(e.g. when the user selects a country and a selection list must contain the cities in this country,
or when the user selects a singer and a selection list must contain his/her songs).

Unfortunately, the usual way of creating a selection list with a large number of items is quite slow in Internet Explorer.
In the followings, you can find solutions and speed tests for the problem (the speed test was run on an average computer).

Example 1, the usual way.

This example uses the createElement and appendChild methods to create a selection list with 2000 options: 
var select = document.createElement ("select");
for (var i = 0; i < 2000; i++) {
    var option = document.createElement ("option");
    option.text = i;
    select.appendChild (option);
}
container.appendChild (select);

Remarks:

The example does not work properly in Internet Explorer, it creates a selection list with 2000 empty options.

Example 2

This example uses the createElement and add methods to create a selection list with 2000 options: 
var select = document.createElement ("select");
for (var i = 0; i < 2000; i++) {
    var option = document.createElement ("option");
    option.text = i;
    select.options.add (option);
}
container.appendChild (select);

Example 3

This example uses the innerHTML property to create a selection list with 2000 options: 
var select = "<select>";
for (var i = 0; i < 2000; i++) {
    select += "<option>" + i + "</option>";
}
select += "</select>";
container.innerHTML += select;

Speed test:

Browser Time
IE 6 70 ms
IE 7 78 ms
IE 8 15 ms
Firefox 59 ms
Opera 16 ms
Safari 17 ms

The solution implemented by Example 3 works much more faster than the previous ones in Internet Explorer and it is also fast in other browsers.
Unfortunately, the processing time grows drastically for greater number of options in Internet Explorer.
This behavior is independent of the select and option elements, it is based on the speed of string concatenations.

But how can strings be concatenated faster?
The following examples answer that question.

Example 4

This example same as the previous one, but it creates a selection list with 8000 options: 
var select = "<select>";
for (var i = 0; i < 8000; i++) {
    select += "<option>" + i + "</option>";
}
select += "</select>";
container.innerHTML += select;

Example 5

This example creates an array from the substrings first then concatenates the array elements with the join method: 
var selectArr = new Array ();
selectArr.push ("<select>");
for (var i = 0; i < 8000; i++) {
    selectArr.push ("<option>" + i + "</option>");
}
selectArr.push ("</select>");
container.innerHTML += selectArr.join ("");

The question is, how can you set the position of an element to align to the coordinates of the mouse pointer?

The answer seems simple, the cross-browser clientX and clientY properties of the event object retrieve the position of the mouse pointer relative to the top-left corner of the browser window’s client area.

Additionally, the position of a fixed positioned element’s top-left corner can be specified with the top and left style properties relative to the top-left corner of the browser window’s client area.
All right, let’s look at a simple example first: 

<head>
    <style>
        #flying {
            position: fixed;
        }
    </style>

    <script>
        function UpdateFlyingObj (event) {
            var mouseX = Math.round (event.clientX);
            var mouseY = Math.round (event.clientY);

            var flyingObj = document.getElementById ("flying");
            flyingObj.style.left = mouseX + "px";
            flyingObj.style.top = mouseY + "px";

        }
    </script>
</head>
<body onmousemove="UpdateFlyingObj (event);">
    <div style="height:1000px;">
        The flying object also works for document scrolling.
    </div>

    <img id="flying" src="flying.gif" />

Unfortunately the previous example does not work in Internet Explorer 7 at non-default zoom levels.
The problem is that the clientX and clientY properties retrieve the position of the mouse in physical pixel size, while in Firefox, Opera, Safari and in Internet Explorer from version 8 they return the position in logical pixel size.

What does it mean?

If the browser is not at the normal zoom level (the user has the ability to zoom in or out a web page: CTRL and +, CTRL and -),

  • the position of the mouse pointer is calculated in the default pixel size in Internet Explorer before version 8 even if the current pixel size in the document is different,
  • from Internet Explorer 8 and in Firefox, Opera and Safari, the position is calculated in the current pixel size.

For example, if the zoom level is 200%, the logical pixel size is two times greater than the physical pixel size, so the clientX and clientY properties retrieve two times greater values in Internet Explorer before version 8 than in other browsers for the same mouse position.
In contrast to the clientX and clientY properties, the top and left style properties specify the position in logical pixel size in all browsers.
So if you want to set the position of an element to align to the coordinates of the mouse pointer, you need to known the current zoom level in IE7.

How can you get the current zoom level in IE7?

There are several JavaScript properties and methods that use physical pixel size instead of logical pixel size in IE7 (such as the clientX and clientY properties of the event object, the clientWidth, clientHeight, offsetWidth and offsetHeight properties of the html, the getBoundingClientRect and getClientRects methods).

The clientWidth, clientHeight, offsetWidth and offsetHeight properties retrieve the size in physical pixel size only for the html element, for other elements, they contain the size in logical pixel size.

So you can get the width of the body element with the offsetWidth property in logical pixel size and with the getBoundingClientRect method in physical pixel size.
Both values contain the padding, scrollbar, and the border, but exclude the margin.

The current zoom level can be determined with the help of those two values.
This method only works in Internet Explorer before version 8, the two values are the same in other browsers.

Note that if you need the current zoom level in IE from version 8, use the deviceXDPI, logicalXDPI, deviceYDPI and logicalYDPI properties.

This example is the same as the previous one, but it also works in Internet Explorer 7 at non-default zoom levels: 
<head>
    <style>
        #flying {
            position: fixed;
        }
    </style>

    <script>
            // always return 1,
            // except at non-default zoom levels in IE before version 8
        function GetZoomFactor () {
            var factor = 1;
            if (document.body.getBoundingClientRect) {
                    // rect is only in physical pixel size in IE before version 8
                var rect = document.body.getBoundingClientRect ();
                var physicalW = rect.right - rect.left;
                var logicalW = document.body.offsetWidth;

                    // the zoom level is always an integer percent value
                factor = Math.round ((physicalW / logicalW) * 100) / 100;
            }
            return factor;
        }

        function UpdateFlyingObj (event) {
            var mouseX = event.clientX;
            var mouseY = event.clientY;

            if (navigator.appName.toLowerCase () == "microsoft internet explorer") {
                    // the clientX and clientY properties include
                    // the left and top borders of the client area
                mouseX -= document.documentElement.clientLeft;
                mouseY -= document.documentElement.clientTop;

                var zoomFactor = GetZoomFactor ();
                if (zoomFactor != 1) {  // IE 7 at non-default zoom level
                    mouseX = Math.round (mouseX / zoomFactor);
                    mouseY = Math.round (mouseY / zoomFactor);
                }
            }

            var flyingObj = document.getElementById ("flying");
            flyingObj.style.left = mouseX + "px";
            flyingObj.style.top = mouseY + "px";
        }
    </script>

The previous two examples do not work in Internet Explorer 6, since it does not support fixed positioned elements.
If you need an example that works in IE6, too, please see the pages for the clientX and clientY properties.

of various elements is displayed.

With these properties you can set the color or the image displayed as the background.
In addition, you have control over the position, the repetition type (horizontal, vertical, both or neither) of the image.
Furthermore, you can set whether the image should scroll with the contents or should stay in a fixed position during scrolling.
In this article, you can see these functionalities demonstrated in examples among other things.

CSS background properties were introduced to substitude the background related HTML attributes such as:

(Note: that is the reason all of these attributes are deprecated in the W3C HTML 4.01 specification).

See what you can do with an element’s background.

1. How to specify a single color as the background for an element.

<head>
    <style>
        .redBg {
            background-color:#FF0000;
            /* or background:#FF0000; - shorthand property */
            /* or background-color:red; - predefined color value, not recommended */
            width:200px;
            height:200px;
        }
    </style>
</head>
<body>
    <div class="redBg">An element with red background.</div>
</body>

You can specify a background color with the shorthand background
or with the background-color property. If you want to specify only a simple color as the background,
the use of the background-color property is recommended,
because it results in more readable code.

Colors can be specified in CSS in three different ways, by using the RGB method, hexadecimal color values and predefined color names. For further details, please visit the
colors page.

2. How to use a single image as the background.

This is the case when you want to use the whole or a part of an image as the background.

Sample image:

The image can be in GIF, PNG, JPG or BMP format. Recommended are the GIF, JPG or PNG formats depending on the dimensions of the image
(check the size (lower is better) and the quality of the image).

You can specify a background image with the shorthand background
or with the background-image property. In the followings, you can see how. 

<head>
    <style>
        .single_image {
            background:transparent url(images/bg_image.jpg) top left no-repeat;
            width:200px;
            height:69px;
        }
    </style>
</head>
<body>
    <div class="single_image">An image as the background.</div>
</body>

Note: The image that is used as background cannot be resized from CSS; regardless of the size of the element, the image is shown in its original size. 
<head>
    <style>
        .single_image {
            background-image:url(images/bg_image.jpg);
            background-repeat:no-repeat;
            width:200px;
            height:69px;

            var x = (event.offsetX)? event.offsetX : event.layerX;
            var y = (event.offsetY)? event.offsetY : event.layerY;
            var bg_move_area = document.getElementById ("bg_move_area");
            if (!event.offsetX) {
                var oParent = bg_move_area;
                var areaX = 0;
                var areaY = 0;

6. How to place a background image in a specific position that is independent of the scroll state.

You must place the background image at a fixed position:

Using the background-image,
background-color,
background-repeat,
background-position,
background-attachment properties: 

<head>
    <style>
        .placed_bg {
            background-image:url(images/fixed_bg.gif);
            background-color:#ffefef;
            background-repeat:no-repeat;
            background-position:180px 60px;
            background-attachment:fixed;
            width:200px;
            height:200px;
            overflow:scroll;
        }
    </style>
</head>
<body>
    <div class="placed_bg">
        text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />
        Scroll this div!<br />
        text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />
        text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />
    </div>
</body>

Using the shorthand background property: 

<head>
    <style>
        .placed_bg {
            background:#ffefef url(images/fixed_bg.gif) 180px 60px no-repeat fixed;
            width:200px;
            height:200px;
            overflow:scroll;
        }
    </style>
</head>
<body>
    <div class="placed_bg">
        text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />
        Scroll this div!<br />
        text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />
        text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />text...<br />

7. How to create a transparent background

a, How to create an element with a transparent background:

Most HTML elements’ background is transparent by default, but you can set it directly with the
background-color property: 

<head>
    <style>
        body {
            background-color:#72b429;
        }

        .trans_elem {
            background-color:transparent;
            border:1px solid #787878;
        }

        .non_trans_elem {
            background-color:#ffffff;
            border:1px solid #787878;
        }
    </style>
</head>
<body>
    <div class="trans_elem">Some content within a transparent element</div>
    <div class="non_trans_elem">Some content within a non-transparent element</div>
</body>

b, How to use a transparent image as the background:

Image types that can be used:

  1. GIF (Graphics Interchange Format)

    The GIF format allows only one of the colors in the palette to be fully transparent.
  2. PNG (Portable Network Graphics)

    The PNG image format supports alpha channel values for any palette entry. What does that mean?
    It means that all colors can be transparent with different opacity.

1, One-color transparency (e.g. sharp edges)

The example GIF (without the checkered background):

Using the background-image,
background-color,
background-repeat,
background-position properties: 

<head>
    <style>
        body {
            background:url(images/bg.gif) repeat;
        }
        .trans_bg_img {
            background-image:url(images/rounded.gif);
            background-color:transparent;
            background-repeat:no-repeat;
            background-position:top left;
            width:80px;
            height:23px;
            color:#f6f6f6;
        }
    </style>
</head>
<body style="background:url (images/bg.gif) repeat;">
    <div class="trans_bg_img">rounded</div>
</body>

Using the shorthand background property:

<head>
    <style>
        body {
            background:url(images/bg.gif) repeat;
        }
        .trans_bg_img {
            background:transparent url(images/rounded.gif) top left no-repeat;
            width:80px;
            height:23px;
            color:#f6f6f6;
        }
    </style>
</head>
<body>
    <div class="trans_bg_img">rounded</div>

2, Alpha chanel

The example PNG (without the checkered background):

In the following examples, some workaround is ncessary to display a transparent image correctly in older Internet Explorer versions (versions before 7).
We use a conditional comment for version detection in Internet Explorer.

Note: The element must have a layout (hasLayout) if you are going to use the AlphaImageLoader Filter. 

<head>
    <style>
        body {
            background:url(images/bg.gif) repeat;
        }
        .trans_bg_img {
            background:transparent url(images/rounded.png) top left no-repeat;
            width:80px;
            height:23px;
        }
    </style>
    <!--[if lt IE 7]
        <style>
            .trans_bg_img {
                background-image:none;
                filter:AlphaImageLoader (src='images/rounded.png', sizingMethod='scale');
            }
        </style>
    <![endif]-->
</head>
<body>
    <div class="trans_bg_img">rounded</div>
</body>

8. What you can’t do (at this time) with CSS background

  • An element with multiple backgrounds. (Only workaround possible with positioned elements. Elements must be placed above the others.)
  • You can’t change the dimensions of the original image used as background. Its horizontal and vertical size is independent
    of the dimensions of the element for which it is used as background.
  • You cannot specify the horizontal or vertical starting position of the repetition of an image if the image is repeated; the
    background-position is automatically set to left top.

It’s only by accident, I wanted to make a top 10 list, but I just couldn’t miss any font that I like.

Text content is the biggest part of an informative website, so it’s particularly important to choose the perfect font and textual layout.
That is even more true when using pre-made templates.
The easiest way to make your site unique is to use custom fonts.

How to embed a custom font into your website in all browsers?

See this tutorial.

The 13 fonts showcased in the post are my favorites from the several thousands available on the market, because of their readability and legibility.
I’ve found them very useful and thought I’d share them with you. Enjoy! :)
Note: The most of these fonts only contain English characters!!!
