Increasing text size in HTML is a simple yet effective way to improve readability. You can use the font-size property in CSS to achieve this.
To increase text size, you can use a relative unit such as em or rem. For example, setting font-size to 1.5em or 1.2rem will increase the text size by 50% or 20% respectively.
Using relative units is beneficial because it allows the text to scale with the user's browser settings.

Increasing Text Size
Increasing text size in HTML is a breeze, and you've got several options to choose from. Inline CSS allows you to apply styles directly to HTML elements using the style attribute, where you can specify the font-size property with a value like 16px or 1.2em.
To change text size using internal or external CSS, you can use a selector like a class or an ID, and the general syntax is selector { font-size: value; }. For example, you could use a class like .large-text { font-size: 18px; }.
Percents are also scalable like ems, and 100% is equal to the current font size, making them a good choice for mobile development. They do cascade like ems, but that's a topic for another time.

Pixels (Px)
Pixels (Px) can be a challenge when it comes to increasing text size.
Pixels have fixed sizes, which means they don't change on different screens. This can be both good and bad.
One pixel is usually equal to one dot on the screen, making it a precise unit of measurement. This allows web developers to create a "pixel-perfect" rendition of web designs.
However, because pixels are a fixed size, they don't size up or down, which can affect font rendering on different resolution screens.

Font Points
Font points can be a bit tricky to work with, especially when it comes to screen displays. They're based on an inch on a ruler, which is equal to 72 points.
One inch is equal to 72 points, which can cause issues with browser compatibility. This is why points are not recommended for developing websites.
If you do need to use points for a print CSS, it can be a good option to overcome browser issues. This is because points are a unit of measurement used in print.

Em as
Em as a unit of measurement for font size is great for mobile web development because it's scalable. This means it will adjust to different screen sizes, making it perfect for responsive design.
Ems are relative to the font size set in the CSS, and if you don't have one set, 1 em will usually be equal to 16px, which is the default font size in most browsers.
One thing to watch out for with ems is that they cascade, which can make pixel-perfect designs a bit more complicated. For example, if the body font size is set at 16px, and the parent div has a font size of 1.2em, then a paragraph in that div with font-size: 1.2em will end up with a font size that's 1.2 em of the 1.2 em of the 16px font, or roughly 23px.

Using Relative Units
Relative units are perfect for making text size adjustments, and I've found them to be super useful in my own web development projects. Percents are scalable like ems, and 100% is equal to the current font size.
Percents are also good for mobile development because of their scalability. 1.5em is 1.5 times larger, and 150% is 150 percent of the font size.
Ems and percents are particularly good for mobile web development, and they cascade like other units. Percents are a good choice for front end web development.
Specific Use Cases
Increasing text size in HTML can be applied to various use cases, such as making website content more readable for older adults or individuals with visual impairments.
You can use the `font-size` property in CSS to increase the text size, as demonstrated in the example where the text is set to 24 pixels.
For instance, if you're designing a website for a senior citizens' organization, you can use a large font size to make the content more accessible.
The `style` attribute can also be used in HTML to increase the text size, as shown in the example where the text size is set to 36 pixels.
To make a specific paragraph of text larger, you can use the `style` attribute within the paragraph's tags, as illustrated in the example where the paragraph is set to 24 pixels.

Changing Text
To change the text size in HTML, you can use inline CSS, which allows you to apply styles to specific HTML elements directly. This is done using the style attribute, which holds all the styling.
Using the font-size property alongside a value is a great way to change the text size. You can use any of your preferred CSS units, such as em or px.
A perfect syntax for this is to use a value like 16px. You can also use other units like rem or em.
For internal or external CSS styling, you can use a selector, which can be an HTML tag, a class, or an ID. The general syntax is to use the selector followed by the font-size property and a value.
For example, you can use the selector h1 to change the text size of all h1 headings.
