You might have read about my earlier post on CSS introduction. This article is a continuation to my earlier article. Without wasting much time, lets have a look at an example of a CSS code and then analyze it.
selector {
property1:value;
property2:value;
property3:value;
}
The relevant parts are as follows:
The Selector
The selector is a part of a CSS that identifies the HTML elements in which the rule will be applied to. Identification is done by the actual element name such as body, sidebar, footer, etc. More details will be discussed later on.
The Curly Braces “{“ “}”
These curly braces envelop the property/value pairs which are separated from one another by semi-colons (;) while the properties are separated from their respective values by colons (:).
The Properties
The properties define what you want to do with the element or elements you have selected and they come in wide varieties. These varieties can affect element color, position, background color, margins, font type, padding, etc.
The Values
The values as in context to CSS are the values that you want to change or assign to each property of the elements selected. Values are dependent on properties. As for instance, properties that affect color can use up hexadecimal colors like #4459ff, color names like red, green, blue, yellow, etc. or RGB values like rgb(132,55,44).
Properties that can change position, borders, height, width, etc. can be measured in pixels, percentages, ems, centimeters, inches, etc.
Here is one example to a CSS code:
p {
margin:4px;
font-family:verdana;
color:green;
}
The HTML element that this rule selected is p i.e. every p element in the HTML document or documents that uses this CSS. All p element in the HTML documents that uses this CSS will have the rule applied to it. If more specific rules are applied to them, the specific rule will overwrite the current rule. As per the rule above, the properties affected are the font inside the paragraphs, margins around the paragraphs and the color of the text. The margins here are set at 25 pixels, font is Verdana and the color of the text is green.
We will be coming back to all these in detail later. To know more about Cascading Style Sheet in detail, keep visiting back. Not only CSS, you can also read about Android application development, iPhone application development, etc. from my article section.
