Hi all:
I've noticed that there are a couple of similar questions and answers at SO already, but let me clarify my specific question here first:
I've got lecture slides which states like this:
To be frank, I haven't heard of this rule of css precedence myself, and I googled to find something with similar topic but not quite like that : here
To have a test myself, I've made a test page on my own server here
After running it on FireFox 3.6.3, I am sure it does not show the way as it should be, according to the statement in lecture slides:
- imported stylesheet ? am I doing it wrong? I cannot see its effect using FireBug
- it says that embedded stylesheet has a higher precedence over linked/imported stylesheets, however, it doesn't work, if I put the linked/imported tag AFTER that.
- inline style vs html attributes ? I've got an image where I firstly set its inline style to control the width and height, then use direct html attributes width/height to try modifying that, but failed...
Below is the source code :
<html>
<head>
<style type="text/css">
#target
{
border : 2px solid green;
color : green;
}
</style>
<link rel="stylesheet" href="./linked.css" type="text/css" media="screen" />
</head>
<body>
<div id="target">A targeted div tag on page.</div>
<img src="cat.jpg" alt="" style="width : 102px; height : 110px;" width="204px" height="220px" />
</body>
</html>
Can any experienced CSS guys help me figure out if the slide is correct or not?
Frankly speaking, I am puzzled myself, as I can clearly see some other "incorrect" statements here and there amongst the slides, such as JavaScript is on client-side (how about server-side JavaScript?) and "Embedded styles are in the head section of a web page "(what the heck? I am not allowed to put it inside the body tag?)
Sorry about this silly question, the exam is on TOMORROW, and I now see a lot of things to think about :)
