Yes, an element can have one ID (which must be unique!) and multiple classes at the same time. To have multiple classes, use a space between them, here&#39;s an example:

    &lt;div id=&quot;myID&quot; class=&quot;class1 class2 class3&quot;&gt;Content&lt;/div&gt;

I would like to add that if you add both ID and a class that contradict each other, the ID will have higher priority.

For example:

CSS:
    
    .par_color{
        color:red;
    }

    #par_color{
        color:blue;
    }
HTML:

    &lt;section id=&quot;par_color&quot; class=&quot;par_color&quot;&gt;Some txt&lt;/section&gt;

Some txt string will be shown in blue and not in red.

Yes. Self explanatory.

Additionally, it&#39;s common to have more than one class IE - 

    &lt;div class=&quot;oneClass andAnother&quot;&gt;&lt;/div&gt;

but only one ID per element, and each ID should only be used once per HTML page.

Yes.

    &lt;div id=&quot;main&quot; class=&quot;rounded&quot;&gt;
    &lt;/div&gt;

In short, yes. Usually the class would be for styling and the id to allow direct manipulation by scripts.

yes you can add id and class as well as a class and a id 

for a class and a id`&lt;h1 id=&quot;orange-text&quot; class=&quot;pink-text blue-text&quot;&gt;Hello World!&lt;/h1&gt;`
***for two classes***
`&lt;h1 class=&quot;orange-text&quot; class=&quot;pink-text blue-text&quot;&gt;Hello World!&lt;/h1&gt; `





Yes, you can. But note that Id&#39;s must be unique within your html file, while classes can be used in multiples elements.

    &lt;div class=&quot;examples&quot; id=&quot;example1&quot;&gt;text example&lt;/div&gt;

How to get response as json format(application/json) in yii?

Can an element have both an id and a class?

I&#39;m working on a mobile phone web app and I have several text fields that could benefit from `&lt;input type=&quot;tel&quot;/&gt;`. iPhones will adjust the keyboard for the user, but I&#39;m worried about breaking backwards compatibility. What I&#39;m hoping is that browsers/phone that support this can assist the user and other browser will fall back to a standard text field? Is this an acceptable practice? Does it even work?

Is it okay to use &lt;input type=&quot;tel&quot;/&gt; now?

How can I show HTML snippets on a webpage without needing to replace each `&lt;` with `&amp;lt;` and `&gt;` with `&amp;gt;`?

In other words, is there a tag for *don&#39;t render HTML until you hit the closing tag*?

How to display raw HTML code on an HTML page

The label tag doesn&#39;t have the property &#39;width&#39;, so how should I control the width of a label tag?

How can I control the width of a label tag?

I have a form. Outside that form, I have a button. A simple button, like this:

    &lt;button&gt;My Button&lt;/button&gt;

Nevertheless, when I click it, it submits the form. Here&#39;s the code:

    &lt;form id=&quot;myform&quot;&gt;
        &lt;input /&gt;
    &lt;/form&gt;
    &lt;button&gt;My Button&lt;/button&gt;

All this button should do is some JavaScript. But even when it looks just like in the code above, it submits the form. When I change the tag button to span, it works perfectly. But unfortunately, it needs to be a button. Is there any way to block that button from submitting the form? Like e. g.

    &lt;button onclick=&quot;document.getElementById(&#39;myform&#39;).doNotSubmit();&quot;&gt;My Button&lt;/button&gt;

HTML button to NOT submit form

*Mary had a little form, and its fields where labeled just so.  
Whenever an error crept in, confusion it would sow.*

I&#39;ve got a label for each input field... pretty standard affair.
After validating the form, I&#39;m displaying a helpful little paragraph at the top of the form detailing what information is missing or incorrect.

Can I have two labels for the same input field? One in the form proper, and one in the validation reminder text? Is there any reason I shouldn&#39;t do this?

          p.second {color:green}
        &lt;/style&gt;

        &lt;p class=&quot;first&quot;&gt;Hello World&lt;/p&gt;
        &lt;p class=&quot;second&quot;&gt;Hello World&lt;/p&gt;

        &lt;style type=&quot;text/css&quot;&gt;
          p.first {color:green}
          p.second {color:blue}
        &lt;/style&gt;

        &lt;p class=&quot;first&quot;&gt;Hello World&lt;/p&gt;
        &lt;p class=&quot;second&quot;&gt;Hello World&lt;/p&gt;
      &lt;/body&gt;
    &lt;/html&gt;


How is a browser supposed to render css which is non contiguous? Is it supposed to generate some data structure using all the css styles on a page and use that for rendering?

Or does it render using style information in the order it sees?


Using &lt;style&gt; tags in the &lt;body&gt; with other HTML

I am trying to centre the link with the image, but can&#39;t seem to move the content vertically in any way.

    &lt;a href=&quot;#&quot; class=&quot;pdf&quot;&gt;File Name&lt;/a&gt;

Vertically aligning CSS :before and :after content

&gt;\- A Reuters reporter in Surkhrod district in Nangarhar province, where villagers said the raids took place, said Afghan police fired at the crowd after some of them started throwing stones at local government buildings.

In the above paragraph, I would like to use CSS to make all lines after the first line to automatically indent some space so that each line stays right after the - in the first line.

It&#39;s similar to a list item with list position set to outside, but I don&#39;t want to use a list.

What is the simplest way you can think of to achieve this effect? Less extra html markups will be better.

Text indent after the first line in a paragraph

I have a popup that displays some results, and I want a scroll bar to be display since the results are being cutt off (and I don&#39;t want the popup to be too long).



How do you add a scroll bar to a div?

I want to create a dynamic object (inside another object) in Python and then add attributes to it.

I tried:

    obj = someobject
    obj.a = object()
    setattr(obj.a, &#39;somefield&#39;, &#39;somevalue&#39;)

but this didn&#39;t work.

Any ideas?

*edit:*

I am setting the attributes from a `for` loop which loops through a list of values, e.g.

    params = [&#39;attr1&#39;, &#39;attr2&#39;, &#39;attr3&#39;]
    obj = someobject
    obj.a = object()

    for p in params:
       obj.a.p # where p comes from for loop variable
 

In the above example I would get `obj.a.attr1`, `obj.a.attr2`, `obj.a.attr3`.  

I used the `setattr` function because I didn&#39;t know how to do `obj.a.NAME` from a `for` loop.

How would I set the attribute based on the value of `p` in the example above?


How can I create an object and add attributes to it?

Much like Java (or php), I&#39;m use to seperating the classes to files. &lt;br&gt;
Is it the same deal in Python? plus, how should I name the file? &lt;br&gt;
Lowercase like classname.py or the same like ClassName.py? &lt;br&gt;
Do I need to do something special if I want to create an object from this class or does the fact that it&#39;s in the same &quot;project&quot; (netbeans) makes it ok to create an object from it?

Are classes in Python in different files?

I would like to differentiate between following cases:

 1. A plain value type (e.g. `int`)
 2. A nullable value type (e.g. `int?`)
 3. A reference type (e.g. `string`) - optionally, I would not care if this mapped to (1) or (2) above

I have come up with the following code, which works fine for cases (1) and (2):

    static void Foo&lt;T&gt;(T a) where T : struct { } // 1

    static void Foo&lt;T&gt;(T? a) where T : struct { } // 2

However, if I try to detect case (3) like this, it does not compile:

    static void Foo&lt;T&gt;(T a) where T : class { } // 3

The error message is _Type &#39;X&#39; already defines a member called &#39;Foo&#39; with the same parameter types_. Well, somehow I cannot make a difference between `where T : struct` and `where T : class`.

If I remove the third function (3), the following code does not compile either:

    int x = 1;
    int? y = 2;
    string z = &quot;a&quot;;

    Foo (x); // OK, calls (1)
    Foo (y); // OK, calls (2)
    Foo (z); // error: the type &#39;string&#39; must be a non-nullable value type ...

How can I get `Foo(z)` to compile, mapping it to one of the above functions (or a third one with another constraint, which I have not thought of)?

Generic constraints, where T : struct and where T : class

`myclass` is a C++ class written by me and when I write:

    myclass x;
    cout &lt;&lt; x;

How do I output `10` or `20.2`, like an `integer` or a `float` value?

How can I use cout &lt;&lt; myclass

What is the difference between `sealed abstract` and `abstract` Scala class?
