sibling selector css code example

Example 1: css select all siblings after element

/*To match to any sibling element after the selector on the left,
  use the tilde symbol '~'. This is called the general sibling combinator. */

h1 ~ p {
  color: black;
}

Example 2: adjacent sibling selector

/*The adjacent sibling combinator (+) separates two 
selectors and matches the second element only if 
it immediately follows the first element, and
both are children of the same parent element.*/

li:first-of-type + li {
  color: red;
}

<ul>
  <li>One</li> // The sibling 
  <li>Two</li> // This adjacent sibling will be red
  <li>Three</li>
</ul>

Example 3: css select sibling

/*
Adjecent Sibling Selector
-------------------------
example: Select all <p> tags that immediatly follows after <div> tag
*/
div + p {
  background-color: yellow;
}

/*
General Sibling Selector
-------------------------
example: Select all <p> tags that has a sibling with a <div> tag
*/
div ~ p {
  background-color: yellow;
}

Example 4: 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 5: sibling selector css

/*General Sibling*/
/*The general sibling selector selects all elements that are siblings of a specified element.
The following example selects all <p> elements that are siblings of <div> elements: */
/*<div></div>
  <p></p>*/
div ~ p{
}

/*Adjacent Sibling*/
/*The adjacent sibling selector is used to select an element that is directly after another specific element.
Sibling elements must have the same parent element, and "adjacent" means "immediately following".
The following example selects the first <p> element that are placed immediately after <div> elements*/
/*<div><p></p></div>
  */
div + p{
}

Example 6: css selector for sibling element

/* Paragraphs that come immediately after any image */
img + p {
  font-weight: bold;
}
