HTML is HyperText Markup Language and is the standard markup language for documents designed to be displayed online. It is assisted by technologies like Cascading Style Sheets (CSS), which allows you to make nice looking websites.
Advanced HTML refers to features and techniques in HTML that are more complex and may require a deeper understanding of the language. Some advanced features of HTML include:
These are just some examples, and there are other advanced features in HTML that you can use to create interactive and engaging websites.
Many techniques and features can be considered "advanced" when it comes to CSS, and this can depend on the context and the specific use case. Some examples of advanced CSS techniques.
These are just a few examples of advanced CSS techniques, and there are many more that can be used to create complex and exciting designs.
In addition to the above, CSS frameworks and preprocessors like bootstrap, Foundation, etc. can be considered advanced usage of CSS as it makes it easy to develop responsive and mobile-first websites quickly.
It's worth noting that many of these advanced techniques involve a lot of trial and error, as well as a good understanding of the basics of CSS. To become proficient in advanced CSS, it's important to have a solid understanding of the basics and to practice using these techniques in various projects.
There are different types of projects that you can build using advanced HTML. Some examples include:
The possibilities are endless and depend on your skills, creativity, and project requirements.

These are just some examples of what you can do with advanced CSS. With CSS’s continual advancement, the possibilities are endless.
The level of difficulty in learning advanced HTML and CSS can vary depending on your prior experience and familiarity with the basics of HTML and CSS. If you already have a solid foundation in HTML and CSS and are familiar with the basics of web development, then learning advanced techniques will likely be less difficult for you.
Advanced CSS and HTML can be challenging to learn, but it is not necessarily difficult. CSS layout techniques, such as Flexbox and Grid, can take some time to understand and master. Creating complex animations, transforms, and 3D effects can also be challenging. But with proper guidance and resources, you can learn these techniques and improve your skills over time.
CSS Grid is a layout system that allows you to create two-dimensional grid-based layouts using CSS. It gives you more control over the placement and size of elements on a web page, making it easier to create complex, responsive layouts that adapt to different screen sizes and orientations.
With CSS Grid, you can create a grid container and then define grid items that are placed within that container. You can control the size and position of grid items using a set of grid-specific properties, such as grid-template-columns and grid-template-rows. You can also use properties such as grid-column and grid-row to specify the placement of grid items within the grid. Here is an example of a basic CSS Grid layout:
{% code-block language="js" %} grid-container {
display: grid;
grid-template-columns: repeat(3, 1fr);
grid-template-rows: 100px 200px;
{% code-block-end %}
{% code-block language="js" %}
.grid-item {
grid-column: span 2;
grid-row: span 2;
% code-block-end %}
In this example, the grid container is defined using the display: grid property and the grid has three columns and two rows, the size of the column is defined by repeat(3, 1fr) which means, it will have three columns with equal width. We also assign grid-item to span over two columns and two rows.
CSS Grid also allows for more advanced layout techniques, such as creating overlapping grid items and defining areas within the grid. These techniques can be used to create visually engaging and interactive layouts that are not possible with traditional layout techniques.
It's also worth mentioning that CSS Grid works well in conjunction with other layout methods such as Flexbox and the multi-column layout module. They can be used together to create even more powerful and flexible layouts.
Flexbox (short for Flexible Box Layout) is a layout system that allows you to create flexible and responsive layouts using CSS. It gives you more control over the alignment and distribution of elements within a container, making it easier to create flexible, adaptable layouts that respond to different screen sizes and orientations. Flexbox is a one-dimensional layout system, it only works on the main axis (horizontally or vertically), unlike CSS Grid which works on two dimensions.
To create a flexbox layout, you create a flex container and then define flex items that are placed within that container. The container uses the display: flex property, and the child elements use the flex property. Here is an example of a basic Flexbox layout:
{% code-block language="js" %} .flex-container {
display: flex;
}
.flex-item {
flex: 1;
{% code-block-end %}
This creates a flex container and defines that the flex items inside it will take the available space proportionally, this flex value can also be specified in a specific unit, such as px, em, rem,%, or vw.
Flexbox is well suited for creating flexible and responsive one-dimensional layouts, such as navigation bars, lists, and form elements. It's also commonly used in combination with CSS Grid to create two-dimensional layouts.
An inline frame (also known as an "iframe") is an HTML element that allows you to embed another HTML document within the current document. It is useful for displaying content from external sources, such as another website, within a web page. The basic syntax for creating an inline frame is as follows:
{% code-block language="js" %}
<iframe src="URL"></iframe>
{% code-block-end %}
Where "URL" is the address of the web page you want to embed. The iframe element has several attributes that you can use to control the appearance and behavior of the embedded content, such as width and height, frame border, and scrolling.
It's important to note that inline frames can be a security risk because they can be used to load malicious content onto a web page. Additionally, some browsers or devices may have difficulty displaying the content inside an iframe. Therefore, it's important to use iframes only from trusted sources and to properly validate any user input that is used to construct the src attribute to avoid malicious inputs.
To play an audio file on an HTML page, you can use the <audio> element. The <audio> element is a self-contained element that can play audio files directly in the browser without the need for a plug-in. Here is an example of how you can use the <audio> element to play an audio file:
{% code-block language="js" %}
<audio controls>
<source src="audio.mp3" type="audio/mpeg">
<source src="audio.ogg" type="audio/ogg">
Your browser does not support the audio element.
</audio>
{% code-block-end %}
The <source> element is used inside the <audio> element to specify the source of the audio file. The src attribute is always used to specify the URL of the audio file, and the type the attribute is used to specify the MIME type of the file. It's worth noting that different browsers may support different audio formats, like mp3, that's why it's usually a good practice to have multiple sources for the same audio.
Creating responsive images in HTML is a technique for ensuring that images automatically adjust their size and resolution to best fit the screen on which they're being displayed. This is especially important for web pages that are designed to be viewed on a variety of devices, such as smartphones and tablets, with different screen sizes and resolutions. The following is a technique used among several others to create responsive images in HTML
{% code-block language="js" %}
<img src="image.jpg" srcset="image-small.jpg 320w, image-medium.jpg 640w, image-large.jpg 1024w" sizes="(max-width: 320px) 280px, (max-width: 640px) 50vw, 1024px" alt=" responsive image">
{% code-block-end %}

Responsive images are images that automatically adjust their size and resolution based on the size and resolution of the device or browser window viewing them. This can be achieved in CSS using a combination of the img tag, the srcset and sizes attributes and media queries.
The img (image) tag is used to embed an image in an HTML document, and the srcset attribute is used to specify a list of images and their corresponding resolutions. The sizes attribute is used to specify the image size in relation to the containing element.
For example:
{% code-block language="js" %}
<img src="small.jpg"
srcset="medium.jpg 1000w, large.jpg 2000w"
sizes="(max-width: 500px) 100vw, (max-width: 1000px) 50vw, 25vw"
alt=" A responsive image">
{% code-block-end %}
Sass (Syntactically Awesome Style Sheets) is a preprocessor for CSS that adds additional features, such as variables, mixins, and functions, to make writing and maintaining CSS code easier. Sass code is written in a syntax that is similar to CSS, but with some additional features, and it is then "compiled" into regular CSS code that can be interpreted by web browsers.
To convert a CSS file to Sass, you can simply change the file extension from .css to .scss (Sass CSS), and then begin adding Sass-specific syntax to the file. Here is an example of how a simple CSS file would look when converted to Sass:
CSS:
{% code-block language="js" %}
body {
background-color: #fff;
}
h1 {
color: #333;
text-align: center;
{% code-block-end %}
Sass:
{% code-block language="js" %}
$primary-color: #333;
body {
background-color: #fff;
}
h1 {
color: $primary-color;
text-align: center;
{% code-block-end %}
As you can see the difference here is Sass uses variables to store values, which can be reused throughout the code base. The $primary-color variable is defined at the top of the file, and its value is then used for the text color of the h1 elements. Sass also has a very similar syntax for nesting selectors (also known as parent selectors) this way you can avoid repeating the same selectors, which is a common problem in CSS.
When building a design using pure CSS, it means you are not using any additional technologies like JavaScript or frameworks like Bootstrap or Foundation to create the design. You are only using the styling capabilities of CSS to create the layout, positioning, and visual effects of the elements on the page. There are a few key techniques to keep in mind when building a design using pure CSS:
While building a design using pure CSS can be challenging, it can also be gratifying. By mastering these techniques and understanding the underlying concepts, you can create rich, engaging designs that look great on any device or browser. It's important to note that even though you are using pure CSS, it is always recommended to optimize and test your designs to ensure that they look and perform as expected on all different devices, browsers, and screen sizes.
