Learn these absolute positioning techniques to make your web design more professional!

In the modern network environment, web design is becoming more and more important. A good web design not only improves the user experience, but also improves the usability and accessibility of the website. In web design, absolute positioning is a very important technique. Through absolute positioning, we can precisely control the position of web elements on the page. This article will introduce some absolute positioning techniques and provide specific code examples.

1. Using the position attribute

In CSS, you can use the position attribute to specify the positioning method of an element. The position attribute has several optional values, the most commonly used ones are absolute and relative.

• absolute: Use absolute positioning. The element's position will be positioned relative to its nearest parent element that has a positioning attribute (non-static). If there is no parent element with a positioned attribute, it is positioned relative to the browser window.
• relative: Use relative positioning. The element's position will be positioned relative to its original position in the document. The position of the parent element will not change.

Sample code:

#element {
  position: absolute;
  top: 100px;
  left: 200px;
}

#container {
  position: relative;
}

2. Set top, right, bottom, left attributes

In absolute positioning, you can use top, right , bottom and left attributes to specify the position of the element relative to the parent element. These properties accept a numeric value (such as px, em, etc.) or a percentage value.

Sample code:

#element {
  position: absolute;
  top: 100px;
  right: 200px;
}

#element2 {
  position: absolute;
  bottom: 50%;
  left: 20%;
}

3. Use the z-index attribute

The z-index attribute can control the stacking order of elements in the vertical direction. Elements with a higher stacking order will overlay elements with a lower stacking order. The value of z-index must be an integer.

Sample code:

#element1 {
  position: absolute;
  top: 100px;
  left: 200px;
  z-index: 2;
}

#element2 {
  position: absolute;
  top: 150px;
  left: 250px;
  z-index: 1;
}

4. Combined with other positioning techniques

Absolute positioning can be used in conjunction with other positioning techniques, such as relative positioning, fixed positioning, and sticky position.

Sample code:

#element1 {
  position: relative;
  top: 50px;
  left: 50px;
}

#element2 {
  position: fixed;
  top: 100px;
  right: 100px;
}

#element3 {
  position: sticky;
  top: 200px;
}

By learning these absolute positioning techniques, your web design will be more professional. You have more control over the placement of elements on the page, improving user experience and website accessibility.
