All about BB Code
Dec 21st
BB Code is a common way for format blog posts, forum posts, and comments on those posts. BB Code is an acronym for bulletin board code. If you are familiar with HTML code then BB Code will be very easy for you to understand. If not then need not worry, we will be covering all of the essential info you’ll need to know.
BB Code is an alternative to using HTML in user input forms. BB Code is a “safer” alternative to HTML, for when you have unknown users making posts on your site and you want to protect from the users trying to do anything malicious. Ultimately the BB Code, is converted into normal html, usually by a php script, so that the browser can interpret it.
Like HTML, BB Code has tags or key words or characters placed within a tag that contain a special meaning. Example:
| HTML/CSS | BB CODE |
|---|---|
| <b> bold text | [b]bold text[/b] |
| <i> italic text | [i]italic text[/i] |
| <u> underline text | [u]underlined text[/u] |
| text-decoration:line-through; strikethrough text | [s]line-through text[/s] |
| font-size:value; some text | [size={number}]text[/size] |
| color; some text | [color={color}]text[/color] |
| text-align:center; some text | [center]centered text[/center] |
<blockquote>some text |
[quote]blockquote[/quote] |
| <a href="url"> this is a link | [url={url}]link title here[/url] |
| <img src="img" /> {image} | [img]{url}[/img] |
|
<img src="img" height="#" width="#" /> Resized Image |
[img{width}x{height}]{url}[/img] |
| <ul> unordered list | [ul][li]{text}[/li]…[/ul] |
| <ol> ordered list | [ol][li]{text}[/li]…[/ol] |
| <code> monospace text | [code]{text}[/code] |
| <table><tr><td></td></tr></table> | [table][tr][td][/td][/tr][/table] |
For those that know HTML you see the similarities. For those you who are not, we can see how certain words or characters are encased in brackets [] and they have a special meaning. An alternative to BB Code is a HTML Filter that will not allow javascript and other tags.
Differences between HTML and BB Code
| HTML | BB CODE |
|---|---|
| Angled brackets <> | Rectangular brackets [] |
| Allows inline CSS by use of the style attribute | Does not allow any inline CSS to be used |
| Chances of executing JavaScript or breaking the layout of a website | No chance of executing JavaScript or breaking the layout of the site |
| Formatting is very picky and cannot be changed | Formatting is simple and easy to understand and to change |
| There is a standard | There is not a standard |
BB Code is used in many forum softwares and content management systems.
Advanced CSS – Part #4
Dec 18th
In this tutorial we’re going to talk about the float property. For this tutorial you will need to be familiar with the Basics of CSS and you should be familiar with the Advanced CSS tutorials until this point.
Float Property
The float property allows for an element to be pushed to the left or the right so other elements can wrap around it. Floated elements can only be moves horizontally (left or right). All floated elements will move as far right or as far left as it possibly can; this is dependent upon the nature of the container that the element is in.
Values
- left – floats element to the left
- right – floats element to the right
- none – specifies no floating
Consider the following code:
body { margin:auto; width:1000px; background-color:#4c4c4c; font:verdana, "Times New Roman", san-serif; font-size:11px; color:#fff; } #container { width:300px; background:transparent url('image/img.jpg') repeat-x; min-height:125px; float:right; }
We have made the body element have a width of 1000px (the rest of the styles are irrelevant) and then we defined an ID selector that has a width of 300px and a min-height of 125px (it has to be at least 125px tall) and this element will be pushed to the edge of the right side of the container.
Since floated elements allow other elements to wrap around the floated element. All elements before the float property will not be affected, however, all element thereafter the float property will be affected. Consider the following code:
body { /*...*/ } #container { width:300px; background:transparent url('image/img.jpg') repeat-x; min-height:125px; float:right; } .float-right {float:right;}
<html> <body> <div id="container"> <p>This element will be on the right edge of the page that is 1000px across.</p> </div> <p>This is some text</p> <img src="image/img.gif" height="100" width="100" alt="img" class="float-right" /> <p>This is some text</p> </body> </html>
This example would allow for the text to wrap around “img.gif” no matter what size the image is (in the case of the example it is 100px by 100px).
Floating Elements
As we mentioned before, floating an element will push the element to the right or left side of the container if possible. Consider the following code:
.fancy { width:500px; float:left; }
<h2>Title here</h2> <div class="fancy"> <img src="img.gif" height="64" width="64" alt="img" /> <p>Description here</p> </div>
This will put the image inside of an area of 500 px wide and infinitely tall (depending the amount of content in that class selector).
Clear Property
How do we “turn off” floated elements? The clear property specifies which sides of a floated element you want to keep clear of other floating elements.
Values
- left – clears the left side of the element
- right – clears the right side of the element
- both – clears both the left and right side of the element
- none – does not clear either side of the element
Consider the following code:
<html> <head> <style type="text/css"> .clearfix {clear:both;} .fancy { width:500px; float:left; margin:5px; } </style> </head> <body> <div class="fancy"> <h2>Fancy Pictures</h2> <img src="img.gif" height="64" width="64" alt="img" /> <img src="img2.gif" height="64" width="64" alt="img" /> <img src="img3.gif" height="64" width="64" alt="img" /> <img src="img4.gif" height="64" width="64" alt="img" /> <img src="img5.gif" height="64" width="64" alt="img" /> <p class="clearfix">Some explanatory text here</p> <img src="img6.gif" height="64" width="64" alt="img" /> <img src="img7.gif" height="64" width="64" alt="img" /> </div> </body> </html>
In the code above, you would have all of the styles we defined in the fancy class and then a break of text where no floated element is allowed (neither left or right). This will clear a space for the explanatory text where no floated element will exist. This can be useful for adding more titles or text to the “fancy” class we created.
