How to Add Background Color in HTML

tag.In this example, we're creating a table with 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.

3. Add a style attribute to the opening tag.

Next, add the style attribute to the opening tag of your element. For this tutorial, only the background color of this specific table will change. The change will not affect any other element on the page.

Here's the HTML with inline CSS:

That's simple. Now let's look at what to do if you want to set the background color of multiple elements on a page.

How to Change Background Color in HTML

Let's say you set the background color of your entire web page to one color and want to change the background color of a specific element to another color. The good news is the process for changing the background color of an element is nearly identical to the process for adding it.

You can use inline CSS to do this, but we'll use multiple styles of CSS in the example below. Let's walk through this process step-by-step.

1. Find the "body" CSS selector.

Rather than add this CSS in the body tag of the HTML file, we'll add it using the bodyCSS selector. Find it in your website's CSS code.

2. Change the background color of the body.

Next, we'll change the background color of the entire web page using the background-color property.

Here's the CSS:

If this was the only CSS, then everything on the page would have the same light blue background. Next, we'll add inline CSS to change the background color of the table.

3. Add inline CSS to change the background color of specific elements.

If we want to change the background color of the table, we can use inline CSS to target that single element.

Here's the opening tag with inline CSS:

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.

Background Color HTML Codes

In this post, we've been using color codes (more specifically, hex color codes) to add colors to the backgrounds of our page elements. But, there are actually a few ways to specify your background colors. Next, let's review the different ways you can write colors in CSS.

Background Color Hex Codes

Hex codes are the most popular format for adding color to page elements in HTML. A hex code is a hexadecimal (base 16) number preceded by a hash symbol (#).

Every hex code contains six characters, and each pair of characters determines the intensity of the three primary colors (red, green, and blue in that order) from 00 (lowest intensity) to FF (highest intensity).

For example, the color white is the highest intensity of all three colors, so its hex code is #FFFFFF. Black is the opposite - the lowest intensity of all colors, or #000000. For the color green, we crank up the intensity for green and lower it for red and blue, giving us the hex code #00FF00. HubSpot's signature shade of orange, Solaris, has the hex code #FF5C35.

If you do the math, this comes out to 16,777,216 possible hex codes. Fortunately, you don't need to guess which color works best for your background. You can use an HTML color picker like this one to select a color from a spectrum, then simply copy the hex code it gives you.

Background Color Names

Hex values aren't too difficult to understand, but there's an even simpler way to add color in HTML: simply use the name of a color.

Modern browsers support 140 standardized HTML color names, including simple ones like Red, Green, Blue, Yellow, Orange, etc. There are also more precise hues like DarkRed, SpringGreen, SkyBlue, Khaki, and Coral.

Check out a color reference like this one for a list of all HTML color names and their corresponding hex and RGB codes. When you find a color value you like, use it as the value of your background-color property (no # symbol necessary).

Background Color RGB Codes

We can also create HTML color values with RGB (red green blue) notation. Like hex codes, RGB values allow us to target a color value by specifying its red, green, and blue intensity.

To add color with RGB, we use the rgb() CSS function. This function takes three values inside the parentheses, each specifying the intensity of red, green, and blue in the color. Each value is a number from 0 to 255, with 0 being the least intense and 255 being the most intense.

For example, the RGB function for Solaris orange in CSS is rgb(255, 92, 53):

HTML color pickers will also provide RGB values along with hex codes, so this is the easiest way to find the RGB code you need. There are also plenty of hex-to-RGB converters online, like this one.

Background color HSL Values

Finally, you can use HSL values to set your colors in CSS. HSL, which stands for hue, saturation, and lightness, is written with the hsl() function. The syntax is similar to RGB, except you use percentages to indicate the saturation and lightness of the hue you pick.

To create Solaris with HSL, for example, use the function hsl(12, 100%, 60%).

You can also specify an alpha channel value with the function hsl(), which accepts an additional value from 0 to 1 and sets the transparency of the color.

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:

See the Pen HTML Background Color - transparency by HubSpot (@hubspot) on CodePen.

Adding Transparency Using the Opacity Property

You can also use the opacity property in CSS.

What's the CSS opacity property?

The CSS opacity property is added to an HTML element (such as a div or a table) or a CSS attribute (such as a class) to make those elements partially or fully transparent. Values for this property range from 0 to 1, with 0 being completely transparent and 1 being completely opaque.

For this tutorial, we'll use two buttons as an example. Let's walk through the process of adding transparency step-by-step.

1. Identify the HTML elements you'd like to make transparent.

If you already know what you want to change, go ahead and find it in your HTML code.

In this tutorial, we have two Bootstrap buttons side by side. We want visitors to click one - the submit button - and not click the other - the "no thanks" option.

Here's the HTML:

We want to decrease the opacity of the latter to make it seem deactivated and drive fewer clicks.

To achieve this result, we'll use the CSS opacity property after adding a class to the button we'll change.

2. Add a class to the element you'd like to change.

Next, we'll assign an additional CSS class to the second button to distinguish it from the first.

We'll add the class btn-secondary to the button we want to deemphasize.

Here's what that looks like:

3. Add the class selector to your CSS code and apply the opacity property.

Now that you've created a new class, it's time to add it to your CSS code.

To make the second button 40% see-through, we'll use the .btn-secondary class selector to apply the opacity property. Then, we'll set the opacity level to 0.4.

Here's the CSS:

Here's the result:

You may have noticed we did not need to use the CSS background-color property because we used Bootstrap's default modifier classes.

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 - Left to Right

No direction was specified for the linear gradient above. That's because top to bottom is the default direction.

If you'd like to specify another direction, then you'll add it in the parentheses, before the color stops.

Here's the CSS for the example above, rewritten so the gradient is left to right.

Here's the HTML:

Linear Gradient - 45° Angle

If I wanted the gradient to go diagonally, then I could use the keywords "to bottom right," "to bottom left," "to top right," or "to top left." If you'd like more control over the direction of your gradient, then you could use angles rather than keywords.

Note that a value of 0 degrees is equivalent to the keyword "to top," 90 degrees is equivalent to "to right," and 180 degrees is equivalent to "to bottom."

If I wanted the gradient to go to the top right, for example, then I could set the direction to 45deg.

Linear Gradient - Multiple Color Stops

To create a linear gradient, you need a minimum of two color stops. But there's no maximum, which means you can use as many as you want. Below is an example with four color stops.
