When beginning to program it is important to know the Beautiful Code concept. This is a new concept that was introduced a couple years back.
Beautiful code is having you lines of code organised first of all, and to have a proper pattern in your code, kind of like a poem. Here is and example in JavaScript :
CL=new Array('#ff0000','#00ff00','#ffffff','#ff00ff','#ffa500','#ffff00','#00ff00','#ffffff','#ff00ff')
CL2=new Array('#ffa500','#00ff00','#FFAAFF','#fff000','#fffffF')
Xpos=130;
Ypos=130;
I='#00ff00';
C=0;
S=5;
H=null;
W=null;
Y=null;
NS4=(document.layers);
NS6=(document.getElementById&&!document.all);
IE4=(document.all);
A=14;
E=120;
L=null;
if (NS4){
for (i=0; i < A; i++)
document.write('<LAYER NAME="nsstars'+i+'" TOP=0 LEFT=0 BGCOLOR='+I+' CLIP="0,0,2,2"></LAYER>');
}
if (NS6){
window.document.body.style.overflow='hidden';
for (i=0; i < A; i++)
document.write('<div id="ns6stars'+i+'" style="position:absolute;top:0px;left:0px;height:2px;width:2px;font-size:2px;background:'+I+'"></div>');
}
if (IE4){
document.write('<div id="ie" style="position:absolute;top:0px;left:0px"><div style="position:relative">');
for (i=0; i < A; i++)
document.write('<div id="iestars" style="position:absolute;top:0;left:0;width:2px;height:2px;background:'+I+';font-size:2px"></div>');
document.write('</div></div>');
}
function Fireworks(){
H=(NS4||NS6)?window.innerHeight:window.document.body.clientHeight;
W=(NS4||NS6)?window.innerWidth:window.document.body.clientWidth;
Y=(NS4||NS6)?window.pageYOffset:window.document.body.scrollTop;
for (i=0; i < A; i++){
if (IE4)L=iestars[i].style;
if (NS4)L=document.layers["nsstars"+i];
if (NS6)L=document.getElementById("ns6stars"+i).style;
var F = CL[Math.floor(Math.random()*CL.length)];
var RS=Math.round(Math.random()*2);
L.top = Ypos + E*Math.sin((C+i*5)/3)*Math.sin(C/100)
L.left= Xpos + E*Math.cos((C+i*5)/3)*Math.sin(C/100)
if (C < 110){
if (NS4){L.bgColor=I;L.clip.width=1;L.clip.height=1}
if (IE4||document.getElementById)
{L.background=I;L.width=1;L.height=1;L.fontSize=1}
}
else{
if (NS4){L.bgColor=F;L.clip.width=RS;L.clip.height=RS}
if (IE4||document.getElementById){L.background=F;L.width=RS;L.height=RS;L.fontSize=RS}
}
}
if (C > 220){
C=0;
var NC = CL2[Math.floor(Math.random()*CL2.length)];
I=NC;
E=Math.round(100+Math.random()*90);
Ypos = E+Math.round(Math.random()*(H-(E*2.2)))+Y;
Xpos = E+Math.round(Math.random()*(W-(E*2.2)));
}
C+=S;
setTimeout("Fireworks()",10);
}
Fireworks();

As you can see in that example the HTML is separated every line you make and every opening and closing tag line up. This makes it easy for an other programmer to understand as well with the computer. Also you need you code to be short and concise. One big reason is if you have a long line of code you can't find anything is that line because it is so extended and long. Its not all only t=just organising the code but it is looking a the artistic side of the code and understanding it.
If you do not understand this concept don't be afraid to ask questions!
