Internet Explorer Web browser is probably the most criticized in the history of the Web. Yet it is the source of some exciting technologies such as “CSS expressions, which could make life much easier for developers if competitors of Internet Explorer were implemented.
CSS expressions, what it is?
You did not say that CSS was very limited? It was sometimes necessary to review the entire architecture of your site in order to ensure that the left menu and body always do exactly the same height while remaining expandable? In any case, it had to work the developers of Internet Explorer.
height: expression (document.getElementById (‘body’). style.height);
A small piece of code that will give very short in our menu is the same height as the html element with ID # Corps. Depending on how you designed your design, it may be difficult or impossible to achieve something similar with CSS simple, while ensuring that the height of # body is proportional to its content. Nice, right?
Technology reduced to … hacks?
Despite the many advantages offered by the terms of Microsoft, they are not widely used on the Web, except … to address some of the rendering engine of Internet Explorer? At this point the ticket, I want to reiterate that the terms are understood only by Internet Explorer.
Thus, their use is rather difficult for Webmasters interested in maintaining compatibility between different browsers. However, these terms are still used to fix bugs specific to Internet Explorer, or to emulate certain CSS properties (such as “max-width”) does not support it, unlike its main competitors. The code below has the property max-width “for sailors who know her, and adds an expression to Internet Explorer 6, which does not know this property has a similar behavior.
max-width: 200px; / *
– This value will be understood by Firefox, Safari, Opera, … * /
width: expression (this.width> 200? “200px”: this.width + “px”) / *
– Expression for Internet Explorer * /
You will understand that this expression is therefore understood by Internet Explorer, which she explicitly states that the maximum width of # menu is 200 pixels, while the third-party browsers like Opera, Firefox or Safari, will ignore the property max-width and simply they will not understand. This is the main use of a technology that many utilities, however third.Tagged With simplify using internet explorer
