CSS files vs skin files

Question by just_name

Q: I want to know :

  1. Are the skin files can replace the
    CSS files?
  2. What are the advantages of
    skin files?

  3. Are those files can provide more
    brilliant things the CSS files


  4. When to use skin files in my web

Answer by Geoff Appleford skins are one part of Themes. From the MSDN docs:

Themes are made up of a set of
elements: skins, cascading style
sheets (CSS), images, and other
resources. At a minimum, a theme will
contain skins. Themes are defined in
special directories in your Web site
or on your Web server.

Skins are used to define default markup for server controls:

<asp:button runat="server" BackColor="lightblue" ForeColor="black" />

whereas CSS is used to style your native HTML elements (of course server controls render as native elements so CSS can also be used to style these

Answer by Starx

CSS Files is a .css file contains style tags nothing more (for example, page.css)

But, a theme or skin file might be a set of files containing images, icons, css files, js files which can be used or integrated as sort of a plugin to change the appearance of the Application. (for example, a joomla template)

When uploading, where do I set the php.ini parameters?

Question by gAMBOOKa

In the script where the upload form is, or the script that processes the action?

Example parameters:


EDIT: Ok, let me clarify. First, I didn’t know the 2nd, 3rd and 4th parameter could not be changed using ini_set(). Now, I want to know where exactly I should call the ini_set() function. In the form script or the action handling script?

Here’s an example to illustrate what I’m looking for:


<form action="post.php">
  <input type="text" name="search" />
  <input type="submit" />


<?php //handle search ?>

So under which file must my ini_set() function should go?

Answer by Starx

You have to set these parameters initially from php.ini. You cannot change this from a PHP script except memory_limit, for the remaining Just search for those keys you mentioned in php.ini and change their values.

For memory_limit you can use following snippet at your processing page handling the uploads like in your case at post.php



You can create a .htaccess file at the root directory, if your server support mod_rewrite modules you can change them like this

php_value upload_max_filesize 20M
php_value post_max_size 20M
php_value max_execution_time 200
php_value max_input_time 200

How do I get a div background image to scroll?

Question by liamacheung

I want the background image of a div (with id=”library_tracks”) to be repeated in both x and y directions and to scroll with the div. For whatever reason, the background is staying fixed. I imagine the solution is pretty straight forward… any ideas?

Here’s my CSS:

#library_tracks {
    overflow-y: scroll;
    height: 400px;
    border: thin solid #DADADA;
    background-image: url('../img/track_background.png');
    background-attachment: scroll;


Answer by somethingkindawierd

The trick is to set the background not on the container div, but on the content div within it. Here’s a working example where the <div id="library_tracks"> div displays the scrollbar, but the <div id="content"> is the actual content that’s moved.

This works because it’s the content div that moves. The library_tracks div is stationary, but everything in it scrolls.

Answer by Starx

A entire divison will scroll on only one circumstance i.e. the contains does not fit within the division area.

Whether you have small background images or big one, if the content can fit within the div we will not get the scrolling even if you set the overflow option.

Adding to browser context menu?

Question by Blender

Is it possible to add item to the default browser right button click menu?

Answer by alex

No, but you can create your own.

Look at the event oncontextmenu().

Here is some good further reading.

Answer by Starx

You can’t modify the client’s application using a web page. If this would be possible, just think about how hackers could exploit our computer.

What you can do, is define your own custom menu, while user right clicks.

The most semantic way of making this container

Question by theorise

I want to make the following shape using divs and border radius, with fall back to square corners for old browsers. No images please.

I am having a bit of trouble making the bottom corner next to the title (highlighted with the red box). I don’t want a lot of unnecessary divs, it has to be as simple and semantic as possible.
alt text

<div class="container">
   <div class="header">Title</div>
   <div class="body">Content</div>

.container{width: 660px; background: #fff;}
.container .header{float: left; width: 110px; background: #333; border-radius: 5px 5px 0 0;}
.container .body{clear: left; width: 660px; background: #333; border-radius: 0 0 5px 5px;}

Any ideas?


I did it like this:

<div class="container">
    <div class="header"></div>
    <div class="headerspacer">
       <div class="headercorner"></div>
    <div class="body"></div>

.container{width: 660px; background: #fff;}
.container .header{float: left; width: 110px; height: 30px; background: #333; border-radius: 10px 10px 0 0;}  
.container .headerspacer{float: left; position: relative; width: 550px; height: 30px; background: #333;} 
    .container .headerspacer .headercorner{ position: absolute; width: 550px; height: 30px; background: #fff; border-radius: 0 0 0 10px;} 
.container .body{clear: left; width: 660px; height: 100px; background: #333; border-radius: 0 0 10px 10px;}


I am going to use this method:

I also found a method of using an image which will not appear if the browser does not support rounded corners. It is much more semantic, and the whole point of using border-radius is to negate unnecessary markup. I think I will actually use this method, but I won’t accept it as an answer as I stated that I do not want images.

<div class="container">
    <div class="header"></div>
    <div class="body"></div>

.container{width: 660px; background: #fff;}
.container .header{float: left; width: 110px; height: 30px; background: #333; border-radius: 10px 10px 0 0;}                                  
.container .header:after{content: url(; display: block; margin: 20px 0 0 110px;}
.container .body{clear: left; width: 660px; height: 100px; background: #333; border-radius: 0 0 10px 10px;}

Answer by alxx

My idea was white rounded div with dark background under bottom left corner. (I can’t get it to work myself, so it would be great to see result 🙂 )

Correct HTML scrolling element of main viewport (+jQuery)

Question by tillda

When I want to scroll a website by javascript code what is the corrent element to set the .scrollTop property on?

Is it window, document, document.body or html element?

Does jQuery have some trick to detect the intention to scroll the main viewport and unify the calls? It seems to me that sometimes $(window).scroolTop(value) works, but sometimes it doesn’t.

Answer by bobince

Normally, the <html> element, aka document.documentElement. However if you are using Quirks Mode, <body> (document.body) represents the viewport instead. (HTML/CSS doesn’t explicitly state/require this, but it is how all modern browsers work.)

You don’t ever want to be in Quirks Mode, but if you’re writing a script for inclusion on other people’s pages you will have to deal with it:

var viewport= document.compatMode==='BackCompat'? document.body : document.documentElement;
// do something with viewport.scrollTop

jQuery uses window.scrollTo() instead of setting the scroll properties directly. Either way is pretty much the same in practice. You could argue that using scrollTo is a bit cleaner in that it avoids relying on the viewport being represented by a particular element, but then jQuery still has to use scrollTop/scrollLeft to read the current value of the ‘other’ property anyway, so no big win. You can use pageXOffset/pageYOffset to read the current scroll position without relying on a particular element, but it’s not supported everywhere so you still have to fallback to the scrollTop method.

Sadly none of these properties/methods have been standardised in the past. CSSOM Views finally address this.

Answer by Starx

Depends on what you are scrolling, document/Window or a division

jQuery resizable plugin, to resize only height

Question by Goppie TOp

How to make alsoResize option to only work for height but not for both width and height?

Answer by Starx

Actually if you set maxWidth to a limit, we cannot resize the width more than it.

For example,

$( ".selector" ).resizable({ maxWidth: 250 }); //For initialzation 

will not allow the resize to occur more that 250px in width

If you check this demo, you will notice the width resizing being limited to a point.

So in your case set the initial width of the .selector and maxWidth same and it is done.
