Using CSS can enable web pages to achieve more style effects and layout methods. One of the important effects is to change the content. Through CSS, we can change the color, size, font, position, shape, etc. of text, pictures and other page elements to add more elements to the web page.

Change the text

1.Change the color

Change the text color, the most commonly used is the color attribute. In CSS, you can insert familiar color names (such as "red", "blue") into the color attribute, or you can use hexadecimal color codes, such as #FF0000 for red.

For example:

p {
color: red;
}

To change the font, you need to use font-family property. In the CSS, you will insert the name of the font you want to use. It is recommended to define common style rules for the font and its alternatives so that different variations of the font can be set up for different parts of the site.

For example:

p {
font-family: "Arial", sans-serif;
}

3. Change the text size

To change the text size, you need to use the font-size attribute. You can use relative sizes, such as "larger", "smaller", or absolute units, such as "px" (pixels).

For example:

p {
font-size: 18px;
}

Change picture

Changing the size of the image usually uses the width and height attributes. You can use relative sizes (such as percentages) and absolute units (such as pixels).

img {
width: 200px;
height: auto;
}

To change the position of the image, you need to use the position attribute. You can use absolute or relative positioning. The image position can be set relative to other elements on the page, or it can be fixed above or below the page.

For example:

img {
position: relative;
left: 50px;
top: 30px;
}

Change Other page elements

body {
background-color: #f0f0f0;
}

To change the border style and size, you need to use the border attribute. You can choose different styles of borders (such as solid, dotted, dotted) and set the width of the border.

div {
border: 1px solid #000;
}

}

Using ID selectors is not inherently bad in CSS, but should be used with caution. 1) ID selector is suitable for unique elements or JavaScript hooks. 2) For general styles, class selectors should be used as they are more flexible and maintainable. By balancing the use of ID and class, a more robust and efficient CSS architecture can be implemented.
