Using Template System for CSS Designed Web Page

Using Template System for CSS Designed Web Page

In the last post on Creating Simple Template Based Website we designed a simple Template System, if you remember its layout was designed using a Table. While tables can be used to design page layout, it’s not the standard way and has got many problems associated, instead Cascading Style Sheets or CSS should be used. If at all I’m going to give an introduction to CSS now, I’d say it is a way of styling pages and page elements. Even if you don’t know about CSS (and I’m not discussing much about it here) you’ll understand this post and how CSS can be used for designing page layout.

So let’s begin!

Below is the CSS coded version of the web page that we deigned in the previous post:

<html>
<head>
<title>CSS Coded Web Page</title>
<style>
#page{
    width: 90%;
    height: 90%;
    border: 1px solid #000;
}
#header{
    height: 90px;
    border-bottom: 1px solid #000;
    background: #cccccc;
}
#content{
    width: 100%;
    height: 90%;
}
#body{
    float: left;
}
#sidebar{
    float: right;
    width: 25%;
    height: 100%;
    border-left: 1px solid #000;
}
#footer{
    width: 100%;
    text-align: center;
    border-top: 1px solid #000;
    
}
</style>
</head>

<body>
<div id="page">
    <div id="header">
        <h1>My Website</h1>
    </div>
    
    <div id="content">
        <div id="body">
            <p>Blah</p>
        </div>
        
        <div id="sidebar">
        <ul>
            <li><a href="#">Link1</a></li>
            <li><a href="#">Link1</a></li>
        </ul>
        </div>
    </div>
    
    <div id="footer"> 
        <p>Copyright &copy; 2008 </p>
    </div>
</div>
</body>
</html>

It creates a page with the same layout as the one designed with table, it looks something like the image below:

Using Template System for CSS Designed Web Page

Let’s discuss something about the code. #page, #header, #content etc. defined are CSS codes defined inside <style></style> HTML tags. Those are known as IDs (#header ones) in CSS. We’ve given special properties like border, width, height etc. to those IDs. The IDs will be used to define and divide parts of the page to have different height, width etc. now coming to the HTML part, we are dividing parts of the page with the <div> tag giving each of them different IDs as defined in CSS. This way we can define or divide various parts of a page with different areas, positions and properties such that we get the layout as required.

Having CSS hard-coded into pages though, is not a good idea especially when HTML provides an easy way to include a separately created CSS file into pages with the following code:

<link rel="stylesheet" href=”style.css” />

Now most of the things being clear, we create the different files namely header.php, footer.php, sidebar.php and style.css fior the above designed web page. [Refer to Using 'require' to Create a Simple Template System for Websites for more information.]

header.php:     

    <div id="header">
        <h1>My Website</h1>
    </div>

sidebar.php:

     <div id="sidebar">
        <ul>
            <li><a href="#">Link1</a></li>
            <li><a href="#">Link1</a></li>
        </ul>
     </div>

footer.php:

    <div id="footer"> 
        <p>Copyright &copy; 2008 </p>
    </div>
</div>
</body>
</html>

style.css:

#page{
    width: 90%;
    height: 90%;
    border: 1px solid #000;
}
#header{
    height: 90px;
    border-bottom: 1px solid #000;
    background: #cccccc;
}
#content{
    width: 100%;
    height: 90%;
}
#body{
    float: left;
}
#sidebar{
    float: right;
    width: 25%;
    height: 100%;
    border-left: 1px solid #000;
}
#footer{
    width: 100%;
    text-align: center;
    border-top: 1px solid #000;
    
}

So from the above files we can create as many pages as we’d like using the following form:

<html>
<head>
<title>CSS Coded Web Page</title>
<link rel="stylesheet" href="style.css" />
</head>

<body>
<div id="page">
    <?php require('header.php'); ?>
    
    <div id="content">
        <div id="body">
            <p>Blah</p>
        </div>
        
        <?php require('sidebar.php'); ?>
    </div>
    
<?php require('footer.php');

All the pages would have consistent looks.

Fix For Toshiba Satellite "RTC Battery is Low" Error (with Pictures)

RTC Battery is Low Error on a Toshiba Satellite laptop "RTC Battery is Low..." An error message flashing while you try to boot your laptop is enough to panic many people. But worry not! "RTC Battery" stands for Real-Time Clock battery which almost all laptops and PCs have on their motherboard to power the clock and sometimes to also keep the CMOS settings from getting erased while the system is switched off.  It is not uncommon for these batteries to last for years before requiring a replacement as the clock consumes very less power. And contrary to what some people tell you - they are not rechargeable or getting charged while your computer or laptop is running. In this article, we'll learn everything about RTC batteries and how to fix the error on your Toshiba Satellite laptop. What is an RTC Battery? RTC or CMOS batteries are small coin-shaped lithium batteries with a 3-volts output. Most laptops use

The Best Way(s) to Comment out PHP/HTML Code

PHP supports various styles of comments. Please check the following example: <?php // Single line comment code (); # Single line Comment code2 (); /* Multi Line comment code(); The code inside doesn't run */ // /* This doesn NOT start a multi-line comment block /* Multi line comment block The following line still ends the multi-line comment block //*/ The " # " comment style, though, is rarely used. Do note, in the example, that anything (even a multi-block comment /* ) after a " // " or " # " is a comment, and /* */ around any single-line comment overrides it. This information will come in handy when we learn about some neat tricks next. Comment out PHP Code Blocks Check the following code <?php //* Toggle line if ( 1 ) {      // } else {      // } //*/ //* Toggle line if ( 2 ) {      // } else {      // } //*/ Now see how easy it is to toggle a part of PHP code by just removing or adding a single " / " from th

How to Remove Bullet Points in CSS

This will be a short guide on how to remove bullet points from ordered/unordered lists with CSS, you only need two lines of CSS for this. The first removes the actual bullet points and the second one removes the space to the left, as evident from the following video: We'll also be doing some bullet beautification in the last section if that's what you are looking to do. How to Remove Bullet Points in HTML/CSS Now that we know what CSS properties actually accomplish what we want let's see how we can implement this in our HTML code. Using Inline "style" Tag (The quick and dirty way) As the title suggests, this is the quickest way to remove bullet points in which you wouldn't have to edit any CSS files (for example, for Blogger or WordPress). This method would be useful for a one-off case - just add the following " style " attribute to the list you want to remove the bullet points from: <h1>Ordered List</h1> <ol  style="list-styl
