  • an animation is performed for the text. It consists of changing the font color and the background color.

In the initial state the paragraph has a black background color and a blue font color. The colors (background, font) change in 5 animation intervals respectively as follows: (white, red) → (yellow, brown) → (light green, dark green) → (aqua, blue) → (fuchsia, black ). The animation lasts 3 seconds and loops alternately infinitely many times.

As our default color for text was blue and its background color was black. In this section we will change the color for text and its background with different colors and these colors will changes every 5 animation intervals respectively. Also, these changes will remain in loop with never ending time. In these 5 animation intervals we will change the color for text and its background like follows;

Animation intervals
Background Color
Text Color
At 1st animation interval.
White
Red
At 2nd animation interval.
Yellow
Brown
At 3rd animation interval.

  • An animation allows you to change the alignment of the last title. The title is initially right aligned with a yellow color shadow and an orange color shadow, font size equal to 150%. The animation allows you to change the alignment in three intervals as follows: right then center then left. The animation lasts 1 second and loops alternately 30 times.

In this section, we will change position of our last text which is heading 3 (h3), the position will change from Right to Center and then Center to Left.

To change this text position, we will use "@keyframes alignChange" which will assist us for changing the text position at specific time interval. The font size sill set to 150%.

In Text graphic, we will give shadow color to text Yellow and Orange. We will set this text position change animation in loop with no end time, means it will continue change the position.
