select desendant of element code example

Example 1: descendent selector in css

The descendant combinator — typically represented by a single space ( ) 
character — combines two selectors such that elements matched by the second
selector are selected if they have an ancestor 
(parent, parent's parent, parent's parent's parent, etc) 
element matching the first selector. 

example: 
  h1 ul {
    border : 1px solid #f1f1f1;
}
Explanation: This above CSS code snippet will select all the 'ul' (unordered list)
			 tags which are preceeded by an 'h1' (header tag).
/*the best way to understand is to practice by implemetation.
Create a html file with lots of h1 and ul elements to understand by
implementing CSS on them*/

Example 2: CSS descendant selectors

/*Descendant Selectors*/
/*Creates matching patterns based on the relationship between nested elements*/

<section>
	<a href="#"></a> -->/*to select "a" tag in CSS use */--> section a{...}   
</section>

.class-selector-name 
.nested-class-name {...}

---tag with class="class-selector-name"
	|
	|--tag with class="nested-class-name"  <-- Selected

main h1 {...}

---main
	|--h1  <-- Selected
---h1 <-- Not selected!!!
