+Pada mulanya, web tidak memiliki elemen visual, murni teks saja. Tapi seiring   
+perkembangan peramban, laman web dengan elemen visual menjadi umum.   
+CSS adalah bahasa standar yang ada untuk menjaga keterpisahan antara   
+konten (HTML) serta tampilan-dan-kesan laman web.
+
+Singkatnya, fungsi CSS ialah menyajikan sintaks yang memampukan kita untuk   
+menyasar elemen tertentu dalam sebuah laman HTML dan menerapkan   
+berbagai properti visual bagi elemen tersebut.
+
+Seperti bahasa lainnya, CSS memiliki banyak versi. Di artikel ini, kita fokus   
+pada CSS2.0 yang meskipun bukan versi termutakhir namun paling kompatibel   
+dan didukung secara luas.
+
+**CATATAN:** Lantaran keluaran dari CSS berwujud efek-efek visual, maka untuk   
+mempelajarinya, kita perlu mencoba berbagai hal dalam dunia olah CSS semisal

+
+/* ####################
+   ## SELECTORS
+   ####################*/
+
+/* Generally, the primary statement in CSS is very simple */
+selector { property: value; /* more properties...*/ }
+
+/* the selector is used to target an element on page.
+
+You can target all elments on the page! */
+* { color:red; }
+
+/*
+Given an element like this on the page:
+
+<div class='some-class class2' id='someId' attr='value' />
+*/
+
+/* you can target it by it's class name */
+.some-class { }
+
+/*or by both classes! */
+.some-class.class2 { }
+
+/* or by it's tag name */
+div { }
+
+/* or it's id */
+#someId { }
+
+/* or by the fact that it has an attribute! */
+[attr] { font-size:smaller; }
+
+/* or that the attribute has a specific value */
+[attr='value'] { font-size:smaller; }
+
+/* start with a value*/
+[attr^='val'] { font-size:smaller; }
+
+/* or ends with */
+[attr$='ue'] { font-size:smaller; }
+
+/* or even contains a value */
+[attr~='lu'] { font-size:smaller; }
+
+
+/* and more importantly you can combine these together -- there shouldn't be  
+any spaaace between different parts because that makes it to have another  
+meaning.*/
+div.some-class[attr$='ue'] { }
+
+/* you can also select an element based on how it's parent is.*/
+
+/*an element which is direct child of an element (selected the same way) */
+div.some-parent > .class-name {}
+
+/* or any of it's parents in the tree */
+/* the following basically means any element that has class "class-name"  
+and is child of a div with class name "some-parent" IN ANY DEPTH */
+div.some-parent .class-name {}
+
+/* warning: the same selector wihout spaaace has another meaning.  
+can you say what? */
+div.some-parent.class-name {}
+
+/* you also might choose to select an element based on it's direct  
+previous sibling */
+.i-am-before + .this-element { }
+
+/*or any sibling before this */
+.i-am-any-before ~ .this-element {}
+
+/* There are some pseudo classes that allows you to select an element  
+based on it's page behaviour (rather than page structure) */
+
+/* for example for when an element is hovered */
+:hover {}
+
+/* or a visited link*/
+:visited {}
+
+/* or not visited link*/
+:link {}
+
+/* or an input element which is focused */
+:focus {}
+
+
+/* ####################
+   ## PROPERTIES
+   ####################*/
+
+selector {
+    
+    /* Units */
+    width: 50%; /* in percent */
+    font-size: 2em; /* times current font-size */
+    width: 200px; /* in pixels */
+    font-size: 20pt; /* in points */
+    width: 5cm; /* in centimeters */
+    width: 50mm; /* in millimeters */
+    width: 5in; /* in inches */
+    
+    /* Colors */
+    background-color: #F6E;  /* in short hex */
+    background-color: #F262E2; /* in long hex format */
+    background-color: tomato; /* can be a named color */
+    background-color: rgb(255, 255, 255); /* in rgb */
+    background-color: rgb(10%, 20%, 50%); /* in rgb percent */
+    background-color: rgba(255, 0, 0, 0.3); /* in semi-transparent rgb */
+    
+    /* Images */
+    background-image: url(/path-to-image/image.jpg);
+    
+    /* Fonts */
+    font-family: Arial;
+    font-family: "Courier New"; /* if name has spaaace it appears in double-quote */
+    font-family: "Courier New", Trebuchet, Arial; /* if first one was not found
+    						 browser uses the second font, and so forth */
+}
+
+```
+
+## Usage
+
+Save any CSS you want in a file with extension `.css`.
+
+```xml
+<!-- you need to include the css file in your page's <head>: -->
+<link rel='stylesheet' type='text/css' href='filepath/filename.css' />
+
+<!-- you can also include some CSS inline in your markup. However it is highly  
+recommended to avoid this. -->
+<style>
+   selector { property:value; }
+</style>
+
+<!-- or directly set CSS properties on the element. 
+This has to be avoided as much as you can. -->
+<div style='property:value;'>
+</div>
+
+```
+
+## Precedence
+
+As you noticed an element may be targetted by more than one selector. 
+and may have a property set on it in more than one.  
+In these cases, one of the rules takes precedence over others.
+
+Given the following CSS:
+
+```css
+/*A*/
+p.class1[attr='value']
+
+/*B*/
+p.class1 {}
+
+/*C*/
+p.class2 {}
+
+/*D*/
+p {}
+
+/*E*/
+p { property: value !important; }
+
+```
+
+and the following markup:
+
+```xml
+<p style='/*F*/ property:value;' class='class1 class2' attr='value'>
+</p>
+```
+
+The precedence of style is as followed:  
+Remember, the precedence is for each **property**, not for the entire block.
+
+* `E` has the highest precedence because of the keyword `!important`.  
+	It is recommended to avoid this unless it is strictly necessary to use.
+* `F` is next, because it is inline style.
+* `A` is next, because it is more "specific" than anything else.  
+	more specific = more specifiers. here 3 specifiers: 1 tagname `p` +   
+	class name `class1` + 1 attribute `attr='value'`
+* `C` is next. although it has the same specificness as `B`  
+	but it appears last.
+* Then is `B`
+* and lastly is `D`.
+
+## Compatibility
+
+Most of the features in CSS2 (and gradually in CSS3) are compatible across  
+all browsers and devices. But it's always vital to have in mind the compatiblity  
+of what you use in CSS with your target browsers.
+
+[QuirksMode CSS](http://www.quirksmode.org/css/) is one of the best sources for this.
