How to change CSS styles to achieve a beautiful appearance of the website
CSS styles are an important part of website design, through which you can define the layout, colors, fonts and other styles of the website. During the website design process, CSS style adjustments can effectively improve the visual effect of the website and achieve a better user experience. Here are some common CSS style adjustment methods.
1. Adjust the color
Adjusting the color is one of the most basic ways to change the style of the website. The choice of color not only affects the overall visual experience of the website, but also can convey information and emotions. For example, red can represent passion and enthusiasm, while blue can convey a sense of nobility and tranquility. When adjusting colors, you can use RGB, HEX, and HSL color representation.
- RGB mode: a combination of three colors (red, green, blue). Each color is represented by a number between 0-255, for example: rgb(255, 0, 0) represents red.
- HEX mode: Use hexadecimal numbers to represent colors. A color has 6 values, representing red, green and blue respectively. For example, #FF0000 represents red.
- HSL mode: Use hue, saturation and brightness values to represent colors. Hue refers to the name of the color, saturation refers to the depth of the color, and brightness refers to the lightness or darkness of the color. For example: hsl(0, 100%, 50%) means red.
2. Adjust the font
Adjustment of the font can give the website a more attractive and unique appearance. Font selection is very important during the design process. For titles, generally choose a more eye-catching font, while for body text, choose a more readable font. In CSS style rules, fonts can be adjusted through attributes such as font-family, font-size, font-style, font-weight, etc., for example:
font-family: "Microsoft Yahei", Helvetica, Arial, sans-serif; (set font)
font-size: 16px; (set font size)
font-style: italic; (set font style)
3. Adjust the Border
Borders can provide a visual demarcation line for web content, and also tell users the part of the site they can interact with. Different border characteristics can be defined through CSS style rules, for example:
border-width:1px; (set border width)
border-color:#000000; (border color)
border-style:solid; (border style)
4. Adjust the background color and image
Adjustment of the website background can reflect the characteristics and functions of the website and enhance the visual experience. In CSS style rules, the background of the website can be adjusted through the background-color and background-image attributes.
background-color: #FFFFFF; (Set the background color)
background-image: url("background.png"); (Set the background image)
Pass the above Method, you can easily adjust the color, border, font, background and other aspects of the website to achieve a beautiful appearance of the website. However, it should be noted that the use of styles cannot exceed the page loading speed. If the style is too complex, it may affect the page loading speed. Therefore, when adjusting CSS styles, we must adhere to the principle of "simplification" and reduce the use of styles as much as possible to improve the performance and ease of use of the website.
