During last few weeks we’ve found that a few of our client’s sites are infected with malicious javascript code, which appeared to be the result of a virus work. The virus behaviour is similar to so-known Gumblar virus. Here is a short summary of what this virus does:
Our clients often ask us to add a few dynamic javascrtipt effects to their website in order to make it more attractive. Many of them look so intuitive and natural that people can think that they are very easy to add and there are common standard tools for that which you can include where appropriate. In fact the effects which look the same in browser can be coded very differently. Unfortunately there are no standards for such things in web development yet (like W3C standards for XTHML/CSS) and developers just use various JavaScript libraries which save much time for doing such things. From variety of such libraries we separate jQuery library as the one which we find the most easy to work with. It can also be extended by writing the plugins and people wrote quite a lot plugins for jQuery so far.

These days most frontend CSS-developers face with a problem of using custom fonts when coding web pages. The technology of sIFR (Scalable Inman Flash Replacement) became very popular because it gives rather flexible and easy to use solution of this problem. If you are new to this technology please check sIFR Documentation for more information.
Though sIFR gives many useful additional abilities for the developers there is one thing which is not trivial to do with sIFR. Imagine that you need to highlight some parts of the sIFR text with different color(s). The solution which cames in mind is splitting the text into several tags and applying sIFR to every tag individually. Unfortunately this doesn’t work in many cases because of impossibility to make the width of sIFR element flexible, so more elegant solution needs to be found.
If you ever tried to find ready-made solution you’ll definitely find the … read more
