How to modify font style using CSS

CSS is the abbreviation of Cascading Style Sheets. It is a style language for web design that allows web developers to achieve a better user experience by adjusting the appearance and layout of elements. One of the common modifications is font style.

CSS style sheets can change the fonts on the web page in a very simple way, including font size, color, font type, etc. It is very important for web developers and designers to understand how to use the CSS language to change the appearance of text. Below we will focus on how to modify font styles with CSS.

1. Change font type

The first step is to change the font type, which is the most basic operation. Using CSS, you can select a font type in your HTML file, such as "Times New Roman" or "Helvetica" etc. To make font type changes more specific, put them in a CSS style sheet and give them a category, like in the following example:

body {
    font-family: Arial, sans-serif;
}

In this example, font-familyAttribute specifies the font displayed in the document, so all text is displayed in Arial font by default. In this definition, an alternative font is also specified, that is, if the specified font cannot be displayed in the browser, a sans-serif font will be used as an alternative.

2. Change font size

In addition to specifying different font types, CSS can also be used to change font size. Valid CSS code for an element that needs to have its font size changed would look like:

h1 {
    font-size: 32px;
}

In this example, we used the font-size attribute to specify a size of 32 pixels for Heading 1. The font-size property can accept pixels, EM (relative size based on the current font size) and percentage as units. Generally, pixels are a better unit because they provide precise values.

3. Change font color

Font color is one of the important components in web design, and it can be changed using CSS. The following example demonstrates how to change text color using CSS:

p {
    color: #333;
}

In this example, #333 is a hexadecimal character color code that represents gray. To set a different font color, replace #333 with the color code or color name. CSS uses color values ​​to determine color codes.

4. Add other font effects

CSS also supports some special techniques to add other font effects, such as bold, italics, underline and strikethrough, etc. The code is as follows:

h2 {
    font-weight: bold;
    font-style: italic;
    text-decoration: underline;
    text-decoration: line-through;
}

By using the font-weight attribute, you can add a bold effect to the text. The font-style attribute is used to add italics. Use the text-decoration attribute to add an underline or strikethrough effect. In this example, we add underline and strikethrough effects by using the text-decoration attribute.

Summary

By using CSS, you can easily modify the appearance and style of text on a web page. These text styles include font type, font size, color, and other effects such as bold, italics, underline, strikethrough, etc. When designing your website, you should pay attention to maintaining consistency and always use the same font and font size to make the website look neat and professional.
