When you are writing CSS (Cascading Style Sheet) code, you are writing a set of rules that a page's HTML code must follow when rendering the page.
Every block of CSS rules has three important parts: The selector, properties, and values. The selector is what tells the page WHAT elements the following rules apply to, such as all divs with a name of "colorMeRed". Properties are what the page must change on the element, such as it's color. Finally, the value is what that property actually must be set to, such as "red".

What the concept lies behind ruleset in css?
Ruleset : Selectors can be attached to other selectors to be identified by ruleset. It has two parts: Selector, e.g. R and declaration {text-indent: 11pt}
What are the items that used as a CSS Selector?
CSS selectors can target HTML elements using various criteria, including element types (e.g., div, p), classes (e.g., .classname), IDs (e.g., #idname), attribute values (e.g., [type="text"]), and pseudo-classes (e.g., :hover). Additionally, combinators like descendant ( ), child (>), and sibling (+, ~) selectors can establish relationships between elements. More advanced selectors also include pseudo-elements (e.g., ::before, ::after) and group selectors (e.g., h1, h2, h3). These selectors allow for precise targeting and styling of elements within a webpage.

In short, no. Quirks mode HTML (no doctype) can be written in any form of casing you want. HTML markup should be written in lowercase as a rule of thumb. XML requires you to use lowercase or errors will be generated.

Yes. There's no way for the browser to know that you intend for an inline CSS style (one using the style attribute of an element) to apply on other objects. Use classes or selectors in the stylesheet to achieve this instead.

Which selectors are used when you want to redefine the general look for an entire HTML tag?
You want to use a tag selector to define the look and feel of all tags of a certain type. These selectors are comprised of the tag itself, in front of the CSS declarations. p {font-weight:bold;} img {width: 245px;} Those will define the properties on all the paragraphs and images in the page.
How do CSS selectors work?
First, you have to define classes or IDs in your html content (for example, the area for your main content gets an id="content"). In your CSS, you can use #content (if it is an ID) or .content (if you specified class="content") to style it. Beware that IDs can be used only once in a HTML document whereas classes can be used multiple times.
