HTML Background Color In HTML and CSS, background color is denoted by the background-color property. To add or change background color in HTML, simply add inline CSS to your code. Here’s an example: In the past, you could use the bgcolor attribute to change the background color of a page or element. Say you wanted to change the background color of a web page to maroon. You would have simply added the bgcolor attribute in the opening body tag and set it to the hex color code #800000, as shown below. However, this attribute has been deprecated in the latest version of HTML and replaced by a much better alternative, the CSS background-color property. Using this property, you can add and change background colors on your website. Below, we cover a tutorial in more detail. How to Add Background Color in HTML To add background color in HTML, use the CSS background-color property. Set it to the color name or code you want and place it inside a style attribute. Then add this style attribute to an HTML element, like a table, heading, div, or span tag. Adding a background color can help a certain element stand out on the page, making it more readable. We’ll walk through this process step-by-step. For this tutorial, we’ll make a table in HTML as an example. 1. Identify the HTML element you’d like to add a background to or create one. Scan your HTML code to pinpoint which element you’d like to change. If it’s the header, look for the opening tag. If it’s a div, look for the tag. 2. Choose an HTML background color. You have plenty of HTML color codes to choose from. For this example, we’ll make the color #33475b.

How to Change a Div Background Color A div is a container element that’s commonly used to designate different sections of a webpage. Changing the background color of a div is identical to changing the background color of your web page’s body. Usually, a web page will have many divs. In this tutorial, we’ll teach you how to change one div only. Let’s go through the process step-by-step. 1. Add a CSS class to the div you’d like to change. First, find the div in your HTML code and add a class to the opening tag. Adding a class to an element will allow you to change that element only. Here’s what that looks like: 2. Add the new class selector to your CSS code. Next, head over to your CSS code and add your new class selector. Within the brackets, include the background-color property. Here’s what that looks like: 3. Choose a new background color. Next, choose a CSS background color for your background-color property. We chose rgb(255, 122, 89). Here’s what that code looks like: Here’s the result: All done! You’ve changed the background of a div on your web page. Try It Yourself! The code module below is editable.

How to Add Transparency to Your HTML Background Color When changing background color in HTML, you aren’t limited to solid colors. You can change the opacity and transparency to create interesting visual effects. Adding Transparency Using RGBA You can set an opacity level of your color with the CSS function rgba(). The “a” stands for alpha channel, which represents the level of transparency in a color. This function takes one extra value from 0 to 1, where 0 is completely transparent and 1 is completely opaque. So, if I wanted to use Solaris with 75% transparency, I’d write the following: Try It Yourself! The code module below is editable.

How to Create an HTML Background Color Gradient For even more style options, you can create a gradient background. This is a special type of image that most commonly shows one color gradually changing to another color in a certain direction like top to bottom, left to right, or diagonally. These are known as linear gradients. To create a linear gradient, you have to specify at least two color stops. Let’s look at four quick examples below. Linear Gradient Tutorial — Top to Bottom Say you want your background color to transition from white at the top of the screen to blue at the bottom. Using the body CSS selector, you’ll apply unique style properties to the body of the web page. Here’s what that looks like from beginning to end. Step 1: Find the body selector in your CSS code. Step 2: Your body might already have a background-color property. Delete that. Rather than use the background-color property, you’ll use the background-image property. Step 3: Set the property to “linear-gradient” and specify two color stops in parentheses. Here’s the syntax: Step 4: Next, you want to set the HTML element’s height to 100% to ensure this image takes up the entire screen. All together, here’s the CSS: Here’s the HTML (including the body tags): Linear Gradient This linear gradient starts as white at the top and transitions to orange at the bottom.

First, find the div in your HTML code and add a class to the opening tag. Adding a class to an element will allow you to change that element only. Here’s what that looks like: 2. Add the new class selector to your CSS code. Next, head over to your CSS code and add your new class selector. Within the brackets, include the background-color property. Here’s what that looks like: 3. Choose a new background color. Next, choose a CSS background color for your background-color property. We chose rgb(255, 122, 89). Here’s what that code looks like: Here’s the result: All done! You’ve changed the background of a div on your web page. Try It Yourself! The code module below is editable.

How to Add Transparency to Your HTML Background Color When changing background color in HTML, you aren’t limited to solid colors. You can change the opacity and transparency to create interesting visual effects. Adding Transparency Using RGBA You can set an opacity level of your color with the CSS function rgba(). The “a” stands for alpha channel, which represents the level of transparency in a color. This function takes one extra value from 0 to 1, where 0 is completely transparent and 1 is completely opaque.

How to Create an HTML Background Color Gradient For even more style options, you can create a gradient background. This is a special type of image that most commonly shows one color gradually changing to another color in a certain direction like top to bottom, left to right, or diagonally. These are known as linear gradients. To create a linear gradient, you have to specify at least two color stops. Let’s look at four quick examples below. Linear Gradient Tutorial — Top to Bottom Say you want your background color to transition from white at the top of the screen to blue at the bottom. Using the body CSS selector, you’ll apply unique style properties to the body of the web page. Here’s what that looks like from beginning to end. Step 1: Find the body selector in your CSS code. Step 2: Your body might already have a background-color property. Delete that. Rather than use the background-color property, you’ll use the background-image property. Step 3: Set the property to “linear-gradient” and specify two color stops in parentheses. Here’s the syntax: Step 4: Next, you want to set the HTML element’s height to 100% to ensure this image takes up the entire screen. All together, here’s the CSS: Here’s the HTML (including the body tags): Linear Gradient This linear gradient starts as white at the top and transitions to orange at the bottom.

Проблемы доступности

Важно обеспечить достаточный цветовой контраст между цветом текста и фоном, чтобы люди со слабым зрением могли его прочитать, но при этом должна быть достаточная разница между введённым текстом и текстом placeholder, чтобы пользователь не путал их.

Коэффициент цветового контраста определяется путём сравнения яркости текста placeholder и цветом фона формы ввода. Чтобы соответствовать рекомендациям Web Content Accessibility Guidelines (WCAG), требуется соотношение 4.5:1 для основного текста и 3:1 для более крупного текста, например, заголовков. Крупный текст определяется как 18.66px и больше с жирным начертанием или 24px и больше с обычным начертанием.

HTML Colors

HTML colors are specified with predefined color names, or with RGB, HEX, HSL, RGBA, or HSLA values.

Color Names

In HTML, a color can be specified by using a color name:

Background Color

You can set the background color for HTML elements:

Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat.

How to Add & Change Background Color in HTML

Setting the background color of a web page or an element on the page can enable you to create unique layouts.

Person adding and changing the background color of a website in html

Take the homepage of Delish as an example. The background image of its header section is a colorful soup. To ensure readers can still see the name of the recipe, the background color of the text box is set to white. The effect is striking and easy to read.

HTML Background Color

In HTML and CSS, background color is denoted by the background-color property. To add or change background color in HTML, simply add inline CSS to your code. Here’s an example:

In the past, you could use the bgcolor attribute to change the background color of a page or element.

Say you wanted to change the background color of a web page to maroon. You would have simply added the bgcolor attribute in the opening body tag and set it to the hex color code #800000, as shown below.

However, this attribute has been deprecated in the latest version of HTML and replaced by a much better alternative, the CSS background-color property. Using this property, you can add and change background colors on your website.

Below, we cover a tutorial in more detail.

How to Add Background Color in HTML

To add background color in HTML, use the CSS background-color property. Set it to the color name or code you want and place it inside a style attribute. Then add this style attribute to an HTML element, like a table, heading, div, or span tag.

Adding a background color can help a certain element stand out on the page, making it more readable.

We’ll walk through this process step-by-step. For this tutorial, we’ll make a table in HTML as an example.

1. Identify the HTML element you’d like to add a background to or create one.

Scan your HTML code to pinpoint which element you’d like to change. If it’s the header, look for the opening tag. If it’s a div, look for the tag.

2. Choose an HTML background color.

You have plenty of HTML color codes to choose from. For this example, we’ll make the color #33475b.
