1. What are the advantages of using CSS?
CSS is a programming language created to make it easier for developers and designers to create page layouts and styling.
CSS can be used to change the appearance of web pages, including their layout and style. It helps them avoid the hassle of writing long lines of code by hand or using complicated tools. The benefits of using CSS lie in the fact that it helps to make a website more responsive, easier to maintain and update, and saves time for designers.
2. What are the differences between CSS3 and CSS?
CSS3 is a set of properties and selectors for styling HTML elements, emphasising marked-up documents semantically. It was designed to improve web accessibility, internationalisation, presentational flexibility, and device independence.
CSS stands for “cascading style sheet”, which is the language that designers use to specify how HTML elements should look. It’s one of the most fundamental parts of good design because it sets every letter colour, every image size, every margin width.
We can see that CSS3 gives us more graphical functionality than CSS does. The critical differences between CSS3 and CSS are that CSS3 is based on the original cascading style sheets (CSS) but has more features.
3. CSS3 introduces some new colour properties. What are they?
CSS3 introduced some new colour properties. These include:
- HSL (https://en.wikipedia.org/wiki/HSL_and_HSLA) — colours are specified by hue, saturation and lightness
- HSLA (https://en.wikipedia.org/wiki/HSL_and_HSLA) — colours are specified by hue, saturation and luminosity
- RGBa (https://en.wikipedia.org/wiki/RGBA) — colours have red, green and blue components with an “a” channel for alpha transparency
- Invert colours with the opacity property
- Transparent color with the rgba() function
- One way to use the HSL() function is to specify a two-digit hexadecimal value
4. How do the animations in CSS3 work?
The animations in CSS3 work by using an animation property and specifying a set of keyframes along with some timing functions to define the behavior of the animation.
There are two ways to specify an animation: as a declaration block or as part of another rule. The first one is used when you want to animate a single property, for example:
- { property: value; }
The second way is used to animate properties that belong to two different elements. For instance, you might have a rule that specifies the width and height of an element — that way. Both properties will be animated at once. In this case, the declaration block looks like this:
- { property1 : value1; property2 : value2;}
5. In CSS3, what new features are available for Text?
When it comes to formatting text in CSS3, a few new features are available.
There is now an option for full justification, adding hyphens and quotation marks. There’s also a command for centring Text, which we haven’t seen before in CSS.
One of the most exciting new features is adjusting the space between letters with CSS3. This will let you control how close notes are to one another and how much space between them.
