Create an Animated Scene with HTML and CSS: Adding a Tree and Moving Clouds
Summary
TLDRThis video tutorial demonstrates how to create an animated scene using HTML and CSS, featuring a tree in the foreground and moving clouds in the background. It explains the use of CSS animations to make the tree sway gently and the clouds move slowly. The tutorial covers the structure of the HTML elements and the detailed CSS styling, including the use of pseudo-elements and keyframe animations to achieve the desired effects.

Takeaways
- 🌳 The scene consists of a tree in the foreground and clouds moving in the background, created using HTML and CSS.
- ✨ CSS animations are used to create a gentle swaying effect for the tree and a slow-moving animation for the clouds.
- 📦 The outermost div with the class 'wrap' contains the entire scene, and the inner div with the class 'innerWrap' contains the individual elements.
- 🌌 The 'sky' div represents the background of the scene and is styled with a light blue color and a rounded shape.
- 🌲 The 'tree' div represents the tree in the foreground, with additional styling for the trunk and leaves.
- 🍂 The 'trunk' div, a child of the 'tree' element, uses CSS to create a triangular shape for the tree's trunk.
- 🌄 The 'hill' div represents a hill in the background, styled with a greenish color and rounded top.
- 🎨 The 'wrap' class creates a circular container with a background gradient, centered on the page.
- 🌫️ Pseudo-elements are used to add decorative elements and create effects like the tree's shadow and sky panning.
- 🎥 The keyframes rule defines the animation for the sky, creating a continuous panning effect with changing opacity.
Q & A
What is the purpose of the 'wrap' class in the HTML structure described in the script?
-The 'wrap' class is used as the outermost div element to contain the entire animated scene, ensuring that all parts of the scene are encapsulated within a single container.
What role does the 'inner-app' div element play in the scene construction?
-The 'inner-app' div element is used to contain the individual elements that make up the scene, providing a structure for organizing the tree, hill, and sky elements.
How does the 'sky' class contribute to the background of the scene?
-The 'sky' class is used to create the background of the scene with a light blue color, rounded shape, and a 3D effect through box shadow, and it also includes a continuous panning animation.
What is the function of the 'tree' class in the CSS code?
-The 'tree' class is used to create a tree in the foreground of the scene with a green background color, rounded top, and an upper part with a darker shade of green.
Can you explain the use of the 'trunk' class in the scene?
-The 'trunk' class is used to create the trunk of the tree. It is positioned absolutely and initially set with a height of 0px to be invisible, but it is then styled with border properties to create a triangular brown shape representing the trunk.
What does the 'hill' class represent in the scene and how is it styled?
-The 'hill' class represents a hill in the background of the scene. It is styled with a greenish color, a rounded top, and positioned absolutely at the bottom of the scene. It also has a darker shade at the bottom created by the 'after' pseudo-element.
How is the 'arap' class used to create a circular container for the scene?
-The 'arap' class is used to create a circular container with a background gradient, fixed width and height, and is centered on the page using absolute positioning and the transform property.
What is the purpose of the pseudo-elements '::after' and '::before' in the CSS code?
-The '::after' and '::before' pseudo-elements are used to create decorative elements and additional visual effects, such as the gray circle inside the 'wrap' container and the darker shades for the tree and hill.
What is the keyframe animation 'skyPanning' used for in the script?
-The 'skyPanning' keyframe animation is used to create a slow-moving, continuous panning effect for the sky, starting with an opacity of 0, moving to the right, and then decreasing the opacity to create a loop.
How does the CSS set the position and height of the 'body' element to ensure proper scene positioning?
-The CSS sets the position of the 'body' to 'relative' and its height to 95% of the viewport height, which ensures that the scene is correctly positioned and takes up most of the page's vertical space.
Where can viewers find the source code for the animated scene described in the script?
-Viewers can find the source code for the animated scene on the speaker's GitHub, which is shared in the video description.

Transcripts
we will be creating an animated scene
using HTML and CSS
the scene will feature a tree in the
foreground and clouds moving in the
background
we will use CSS animations to create a
gentle swaying effect for the tree and a
slow-moving animation for the clouds
let's start
the outermost div element with a class
of wrap is used to contain the entire
scene inside the wrapped Ivy there is
another div element with a class of
inner app
this is used to contain the individual
elements that make up the scene that
skydiving represents the background of
the scene
this element has a class of its sky that
tree div represents a tree in the
foreground of the scene
this element has a class of treat that
trunk div is an element that represents
the trunk of the tree
this element has a class of trunk and is
a child of the tree elements that Hill
div is an element that represents a hill
in the background of the scene
this element has a class of pill
this CSS code is used to style a scene
with a tree a hill and a sky
here's a detailed explanation of each
part of the code the first few lines of
CSS set the position of the body to
relative and its height to 95 of the
viewport height
this will ensure that the scene is
positioned correctly on the page
the next line sets the position of the
pseudoelements asterisk after and
asterisk before to Absolute and adds an
empty content property
this is a common technique used in CSS
to create decorative elements
the arap class is used to create a
circular container for the scene
it has a background gradient a fixed
width and height and is positioned in
the center of the page using absolute
positioning and the transform property
the after pseudo element is used to
create a gray circle inside the wrapped
container
the interrupt class is used to contain
the individual elements that make up the
scene
it has a relative position and a fixed
height
the tree class is used to create a tree
in the foreground of the scene
it has a green background color and is
positioned using absolute positioning
the Border radius properties are used to
create a rounded top for the tree
that after pseudo element is used to
create a darker shade of green for the
upper part of the tree
the trunk class is used to create the
trunk of the tree
I dispositioned absolutely and has a
height of 0px which means it will not be
visible
the trunk is created using border
properties to create a triangular shape
with a brown color
that Sky class is used to create the sky
in the background of the scene
it has a light blue background color a
border radius of 100px to create a
rounded shape and a box Shadow to create
a 3d effect
the animation property is used to create
a continuous panning animation for the
sky using that Sky panning keyframes
Beth Hill class is used to create a hill
in the background of the scene
it has a greenish color and is
positioned absolutely at the bottom of
the scene
the Border radius property is used to
create a rounded top for the hill
that after pseudoelement for the hill
class is used to create a darker shade
of green for the bottom part of the Hill
the transform property is used to flip
the shape horizontally
but at keyframes rule is used to define
that Sky panning animation
it starts with an opacity of 0 and a
right position of Dash 250px then
gradually increases the opacity to 1 and
moves the sky to the right and finally
decreases the opacity to zero and moves
the sky to the right again
overall this CSS code creates a visually
appealing scene with a tree a hill and a
sky that I hope this explanation helps
