For all the website designing and development aspirants, front-end development is a must to learn part. It mainly starts from HTML and CSS. Both of them are the basic and also really important programming languages to learn in website development because they provide the basic structure to our websites. Not only this, these two languages also decide how our website would look like on browser, and especially CSS plays the most crucial role in it.
Practising in both HTML and CSS is an added advantage for the aspiring website developers. So today we are going learn one important factor in CSS which is called child-selection. Knowing about the child-selection will help in the website front-end development directly.
Understanding CSS Basics
Before we go deep into our article to understand the child-selection concept, let's quickly review the basics related to CSS specially.
Imagine you have a blank canvas in which you have random shapes in random sizes. And, now you have to change them according to your choice.
So as per the given example the canvas here is your html file which is blank and have different divisions as shapes.
Now the part of changing them according to you can be accomplished by CSS. As a website designer, you all must have some understanding of CSS and HTML.
Let's understand the child-selection part in detail from scratch.
The Children selection is really important topic in CSS there are multiple ways to select a
child but there are children in a
which are hard to reach so we are going to learn how to reach those children and select them to give style to them.
1. Descendant Selector (" ")
Think of the descendant selector as finding something in a treasure chest. You don't know exactly where it is, but you know it's inside. In CSS, it looks like this:
This selects all paragraphs (p) inside an element with the class "container" and makes their text blue.
2. Child Selector (>)
Imagine you have a family tree, and you want to specifically choose your siblings, not all the relatives. The child selector helps you do just that:
This selects only the list items (li) that are directly children of a ul (unordered list) and makes their text bold.
3. Adjacent Sibling Selector (+)
Picture a line of students in a classroom. The adjacent sibling selector lets you choose the student sitting right next to you:
This selects the paragraph (p) that comes immediately after an h2 (heading level 2) and makes its text italic.
4. General Sibling Selector (~)
Imagine you have a bunch of toys in a box, and you want to pick more than one without being too specific. The general sibling selector helps you do that:
This selects all paragraphs (p) that are siblings of an h2 (heading level 2) and makes their text red.
Now that we've covered the basics, let's explore how these advanced selectors can be your allies in solving complex layout and styling challenges.
Solving Complex Layout Challenges
1. Responsive Design with Media Queries
Imagine you have a magical pair of glasses that automatically adjust their tint based on the sunlight. Media queries are like those glasses for your website.
This media query says, "When the screen is 600 pixels wide or less, make the background color light blue."
2. :nth-child() Selector
Think of a deck of cards, and you want to style every third card differently. The :nth-child() selector is your card-shuffling friend:
This selects every third list item (li) and gives it a yellow background.
3. :not() Selector
Imagine you have a list of animals, and you want to style all animals except the lions. The :not() selector comes to the rescue:
This selects all list items (li) except those with the class "lion" and makes their text bold.
4. :before and :after Pseudo-elements
Think of a book with fancy decorations at the beginning and end of each chapter. The :before and :after pseudo-elements let you add those decorations to your HTML elements:
This adds quotation marks before and after a blockquote, making it look fancy.
