HTML Font Size – How to Change Text Size with an HTML Tag
Joel Olawanle
When you add text to your HTML file with an HTML tag, you won’t always want the text to remain the default size. You’ll want to be able to adjust how the text displays in the browser.
In this article, you will learn how to change the text size with an HTML tag.
Before you proceed, it is essential to know that there is only one way we can do this: through CSS’s font-size property. We can use the font-size property through inline, internal, or external styling.
In the past, we could adjust text size within our HTML tag without using CSS. But that was before HTML5. Then we added text using the <font> tag, which can take in an attribute of size as seen below:
This size attribute can take in value from 1-7 in which the text size increases from 1 to 7. But like I said, this has long been depreciated, and most people don’t even know it existed.
In case you are in a rush to see how you can change the size of your text, then here it is:
Suppose you are not in a rush. Let’s briefly dive right in.
How to Change Text Size With Inline CSS
Inline CSS allows you to apply styles to specific HTML elements. This means we are putting CSS into an HTML tag directly. We use the style attribute, which now holds all our styling.
We use the font-size property alongside our value to change the text size using inline CSS. This value can use any of your preferred CSS units such as em, px, rem, and so on.
A perfect syntax would be:
How to Change Text Size With Internal or External CSS
The approach you use to change text size in internal and external CSS styling is similar, since you use a selector. The general syntax for this is:
The selector can either be our HTML tag or maybe a class or an ID. For example:
Or we could use a class:
Wrapping Up
In this article, you learned how to change the font/text size of an HTML element using CSS. You also saw how developers did it before the introduction of HTML5.
Also, keep in mind that it’s always better to style your HTML elements using internal or external styling, as it offers a lot of flexibility compared to inline styling.
For example, you can make use of one CSS class for all your p tags rather than having to add inline styles to all your p tag elements.
Using inline styles is not considered best practice because it results in a lot of repetition – you cannot reuse the styles elsewhere. To learn more, you can read my article on Inline Style in HTML.
I hope this tutorial gives you the knowledge to change the size of your HTML text so you can make it look better.
Как сделать больше текст в html
The HTML <font> size Attribute is used to specify the size of text which is present inside <font> element.
Syntax:
Attribute Values: It contains a single value number that specifies the size of the text. The font size lies between 1 to 7. The default value of font size is 3.
Note: The <font> size attribute is not supported by HTML 5.
Example 1: This example illustrates the use of the font size property whose value ranges from 1 to 7 in HTML.
font-size
The font-size CSS property sets the size of the font. Changing the font size also updates the sizes of the font size-relative <length> units, such as em , ex , and so forth.
Try it
Syntax
The font-size property is specified in one of the following ways:
- As one of the absolute-size, relative-size or math keywords
- As a <length> or a <percentage> , relative to the element’s font size.
Values
Absolute-size keywords, based on the user’s default font size (which is medium ).
Relative-size keywords. The font will be larger or smaller relative to the parent element’s font size, roughly by the ratio used to separate the absolute-size keywords above.
A positive <length> value. For most font-relative units (such as em and ex ), the font size is relative to the parent element’s font size.
For font-relative units that are root-based (such as rem ), the font size is relative to the size of the font used by the <html> (root) element.
A positive <percentage> value, relative to the parent element’s font size.
Note: To maximize accessibility, it is generally best to use values that are relative to the user’s default font size.
- math Experimental Special mathematical scaling rules must be applied when determining the computed value of the font-size property.
Description
There are several ways to specify the font size, including keywords or numerical values for pixels or ems. Choose the appropriate method based on the needs of the particular web page.
Keywords
Keywords are a good way to set the size of fonts on the web. By setting a keyword font size on the <body> element, you can set relative font-sizing everywhere else on the page, giving you the ability to easily scale the font up or down on the entire page accordingly.
Pixels
Setting the font size in pixel values ( px ) is a good choice when you need pixel accuracy. A px value is static. This is an OS-independent and cross-browser way of literally telling the browsers to render the letters at exactly the number of pixels in height that you specified. The results may vary slightly across browsers, as they may use different algorithms to achieve a similar effect.
Font sizing settings can also be used in combination. For example, if a parent element is set to 16px and its child element is set to larger , the child element displays larger than the parent element on the page.
Note: Defining font sizes in px is not accessible, because the user cannot change the font size in some browsers. For example, users with limited vision may wish to set the font size much larger than the size chosen by a web designer. Avoid using them for font sizes if you wish to create an inclusive design.
Using an em value creates a dynamic or computed font size (historically the em unit was derived from the width of a capital «M» in a given typeface.). The numeric value acts as a multiplier of the font-size property of the element on which it is used. Consider this example:
In this case, the font size of <p> elements will be double the computed font-size inherited by <p> elements. By extension, a font-size of 1em equals the computed font-size of the element on which it is used.
If a font-size has not been set on any of the <p> ‘s ancestors, then 1em will equal the default browser font-size , which is usually 16px . So, by default 1em is equivalent to 16px , and 2em is equivalent to 32px . If you were to set a font-size of 20px on the <body> element say, then 1em on the <p> elements would instead be equivalent to 20px , and 2em would be equivalent to 40px .
In order to calculate the em equivalent for any pixel value required, you can use this formula:
For example, suppose the font-size of the <body> of the page is set to 16px . If the font-size you want is 12px , then you should specify 0.75em (because 12/16 = 0.75). Similarly, if you want a font size of 10px , then specify 0.625em (10/16 = 0.625); for 22px , specify 1.375em (22/16).
The em is a very useful unit in CSS since it automatically adapts its length relative to the font that the reader chooses to use.
One important fact to keep in mind: em values compound. Take the following HTML and CSS:
Assuming that the browser’s default font-size is 16px, the words «outer» would be rendered at 25.6px, but the word «inner» would be rendered at 40.96px. This is because the inner <span> ‘s font-size is 1.6em which is relative to its parent’s font-size , which is in turn relative to its parent’s font-size . This is often called compounding.
rem values were invented in order to sidestep the compounding problem. rem values are relative to the root html element, not the parent element. In other words, it lets you specify a font size in a relative fashion without being affected by the size of the parent, thereby eliminating compounding.
The CSS below is nearly identical to the previous example. The only exception is that the unit has been changed to rem .
Then we apply this CSS to the same HTML, which looks like this:
In this example, the words «outer inner outer» are all displayed at 25.6px (assuming that the browser’s font-size has been left at the default value of 16px).
Like the em unit, an element’s font-size set using the ex unit is computed or dynamic. It behaves in exactly the same way, except that when setting the font-size property using ex units, the font-size equals the x-height of the first available font used on the page. The number value multiplies the element’s inherited font-size and the font-size compounds relatively.
See the W3C Editor’s Draft for a more detailed description of font-relative length units such as ex .
Тег <big> HTML текст большего размера
Тег <big> используется в HTML коде для написания текста увеличенным размером шрифта (вывод текста большего размера). Использование тега <big> увеличивает размер шрифта текста, который находится внутри тега.
Размер шрифта внутри HTML тега big определяется размером шрифта родительского элемента. При использовании семиуровневой системы размеров шрифтов HTML: от 1 (самый мелкий шрифт) до 7 (самый большой), размер текста внутри тега <big> будет увеличен на единицу.
Тег big может быть вложен в другой тег big . При использовании вложенных тегов <big> размер шрифта будет увеличиваться на единицу с каждым уровнем вложенности.
Поддержка тега big в HTML5
Тег <big> является устаревшим и не поддерживается в HTML5. Используйте CSS свойство font-size вместо него.
