Как двигать картинку в html
Для движения изображения в HTML можно использовать свойство CSS "position". Например, чтобы переместить изображение вправо на 20 пикселей, можно использовать следующий код:
В данном примере мы задаем свойство "position" со значением "relative", что позволяет перемещать элемент относительно его начального положения. Затем мы используем свойство "left" со значением "20px", чтобы переместить изображение вправо на 20 пикселей.
Также можно использовать свойство "top" для перемещения изображения вверх или "bottom" для перемещения вниз.
Для анимации рекомендуется использовать свойство transform со значениями translate . Такой подход является более оптимизированным и затрачивает меньше ресурсов, а сама анимация будет выглядеть более плавной.
Например, здесь изображения логотипа будет смещено вправо на величину 100px .
How to Position an Image in CSS?
The image position in CSS can be changed by using CSS properties like object-position property and float property. Object-position property is used to align the position with respect to the x,y coordinates of the image within its container. The float property is used to float an element inside the container toward the left or right side.
Pre-requisite
You should know how to use CSS properties on elements. This article will explain the object-position property and float property with an example that will be easy to understand.
Syntax
1. object-position property: The Syntax of object position property :
position can be a numerical value that specifies the distance from the left of the content box( i.e x axis ) and the distance from the top of the content box (i.e., y-axis). It can also take values like left, right, top, bottom, and initial and inherit them as a string to specify the position.
2. Float property : The Syntax of the float property :
Methods
Method 1: Using object-position Property
object-position property: The object position property is used to position any element within a container to the required position within the container. The < img > element or < video > element are mostly positioned within a container using the object position property.
Syntax
The Syntax for the object position property is
Position can take numerical , specific string values , percentage , length , and edge offsets values . Some values are shown in the examples below.
Example Let's see a simple example of object position property and place the img to the top left of the container.
Output :
Method 2: Using float Property
float property: float property is used to change the image position in CSS to the extreme left or extreme right of the container. Float is used to position an element only horizontally. The Syntax of the float property is as follows:
left: place the element to the extreme left of the container right: place the element to the extreme right of the container inherit: inherits floating property from its parent (div, semantic element, etc.) none: element is displayed at its original position as it is.
Some examples of float properties values are as follows:
Let's take an example in which float property is being used on an actual image :
The output of the above HTML code using the float right property is:

You can easily position an image by using the object-position property. You can also use a bunch of other ways like float-property which will be discussed further in this article.
Methods:
-
: Specify how an image element is positioned with x, y coordinates inside its content box. : Specify how an element should float and place an element on its container’s right or left side.
Method 1: Using object-position Property
Syntax:
Property values:
- position: It takes 2 numerical values corresponding to the distance from the left of the content box (x-axis) and the distance from the top of the content box (y-axis) respectively.
Note:
- We can align elements using the position property with some helper property left | right | top | bottom.
- You can either use string values like right, left, center, and top, or you can use numerical values in pixels like 200px, or 250px.
Example: In this example, we are our 1st method object-position property.
Output:
Syntax:
Note: Elements are floated only horizontally i.e. left or right
Property Value:
- left: Place an element on its container’s right.
- right: Place an element on its container’s left.
- inherit: Element inherits floating property from its parent (div, table etc…) elements.
- none: Element is displayed as it is (Default).
Example: In this example, we are using the above-explained method.
How to position image in the center/middle both vertically and horizontally
There are several ways to do this, and if it needs to work in all browsers (IE7+ and the rest) you need to do different things to make it work in some of the cases.
Use absolute position. This only works if you know the size of the image. Here you set it to position: absolute; left: 50%; top: 50%; margin: -<half height of image> 0 0 -<half width of image> .
Use margin: 0 auto;text-align: center; and line-height/font-size . This is a bit more tricky, since line-height doesn’t work as it should in IE for inline-block elements like images. That’s where the font-size comes in. Basically, you set the line-height of the image container to the same as the container’s height. This will vertically align inline elements, but in IE you need to set the font-size instead to make it work.
In modern browsers that support display: flex you can do it by simply setting the container div to display: flex; align-items: center; justify-content: center;
