People often make errors in coding which can have a bad impact on their final product as most of the times small errors are highlighted as huge mistakes in the ultimate picture. This can be particularly be seen in things like CSS, which stands for Cascading Style Sheets, is a common phenomenon nowadays especially with the use of the internet as this is the language that helps the people understand the codes that are uploaded on the website, generally, in the Hyper text mark up language (HTML).

It is used in general for all the mark up languages; the others include XML as well. But while CSS quite a few common errors can be seen which are made by people while creating a web page or a template, a few are as follows:

1. People often waste bytes by adding unnecessary information in their CSS coding which makes the entire document much heavier and hence it occupies a larger web space. More than this the document looks bigger and messier. Such things also make it difficult to detect the mistakes in a particular code and also prove fatal to your pocket as ultimately you would have to pay for every bit of web space that you take. A great example of such a CSS error is adding units to 0, it is important to understand that “0” means nothing and following it with a unit for any dimension would make no sense and would just waste important web space. The only logical explanation for adding an unit is that the person intends to alter the value from zero pretty quickly.

2. While the addition of colours to a website people make a very common mistake that makes the parsing of the hex colour code impossible. Most of the times they forget to add the # symbol which is of uttermost importance. Non performance of this step might lead to the crashing of the parser as well.

3. People who are not that well acquainted with the knowledge of CSS end up repeating a set of codes, this can be avoided by a method called condensing. This not only avoids the tedious job of repeating codes but also saves the valuable bytes on the document. Such an error is common in documents where the creator tries to insert borders, he/she ends up putting a code for each side where as a common condensed formula can be put for all sides in common.

4. Many a times people are not aware of the various styles that can be applicable to set of codes and hence end up mis-matching them leading to a situation that the final output throws out quite a few errors. Hence while creating a CSS it is important to emphasize on the correct style for a particular code.
All the above mentioned are possibly very simple for a programmer and most of them are not done due to a flaw in the person’s knowledge but they are either a result of incomplete learning or ignorance!!
