Website Designers and Webmasters

You’ve probably heard “iframes are horrible with search engines.” Well, they are.

I recently had a client want me to create scroll boxes for their website so they could fit 1000+ words into a 300×457 pixel scroll box. How can I create this scroll box without the iframe? Well, you are about to find out.

CSS Scroll Box Instead of an iframe:

We’re going to use a css property called “overflow,” and by setting it to auto, it turns a normal div into a scroll box!

#scrollbox {
width:300px;
height:457px;
overflow:auto;
}
<div id=”scrollbox”> *enter endless amounts of words*</div>

So what just happened there is we assigned a div with a fixed width and a fixed height. Normally, if you had an element (ie image or text) that was too big for those dimensions, the element will be pushed larger. By adding the CSS scrollbox property of “overflow:auto” we tell the div to create a scrollbar instead of changing the size of the div.

The CSS property “overflow” does have a possible value of “scroll”, but this adds a permanent scrollbar to the bottom and right-hand side of the div even if you don’t need them. This “auto” value is great because if your content isn’t larger than the div, no scrollbars will appear. And if your content only stretches horizontally, you will only see a horizontal scrollbar!

That’s it!

This is what I call CSS tip in 30 seconds:

It is very useful to be able to put your navigation bar or side bar at the bottom of your HTML, and absolute position it to appear up on your site where you want it to go. This is actually pretty easy.

If you just want it to be along the left side of your screen and lets say 100 pixels from the top (for your header), this would be your code:

#leftnav {
position:absolute;
top:100px;
left: 0;
}

If you want your navigation bar to go along the right, obviously you would replace “left” with “right”.

Here is where it can get complicated: What if your layout is a fixed width, centered layout? Then you cant just align the navigation bar off to one side, because that would not stay inside of your layout, it would jump all the way off to the side. Here’s what you would do for a 1000 pixel width and centered website layout:

#leftnav {
top:100px;
right: 50%;
margin-right: -500px;
}

Quick Explanation: “right:50%” causes the right side of your navigation bar to be exactly in the middle of your screen. It doesn’t matter what size screen you have, it will always be right in the middle. Then the “margin-right:-500px” moves the entire navigation bar 500 pixels to the right. So in essence, the navigation bar will always be 500 pixels to the right of the exact middle of your browser! That way it looks permanent, and won’t move as you shrink your screen.

Another Note: If your navigation bar is going to the left side of your screen, here is another option: If you leave the side bar or navigation bar without the absolute positioning, and it appears directly below where you want it, then if you leave off the “right” or “left” in your CSS (leaving only “top:100px”) your navigation bar will move straight up to the top of the screen, and stay where you need it to be.

Cascading Style Sheets (CSS) make it very easy to replace text with an image. Here is the whole process described in as few words as possible:

Background Information

In CSS, “display:none” will cause that element and every child in it to disappear. There is nothing you can do to make one of the child’s element.
“background-image” give an element a background. This can be applied to just about every element.

Create the Elements in HTML

In your HTML, write this:

<h3 id=”title”>
<span>Here is the Title!</span>
</h3>

Create the CSS to replace the text with an image

In your CSS, write this:

/* Remove the Text */
#title span {
display:none;
}

h3#title {
background: url(”image/url.jpg”) no-repeat top left;
height: 20px;
width: 100px;
}

And Bam! Your text has disappeared off of the page, and the H3 element is 20 pixels wide and 100 pixels tall. It also has an image for a background that is aligned in the top left corner.

I’ve seen that CSS Text Replacement technique described with two pages, so I thought I’d see how short of a blog I could make out of it.

And Now you know how to replace text with an Image!

On a side Note, I’ve also seen this done with: “text-indent: -5000px;” or “visibility:hidden”. These work, but I would stick with display:none. It’s the cleanest way to do it.

Absolute Positioning with CSS can be a very useful thing.

I’ve been working a lot with CSS over the last year, but I’ve just recently discovered the secret to absolute positioning.

Absolute Positioning in CSS

Absolute positioning will allow you to move an HTML item from anywhere in your code to the same spot. For Example: The side bar on this page (Top Horse Connection) is at the very bottom of the HTML code. But the CSS absolute positioning tells the side bar to be positioned 170 pixels from the top of the page. Here is the CSS Code:

#sidebar {
position:absolute;
top: 170px;
left:0;
}

As you can see, it’s very simple. And it’s very useful when you want something to align along the right or left side of the screen. But what if you want a sidebar to be positioned in the middle of your screen (lets say 300 pixels to the left of the exact middle)?

You could do:

#sidebar {
position:absolute;
top: 170px;
left:400px;
}

On a 1400 pixel-wide-screen, that would work perfectly!, but what if your screen was 800 pixels wide, then the sidebar would be 100 pixels to the right of the middle… So what now?!?!

This is what would you do:

#sidebar {
position:absolute;
top: 170px;
left: 50%;
margin-left: -300px;
}

And Wala!

What is CSS Zen Garden?

It’s a great idea, thats what it is. It’s the ultimate Test of a CSS Designer. They have one basic HTML file, that is free to download, but you’re not allowed to change it. The only thing you are allowed to change is the css (which is all you need), and people create the coolest designs using only CSS!

Introduction to Cascading Style Sheets

HTML is very functional, and you can do a lot with it, but there are two large down sides to it. It’s purposes is solely for formatting, and it clogs up your HTML documents with a lot of code. Adding a Cascading Style Sheet to your website not only makes it way easier to format( and change at a later date). It also simplifies to the code like nothing else.

I recently did a Search Engine Optimization on a site called: Clear Lake Guide Service. The previous website used about 100 lines of code for the header… Using CSS, I cut that down to 20 lines of code. It keeps the Search Engines happy, and the website designers happy.

So needless to say, you can do almost anything with CSS!

Now back to CSS Zen Garden:

Zen Garden takes submission from website Designers from all over the world. And every design looks like a completely different website, even thought the XHTML is EXACTLT the same as all of the others! Right now they are getting close to 1000 submissions! If I have a free hour, I’ll throw one together as well.
