Step diagram CSS

Step diagram is a common graphical tool that explains a process or operation process through a series of simple step instructions. Step diagrams usually use geometric figures marked with numbers, text, or arrows to clearly illustrate the operation process. In web design and development, step diagrams are often used in tutorials, guides, product description pages, etc.

CSS technology has made the design of step diagrams simpler, faster, and more beautiful. With some simple CSS codes, you can create clear, beautiful step diagrams.

1. Create a step diagram frame

First, we need to create a step diagram frame, that is, a container that contains a series of step tiles. You can create this frame using HTML and CSS.

<div class="steps-container">
    <div class="step">
        <span class="step-number">1</span>
        <p class="step-description">步骤1</p>
    </div>
    <div class="step">
        <span class="step-number">2</span>
        <p class="step-description">步骤2</p>
    </div>
    <div class="step">
        <span class="step-number">3</span>
        <p class="step-description">步骤3</p>
    </div>
</div>

In the above code, we first create a step diagram container (.steps-container), and then add three step tiles (.step) to it. Each step tile includes a step number (.step-number) and a step description (.step-description).

2. Design step block styles

Now, we need to add styles to each step block. Here we will use CSS syntax to add styles such as borders, backgrounds, shadows, and rounded corners to each step tile.

.step {
    border: 2px solid #999;
    border-radius: 6px;
    background-color: #fff;
    box-shadow: rgba(0, 0, 0, 0.3) 0 0 5px;
    display: flex;
    align-items: center;
    justify-content: center;
    padding: 20px;
    margin-bottom: 20px;
    position: relative;
}

In the code, we add a 2-pixel wide solid border to each step tile, and use border-radius to add 6-pixel rounded corners to the tile. The background color was set to white and a light gray shadow was added to the step block using the box-shadow property.

In order to make the step number and step instructions more centered and beautiful, we use properties such as display and align-items to center the step tiles and add an appropriate amount of spacing and padding.

3. Add styles to the step number

Using CSS, we can add styles to the step number (.step-number) very simply. The following code can be used to set the size, color and font style of the step number:

.step-number {
    display: block;
    width: 30px;
    height: 30px;
    border-radius: 50%;
    background-color: #999;
    color: #fff;
    font-size: 14px;
    line-height: 30px;
    text-align: center;
}

The above code will add a circle style (border-radius: 50%) to the step number (.step-number) and set Its size (attributes such as width and height), background color (background-color) and text color (color). To center the step number, we use the text-align and line-height properties.

4. Add connections between step tiles

With some simple CSS code, we can create arrows, connections and other styles of lines between step tiles. The following code creates an arrow style for step blocks:

.step:before {
    content: "";
    position: absolute;
    top: -20px;
    left: 50%;
    width: 0;
    height: 0;
    border-style: solid;
    border-width: 20px 15px 0 15px;
    border-color: #999 transparent transparent transparent;
    transform: translateX(-50%);
}

This code block adds a pseudo-element before each step block (.step) to create arrows between step blocks ( :before). We use the position property to align the arrows above each step tile, and use the -transform and left properties to center the arrows horizontally.

By modifying the style properties in the code block above, you can also create straight, dotted, and rounded style connections between step blocks.

With the above simple CSS techniques, you can quickly create beautiful and detailed step diagram effects, improving the visual effects and ease of use of pages such as tutorials, guides, and product descriptions.
