Just asked DeepSeek a question:

_Hi, what's the best way to vertically center some text on a Web page?_

DeepSeek's answer was pretty solid:

Vertically centering text on a web page can be achieved in several ways, depending on the context and the layout method you're using. Here are some of the most common and effective techniques:

### 1. **Using Flexbox**
Flexbox is one of the easiest and most flexible ways to center content both vertically and horizontally.

```html
<div style="display: flex; justify-content: center; align-items: center; height: 100vh;">
  <p>Centered Text</p>
</div>
```

- `display: flex;` enables Flexbox.
- `justify-content: center;` centers the content horizontally.
- `align-items: center;` centers the content vertically.
- `height: 100vh;` makes the container take up the full viewport height.

### 2. **Using Grid**
CSS Grid is another powerful layout system that can easily center content.

```html
<div style="display: grid; place-items: center; height: 100vh;">
  <p>Centered Text</p>
</div>
```

- `display: grid;` enables Grid.
- `place-items: center;` centers the content both vertically and horizontally.
- `height: 100vh;` makes the container take up the full viewport height.

### 3. **Using Absolute Positioning and Transform**
This method is useful when you need to center an element within a parent container.

```html
<div style="position: relative; height: 100vh;">
  <p style="position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%);">Centered Text</p>
</div>
```

- `position: relative;` on the parent container.
- `position: absolute;` on the child element.
- `top: 50%; left: 50%;` moves the element to the center of the container.
- `transform: translate(-50%, -50%);` adjusts the element's position to truly center it.

### 4. **Using Table Display**
This method uses CSS table properties to center content.

```html
<div style="display: table; width: 100%; height: 100vh;">
  <div style="display: table-cell; vertical-align: middle; text-align: center;">
    <p>Centered Text</p>
  </div>
</div>
```

- `display: table;` on the parent container.
- `display: table-cell;` on the child container.
- `vertical-align: middle;` centers the content vertically.
- `text-align: center;` centers the content horizontally.

### 5. **Using Line Height (for single lines of text)**
If you have a single line of text and a fixed height, you can use the `line-height` property.

```html
<div style="height: 100px; line-height: 100px; text-align: center;">
  <p>Centered Text</p>
</div>
```

- `height: 100px;` sets the height of the container.
- `line-height: 100px;` makes the line height equal to the container height, centering the text vertically.
- `text-align: center;` centers the text horizontally.

### 6. **Using Padding**
If you know the height of the container, you can use padding to center the text.

```html
<div style="padding: 50px 0; text-align: center;">
  <p>Centered Text</p>
</div>
```

- `padding: 50px 0;` adds equal padding to the top and bottom, centering the text vertically.
- `text-align: center;` centers the text horizontally.

### Conclusion
- **Flexbox** and **Grid** are the most modern and flexible solutions.
- **Absolute positioning** is useful for specific cases where you need to center within a parent container.
- **Table display** and **line-height** are older methods but still useful in certain scenarios.
