies across browsers and devices while providing slightly
&gt; more opinionated resets to common HTML elements.

this is my checkbox

**HTML**

    &lt;label class=&quot;checkbox&quot;&gt;
        &lt;input id=&quot;eu_want_team&quot; name=&quot;eu_want_team&quot; type=&quot;checkbox&quot;&gt;
    &lt;/label&gt;

**JQuery**

    var eu_want_team = $(&#39;#eu_want_team&#39;).val();
    alert(eu_want_team);

Its always displaying ON, is it checked or not. Whats the problem with it?



Checkbox value is always &#39;on&#39;

This is a follow up question to a previously answered post: https://stackoverflow.com/questions/18258982/is-there-a-command-line-utility-for-validating-sqlite-databases-in-linux#18259166

If a database is producing the following error:

    $ sqlite3 mydata.db &quot;PRAGMA integrity_check&quot;
    Error: database disk image is malformed

Is there any cleanup processing that can be done to recover the database to a usable state? Even at the potential loss of some corrupt records?

Thanks

How to recover a corrupt SQLite3 database?

I can&#39;t figure out if I need to add the [normalize.css][1] stylesheet in my bootstrap project. I&#39;m using the latest version of bootstrap, v2.3.2.

Should I use normalize.css in my Bootstrap project?

<p>I can't figure out if I need to add the <a href="http://necolas.github.io/normalize.css/" target="_blank" rel="noopener noreferrer">normalize.css</a> stylesheet in my bootstrap project. I'm using the latest version of bootstrap, v2.3.2.</p>


Using the core example taken from the Bootstrap 3 Javascript [examples page for Collapse][1],
 I have been able to show the state of collapse using chevron icons.

I have this working using:

&lt;!-- language: lang-js --&gt;
        
    $(&#39;#accordion .accordion-toggle&#39;).click(function (e) {
        var chevState = $(e.target).siblings(&quot;i.indicator&quot;).toggleClass(&#39;glyphicon-chevron-down glyphicon-chevron-up&#39;);
        $(&quot;i.indicator&quot;).not(chevState).removeClass(&quot;glyphicon-chevron-down&quot;).addClass(&quot;glyphicon-chevron-up&quot;);
    });

This works (not fully tested in all browsers), but I&#39;m wondering if there&#39;s a more elegant solution to this?

Ideally I&#39;d like to use the core function, but I&#39;m not sure how to achieve the same results with it.

&lt;!-- language: lang-js --&gt;

    $(&#39;#accordion&#39;).on(&#39;hidden.bs.collapse&#39;, function () {
        //do something...
    })


Here&#39;s a working version in **[jsfiddle][2]**.

Bootstrap 3 Collapse show state with Chevron icon

I just started a new project with the new Twitter Bootstrap release : bootstrap 3. 
I can&#39;t make the Modal work in the remote mode. I just want that when I click on a link it shows the modal with the content of the remote url.
It works but the modal layout is completely destroyed.

Here is a link to a jsfiddle : http://jsfiddle.net/NUCgp/5/

The code :

    &lt;a data-toggle=&quot;modal&quot; href=&quot;http://fiddle.jshell.net/Sherbrow/bHmRB/0/show/&quot; data-target=&quot;#myModal&quot;&gt;Click me !&lt;/a&gt;
    
    &lt;!-- Modal --&gt;
    &lt;div class=&quot;modal fade&quot; id=&quot;myModal&quot; tabindex=&quot;-1&quot; role=&quot;dialog&quot; aria-labelledby=&quot;myModalLabel&quot; aria-hidden=&quot;true&quot;&gt;
        &lt;div class=&quot;modal-dialog&quot;&gt;
            &lt;div class=&quot;modal-content&quot;&gt;
                &lt;div class=&quot;modal-header&quot;&gt;
                    &lt;button type=&quot;button&quot; class=&quot;close&quot; data-dismiss=&quot;modal&quot; aria-hidden=&quot;true&quot;&gt;&amp;times;&lt;/button&gt;
                     &lt;h4 class=&quot;modal-title&quot;&gt;Modal title&lt;/h4&gt;
    
                &lt;/div&gt;
                &lt;div class=&quot;modal-body&quot;&gt;&lt;div class=&quot;te&quot;&gt;&lt;/div&gt;&lt;/div&gt;
                &lt;div class=&quot;modal-footer&quot;&gt;
                    &lt;button type=&quot;button&quot; class=&quot;btn btn-default&quot; data-dismiss=&quot;modal&quot;&gt;Close&lt;/button&gt;
                    &lt;button type=&quot;button&quot; class=&quot;btn btn-primary&quot;&gt;Save changes&lt;/button&gt;
                &lt;/div&gt;
            &lt;/div&gt;
            &lt;!-- /.modal-content --&gt;
        &lt;/div&gt;
        &lt;!-- /.modal-dialog --&gt;
    &lt;/div&gt;
    &lt;!-- /.modal --&gt;

Can anyone make this simple example work ?

Bootstrap 3 with remote Modal

here is sample link: http://bootply.com/76369

this is html i use.

    &lt;div class=&quot;row&quot;&gt;
      &lt;div class=&quot;col-md-6&quot;&gt;.col-md-6&lt;/div&gt;
      &lt;div class=&quot;col-md-6&quot;&gt;.col-md-6&lt;/div&gt;
    &lt;/div&gt;

bootstrap 3 has no container-fluid and row-fluid. 

i cannot wrap it with .container class because it will become fixed layout.

**how to make it fluid** (full page width) **layout?** (**without horizontal scrollbar**)

with these markup. when you view in the result the **x-scroll** bar is visible so you can scroll to left and right that it should not.

Already got answer and Bootstrap already released the fix since 3.1.0

How to make bootstrap 3 fluid layout without horizontal scrollbar

I am new to Bootstrap and I&#39;m having trouble getting the popover and tooltip features to work. I had no problem with the drop downs and models but I seem to be missing something for the popover and tooltips. 

I am getting tooltips to show up but they are not styled and located like the bootstrap examples. And the popover is not working at all.

Please take a look and let me know what I am missing.

Bootstrap 3.0 Popovers and tooltips

This is a two part question:

 1. How can you position the modal vertically in the center when you don&#39;t know the exact height of the modal?

 2. Is it possible to have the modal centered and have overflow:auto in the modal-body, but only if the modal exceeds the screen height?

I have tried using this:

    .modal-dialog {
      height: 80% !important;
      padding-top:10%;
    }

    .modal-content {
      height: 100% !important;
      overflow:visible;
    }

    .modal-body {
      height: 80%;
      overflow: auto;
    }

This gives me the result I need when the content is much larger than vertical screen size, but for small modal contents it&#39;s pretty much unusable.

Bootstrap 3 modal vertical position center

I have a dataframe in pandas where each column has different value range. For example:

df:

    A     B   C
    1000  10  0.5
    765   5   0.35
    800   7   0.09


Any idea how I can normalize the columns of this dataframe where each value is between 0 and 1?

My desired output is:

    A     B    C
    1     1    1
    0.765 0.5  0.7
    0.8   0.7  0.18(which is 0.09/0.5)


Normalize columns of pandas data frame

I have a numpy array where each cell of a specific row represents a value for a feature. I store all of them in an 100*4 matrix.

    A     B   C
    1000  10  0.5
    765   5   0.35
    800   7   0.09  

Any idea how I can normalize rows of this numpy.array where each value is between 0 and 1?

My desired output is:

    A     B    C
    1     1    1
    0.765 0.5  0.7
    0.8   0.7  0.18(which is 0.09/0.5)

Thanks in advance :)
