WDS57 - CSS Pseudo-Elements

In the last two article, we learned about pseudo-classes in CSS and also done some interesting examples to practice it. Hope you have checked the link given in the last article, where we get a complete list of pseudo-classes in CSS. It is very easy to learn them when you know what the concept is used in it.
Moving forward, today it's time for pseudo-elements. Let's begin...

Pseudo...again

Just like the pseudo-classes, pseudo-elements are used to style specified parts of an element. They can be useful in styling particular letter of text or insert content after some specified character using CSS.

Syntax

The syntax for pseudo-elements is similar to that of pseudo-classes:

 selector:: pseudo-element {
    property: value;
}

 Note: We used single-colon for pseudo-classes while double-colon for pseudo-elements.

The ::first-line Pseudo-element

As the name suggests, ::first-line pseudo-element is used to select first-line of any text. It is important to note that, first line here is not the line which is ended by full-stop but the one which will cover one horizontal line on the browser. So it will change as user resize the browser. If you want just specified part as the first line, use <br> that is break element after it, so that your desired part will only be the first line.
Following properties are available for ::first-line pseudo-element:
  • All color properties including background-color
  • All font properties
  • word-spacing, letter-spacing, line-height
  • text-transform, text-decoration
  • vertical-align
  • clear
Let's see one example...

The ::first-letter Pseudo-element

Selects the first letter of a text..here is syntax...
p::first-letter {
    color: #00FF00;
    font-size: 1.5em;
}

Following properties are available for ::first-letter pseudo-element:
  • All color properties including background-color
  • All font properties
  • margin, padding, border
  • text-transform, text-decoration
  • vertical-align
  • clear, float
That's all for today. Today we learned the basics of pseudo-elements in CSS. In the next article, we will combine more than one pseudo-elements and also learn to use them with pseudo-classes.
Till then #keepCoding.

Hello reader, this is my first post on this blog. I created this blog for various purposes including First and most importantly improve my coding Help others to learn various concepts in programming  To complete my hobby of blogging So, I am starting various series simultaneously, hope I will able to continue them. In this " Python Project " series, I will create simple python projects and will give step by step procedure to do that.

WDS85 - Animate the CSS(Part 3)

In the last two articles, we learned about animations in CSS and various ways to customize them with the help of iterations and animation delays. Now in today's article, we are going to learn more about them so that to customize them even more. Let's begin... Reverse Directions and Alternate Cycles The animation-direction property in CSS decides whether we want to play animation forward, backward or in alternate cycles. Following values are possible: normal - This is the default. Animation plays as normal(forward). reverse - The animation plays in reverse direction that is backward. alternate - The animation first plays forward and then backward. alternate-reverse - The animation first plays backward and then forward. Speed Curve of Animation Just like we used various ways to customize transitions in CSS some articles before, same functions can be used to change the speed of the animation. The animation-timing-function property specifies the speed curve o

WDS83 - Animate the CSS

In the last two articles, we learned about CSS transitions and created some pretty cool elements with transitions and transformations. Now in today's class, we are going to learn animations in CSS which creates animations without the use of javascript or flash. CSS Animations A CSS animation lets us change an element's style from one to another. We can change as many properties as we want. To use this CSS animations, we have to first specify some keyframe rules which include how and which properties are we changing. The @keyframes Rule When we specify CSS styles inside the  @keyframes rule, the animations will gradually change from current style to new style at certain times. To get these working, we must bind animations to an element. Let's understand more by an example... @keyframes myAnimation { from { background-color : blue ;} to { background-color : red ;} } div { width : 100px ; height : 100px ; background-color : b
