How to control the appearance style of labels with css

CSS (Cascading Style Sheets) is a language used for web page layout and design. CSS controls the look and feel of HTML elements, including text, images, and other multimedia content. In web design, CSS can be used to set the color, font, background, positioning and other attributes of the page to make the web page more beautiful and easy to operate.

In CSS, tags are a very important concept. Tags define the types of elements in HTML documents, such as titles, paragraphs, links, etc. In order to make the web page more hierarchical and readable, we need to use CSS to control the appearance of these tags.

Here are some common HTML tags and examples of controlling their appearance with CSS:

1. h1 tag: used for the main title of the page, usually set to a large font

h1 {
    font-size: 36px;
    color: #333;
}

2. p tag: used for paragraphs, usually set to standard size font and default spacing

p {
    font-size: 16px;
    line-height: 1.4;
    margin: 1em 0;
}

3. a tag: used for links, usually set to underline and blue font

a {
    text-decoration: underline;
    color: #007bff;
}

4. img tag: used to insert pictures, usually set to adaptive size and center alignment

img {
    max-width: 100%;
    height: auto;
    display: block;
    margin: 0 auto;
}

5. ul and li Labels: used for lists, usually set to unordered lists and default spacing

ul {
    list-style-type: none;
    margin: 1em 0;
}

li {
    margin-bottom: 0.5em;
}

6. form, input, and button labels: used for forms, usually set to default styles and spacing

form {
    margin: 1em 0;
}

input,
button {
    padding: 0.5em;
    margin: 0.5em;
}
