Style Rules in CSS

CSS comprises of style rules interpreted by the browser and then applied to the corresponding elements in your document. A style rule is made of three parts −

• Selector -  A selector is an HTML tag at which a style will be applied. This could be any tag like <h1> or <table> etc.
• Property - A property is a type of attribute of HTML tag. Put simply, all the HTML attributes are converted into CSS properties. They could be color, border etc.
• Value - Values assigned to properties. For example, the color property can have value either red or #F1F1F1 etc

You can put CSS Style Rule Syntax as follows:

selector { property: value }
