Text sizing is a crucial aspect of responsive web design, and CSS provides several ways to control it. CSS font size can be set using the font-size property, which can be specified in various units such as pixels (px), ems (em), or percentages (%).
Setting the font size to 16px in pixels is a common default value for desktop browsers. This size is often used as a baseline for other font sizes on the page. The font size can also be set to 1em, which is equivalent to the current font size.
To make text more readable on smaller screens, it's a good idea to set a minimum font size, such as 12px or 14px. This ensures that text remains legible even on devices with smaller screens.

Text Sizing Units
Points are a unit of measurement used in print, based on an inch on a ruler, and one inch is equal to 72 points.
Points are very good for setting up a print CSS to overcome browser issues, but they vary greatly between different browsers and screens when used in CSS.
Pixels, em units, and rem units are the most common length values you can assign to the font-size property.

Pixels (Px)
Pixels (Px) are a fixed size, usually equal to one dot on the screen.
Using pixels as your length lets you set font size with precision, regardless of the browser a visitor is using. It specifies exactly the number of pixels in height that you want a browser to render your text.
One pixel is a fixed size, which can be a good thing for making pixel-perfect renditions of web designs, but it's also a drawback because fonts will be rendered smaller on a screen with higher resolution than on a lower resolution screen.
Pixels aren't optimized for all devices, and they're not an accessible length value.
Points (pt)
Points are a unit of measurement used in print, based on an inch on a ruler, with one inch equal to 72 points.
Points are very good for setting up a print CSS to overcome browser issues, but they're not recommended for developing websites due to their variability between different browsers and screens.
One inch is equal to 72 points, a fact that's useful to keep in mind when working with points in print design.
Relative Text Sizing
Relative text sizing is a great way to set font sizes, especially when you want them to change relative to their parent elements. This makes it easy to create a hierarchy of text sizes on your website.
Relative-size keywords, such as smaller, can make text look larger or smaller compared to the parent element's font size. For example, if a parent element has a font-size of large, a child element with a font-size of smaller will look like it's font size were medium.
Percents are also scalable like ems, and 100% is equal to the current font size. Think of it this way: 1.5em is 1.5 times larger, and 150% is 150 percent of the font size.
Percentage values set the font size of an element relative to the parent element's font size. This means you can make text larger or smaller depending on the percentage value you choose.
Using relative text sizing has its advantages, especially for accessibility. It allows users to change the text size in all browsers, making it a good choice for creating websites that are user-friendly for everyone.

HTML and CSS
HTML and CSS are two fundamental technologies used in web development. HTML stands for HyperText Markup Language and is used to create the structure and content of a web page.
You can use CSS, or Cascading Style Sheets, to control the layout and visual styling of a web page. CSS is what makes a website visually appealing.
HTML and CSS work together to create a visually appealing and user-friendly website.
Baseline Widely Available
HTML and CSS have come a long way since their inception.
HTML5 is the most widely supported version of HTML, and it's the default version used by most web browsers.
The baseline for HTML and CSS is HTML5, which is supported by all major browsers, including Google Chrome, Mozilla Firefox, and Apple Safari.
The latest versions of these browsers have dropped support for older versions of HTML, making HTML5 the de facto standard.
HTML5 introduces new semantic elements like header, nav, and footer, which make it easier to structure and organize content.
These new elements provide a clear visual hierarchy and improve accessibility for users with disabilities.
The CSS baseline is CSS3, which provides a robust set of styling options and layout controls.
CSS3 introduces new features like media queries, which allow for responsive design and flexible layouts.
Media queries enable developers to create layouts that adapt to different screen sizes and devices, making websites more user-friendly and accessible.
Html
HTML is a fundamental language for building websites and web applications. It stands for HyperText Markup Language and is used to define the structure and content of web pages.
To change the font size of HTML text, you can use CSS syntax, which involves specifying the selector, font-size property, and custom value with preferred units.
You can select an HTML element, such as a heading or paragraph, using a class, tag, or id. In the example, a paragraph element is selected to change its font size.
The font-size property is used to set a custom value, and pixels (px) are used as the units in the example.
Inline CSS can also be used to change the size of HTML text, but it's generally not advised in large projects.

Styling Text with Color
You can use the color property to change the color of text in HTML. For example, in the article section "Basic Text Styles", we used the style attribute to set the color of a paragraph to blue.
To apply a color to text, you can use a color name, a hex code, or a color function. In the section "Basic Text Styles", we used the color name "blue" to change the text color.
The color property can also be used to set the background color of text. In the article section "Basic Text Styles", we used the background-color property to set the background color of a paragraph to yellow.
You can also use the color property to set the color of a specific text element, such as a heading or a link. In the section "Link Styles", we used the color property to change the color of a link to red.
The color property can be used in combination with other properties, such as font-size and font-family, to create a specific text style.

Text Sizing Properties
The default font size in HTML is 16 pixels.
Absolute-size keywords are based on the default font size, which is medium, equivalent to 16 pixels or 1 em.
These keywords are: xx-small, x-small, small, medium, large, x-large, xx-large, and xxx-large.
You can use these keywords to set text to a specified size and create a font hierarchy for your page.
Absolute-size keywords do not allow a user to change the text size in all browsers, making them a poor choice for accessibility.
Instead, consider using relative-size keywords for a more inclusive approach.

Responsive
Responsive text sizing is a game-changer for websites that need to adapt to different screen sizes.
The vw unit is a relative unit that's based on the width of the viewport, not a parent element or root element. 1 vw equals 1% of the viewport, so if the viewport is 100 pixels wide, 1vw equals 1 pixel.
To set a font size that's 10% of the browser window's width, use the code vw unit. The code looks like this: font-size: 10vw.
Resizing the viewport shows the text adapting to the new size.
Max
Max is a popular font in the world of typography, and it's often used in digital design. It's a clean and modern sans-serif font that works well for body text.
Max is particularly well-suited for digital screens because of its clear and legible design. This makes it a great choice for web design, where text is often displayed on small screens.
One of the key benefits of using Max is its scalability, meaning it looks good in a variety of font sizes. This is thanks to its well-designed font metrics, which ensure that the text remains readable even at small sizes.
In terms of font sizing, Max is often used in conjunction with CSS to create a consistent look and feel across a website. By setting the font size to 16px, for example, you can ensure that the text is easy to read on a variety of devices.
