]]> We can simply use CSS alone to reproduce opacity effect that have traditionally been done using scripting. The advantage of looking to CSS instead is obvious – much more lightweight and easier to implement. We can use this method where we need to use a dim or faint version of image, while when some one places mouse over it, then image comes sharp, clear and bright.

Use the following code in head section of web page.

<style type="text/css">
.opacityit img{
filter:progid:DXImageTransform.Microsoft.Alpha(opacity=40);
-moz-opacity: 0.4;
}
.opacityit:hover img{
filter:progid:DXImageTransform.Microsoft.Alpha(opacity=100);
-moz-opacity: 1;
}
</style>

Use the following code in body where the image is located.

<a href="#" class="opacityit"><img border="0" src="email.gif" /></a>

By this method image loads kind of blur in background and in light colors, but when some one places mouse over it. It becomes sharp.

Simple Opacity

We are using JavaScript to change the opacity of an image here. The technique works in both IE4+ and NS6+, and can be used to create some interesting “fading” effects. Here is the simple way to just place an image with opacity.

<img src="image.gif" style="filter:alpha(opacity=50); -moz-opacity:0.5">

In -moz-opacity:0.5 accepted range of values are 0 to 1, where 0 would make the image disappear and in alpha(opacity=50) range is between 1 to 100. We have combined the code both for IE and Mozilla for code compatibility.

We can also alter the opacity of image using javascript.

Head section code

<script>
function alteropacity(imageobject, opacity){
 if (navigator.appName.indexOf("Netscape")!=-1
  &&parseInt(navigator.appVersion)>=5)
    imageobject.style.MozOpacity=opacity/100
 else if (navigator.appName.indexOf("Microsoft")!= -1 
  &&parseInt(navigator.appVersion)>=4)
    imageobject.filters.alpha.opacity=opacity
}
</script>

Body Section Code

<img src="image.gif" style="filter:alpha(opacity=50); -moz-opacity:0.5" 
onMouseover="alteropacity(this, 100)" onMouseout="alteropacity(this, 30)">

]]> CSS is a simple file which controls the visual appearance of a web page without compromising its structure. Why to use it and how to use it properly. If you don’t use CSS on your web pages and you have many tables and content on them, chances are that your HTML file size will be quite heavy. Fact is that we live in a busy world, and people will not wait more than 5 seconds for web page to load. Some web developers implement the CSS on wrong way. They write their CSS in HTML code of the page, like this:

<html>
<head> 
<title>My Page</title>
<style>
A { font-family: Verdana; font-size:8pt; color:black; text-decoration:none } 
</style>
</head>
<body>some content</body>
</html>

Correct way is to link the external CSS file in the pages. i.e.

<link rel='stylesheet' href='css/styles.css' type='text/css' media='all' />

]]> I have described about using nice and clean fonts in web page. Now lets see some more details about using fonts in web pages.

As we know Verdana, Arial and Tahoma are being used from the beginning. In Web 2.0 Style, and many open source softwares such as WordPress, now-a-days some other fonts are being used which are neat and clean and stylish too. Best part is, to use these, no installation of fonts is needed. In Windows XP these are present by default. I have selected some examples of look and feel of some chosen fonts over here.

Font Families

It happens so that we can define a family of fonts while creating web page. If one font is not available in user’s machine; then next font style will be displayed. i.e

<style type="text/css">
.myfont { font-family: Geneva, Arial, Helvetica, sans-serif; }
</style>

Suppose Geneva is not present in user’s machine, then system will pick next font Arial for style. So it is recommended to use font-families.

The font-family property is a prioritized list of font family names and/or generic family names for an element. The browser will use the first value it recognizes.

There are two types of font-family values:
* family-name: The name of a font-family, like “times”, “courier”, “arial”, etc.
* generic-family: The name of a generic-family, like “serif”, “sans-serif”, “cursive”, “fantasy”, “monospace”.

Separate each value with a comma, and always offer a generic-family name as the last alternative.

If a family-name contains white-space, it should be quoted. Single quotes must be used when using the “style” attribute in HTML.

Here is the list of font families commonly available on all systems.

Arial, Helvetica, sans-serif
‘Times New Roman’, Times, serif
‘Courier New’, Courier, monospace
Georgia, ‘Times New Roman’, Times, serif
Verdana, Arial, Helvetica, sans-serif
Geneva, Arial, Helvetica, sans-serif

]]> Text like, a b c d e f and so on written in HTML will do fine in any browser, we all know that.

What about the following!
abcdefghijklmnopqrstuvwxyz….NoWordBreaksAndSentenceGoesOnAndOn…
The text with no spaces.

If there are no breaks in words then the sentence will proceed straight and cause horizontal scroll in web page. In blogs or in any other applications where users can comment or put some data, they can write such spam or anything that can cause your web page layout to break. We have a solution to that. Write text in pre tag and apply following CSS to it.

pre {
 overflow-x: auto; /* Use horizontal scroller if needed; for Firefox 2, not needed in Firefox 3 */
 white-space: pre-wrap; /* css-3 */
 white-space: -moz-pre-wrap !important; /* Mozilla, since 1999 */
 white-space: -pre-wrap; /* Opera 4-6 */
 white-space: -o-pre-wrap; /* Opera 7 */
 /* width: 99%; */
 word-wrap: break-word; /* Internet Explorer 5.5+ */
}

This will fix the problem and in IE it will cause line break and avoid horizontal scroll while in Mozilla Firefox it will add an inline frame and put all the data in it.

]]> Markup language validation is very important. Without it your web page will not be indexed in Google. Google crawlers will just avoid the invalid markup and errors in HTML. Here is a complete list of tips you can use to avoid HTML markup errors and warnings so that you write valid HTML or XHTML.

Advices For Valid Markup
  • Use (define) backgrounds in CSS, not in html, TD, TR or Table
  • Do not define height of table or tr
  • Use alt=”" at every image even at spacer and separator
  • Place form tag b4 and after table tag and not td
  • Use correct doctype i.e.
  • Use all attributes for tags, i.e. script tags and css link tags. i.e.

  • In Anchor link where u have to use & use its code like &
Advices For Valid CSS
  • Define background color with color, and for transparent use inherit i.e.
    color : #000000;
    background-color: inherit;
    Use these both even one is not necessary to define, second with inherit property
  • Use shorthand for properties
  • Use generic font family i.e.
    font-family : verdana, arial, sans-serif;
    or
    font-family : “trebuchet ms”, geneva, sans-serif;
  • For background and backgriund position use different lines. i.e.
    background: url(../images/menulinebg.jpg) no-repeat;
    background-position:left center;
