In the world of web programming HTML (Hyper Text Markup Language) and CSS (Cascading Style Sheets) are the most basic and essential elements to creating a web page. When starting a website from scratch these are the languages that everyone should be familiar with in order to achieve what they want from a website, or let somebody do the work for them.
To those who area already familiar with CSS and what it does, there are a few techniques regarding website design that are used almost all of the time. Some are standard, some are customize according to the programmer’s needs and some are still debatable. CSS image replacement is one technique that can be categorized in all three of the above.
There are many pros of CSS image replacement and programmers will always find something to comment on it. The cons of CSS image replacement almost balance out the benefits and it all depends on who uses the technique and which method exactly.
Known probably as the most widely-used technique of them all is to use a background image to replace the text within CSS. There are pros and cons to CSS image replacement this way that and they mostly involve the text that will have to be hidden behind the image using special CSS tags. This makes the text completely inaccessible after hiding it.
The Span tag is preferred by many when it comes to replacing text with images in CSS because it can be re-used somewhere else within the same page of the entirety of a website. The benefit of applying this method is simplifying and adding a better look to a website. However, it doesn’t really matter which method is used, because every one of them comes with risks that can manifest by using a different web browser or an outdated version for which the programmer has not been prepared or cannot prepare for.
