How to set and change the style of images with css

Apr 21, 2023 am 11:24 AM

CSS (Cascading Style Sheets) is a web design language used to add style and layout to web pages. CSS provides a wide range of features, including the ability to add styles to images. In this article, we will learn how to style and change images using CSS.

Step One: Select an Image

Before using CSS to add styles to an image, we need to first make a selection on the image we need to apply it to. We can use different HTML elements to display images, the most common of which is img. We can use the following code in an HTML document to display an image:

<img src=&#39;example.jpg&#39;>
Copy after login

where the src attribute represents the URL of the file we want to use as the source of the image. We can specify the image source using relative or absolute paths. For example, if we wanted to display the example.jpg file located in the root directory of our website, we could use the following code:

<img src=&#39;/example.jpg&#39;>
Copy after login

Now that we have selected the image we want to style, here are the steps on how to style the image.

Step 2: Set the size of the image

To adjust the size of the image, we can use the width and height properties of CSS. For example, if we wanted to set the width of an image to 200 pixels and the height to 150 pixels, we could use the following code:

img {
   width: 200px;
   height: 150px;
}
Copy after login

where img is the selector of the element we want to apply the style to. The width and height attributes represent the width and height of the image we want to set. In this case, the width is set to 200 pixels and the height to 150 pixels.

Step 3: Modify the color of the image

We can use the filter property of CSS to modify the color of the image. The value of the filter attribute is an ordered list of CSS functions, where each function represents the filter type and parameters to be applied. Here are some commonly used filter types:

-grayscale Converts an image to grayscale.
-sepia converts images to sepia tones.
-invert Inverts the colors of the image.
-saturate increases the saturation of the image.
-brightnessAdjust the brightness of the image.
-contrastAdjust the contrast of the image.

For example, if we want to convert the image to grayscale, we can use the following code:

img {
   filter: grayscale(100%);
}
Copy after login

Where, the grayscale(100%) function means to completely convert the image to grayscale. We can use values ​​between 0% and 100% to specify the extent of the effect to be applied.

Step 4: Apply Border

We can use the CSS border property to add a border to the image. The border property includes three sub-properties: border-width, border-style and border-color. The border-width property sets the width of the border, the border-style property sets the style of the border, and the border-color property sets the color of the border.

For example, if we want to set our image border to a solid red line with a border width of 2 pixels, we can use the following code:

img {
   border-width: 2px;
   border-style: solid;
   border-color: red;
}
Copy after login

Where, the border-width attribute sets the border The width, the border-style attribute sets the border style, "solid" means a solid border, the border-color attribute sets the border color, here we choose red.

Step 5: Rotate the image

We can use the CSS transform property to rotate the image. The transform attribute includes a series of functions, including rotate(), scale(), and translate(). The rotate() function can be used to rotate elements.

For example, if we want to rotate our image 45 degrees, we can use the following code:

img {
   transform: rotate(45deg);
}
Copy after login

Where, the rotate(45deg) function means to rotate the image 45 degrees. We can use negative values ​​to rotate the image counterclockwise.

These tips are just part of CSS image styling. Depending on your needs, you can combine multiple CSS properties to achieve the desired final effect. Considering the overall design and feel of your website, you should be consistent in your image style.
