How To Declare Values For Multiple Properties In a CSS Rule

In this tutorial, you will learn how to declare values for multiple properties in a CSS rule. Declaring multiple properties in a single rule allows you to apply many style instructions—such as size, color, and alignment—to an element all at once. We’ll also explore creating a variety of CSS rules that allow us to apply different styles to different pieces of content in a single HTML document.

Prerequisites

To follow this tutorial, make sure you have set up the necessary files and folders as instructed in a previous tutorial in this series How To Set Up You CSS and HTML Practice Project.

Creating a CSS Rule With Multiple Declarations

To add more than one declaration to a CSS rule, try modifying your rule in your styles.css file (or adding the entire code snippet if you haven’t been following the tutorial series) so that it includes the additional highlighted declarations:

h1  color: blue; font-size: 100px; font-family: Courier; text-align: center; > 

Save the file and reload your HTML document in your browser. (For instructions on loading an HTML file, please visit our tutorial step How To View An Offline HTML File In Your Browser). Your text should now be located in the center of the page, have a size of 100 pixels, and render with the Courier font:

In the next section, we’ll add more CSS rules to extend the styling possibilities for the webpage’s content.

Creating Multiple CSS Rules To Style HTML Content

In this section we’ll add some more text to the index.html file using an HTML

element. We’ll experiment with modifying its properties using a new CSS ruleset that only applies to

tags.

In the index.html file, add a line containing

Some paragraph text

below the existing A sample title line that you added in the How To Understand and Create CSS Rules tutorial:

h1>A sample titleh1> p>Some paragraph textp> 

Save the index.html file and reload it in the browser window to check how the file is displayed. Your browser should render a blue heading that says “A sample title» and an unstyled paragraph below it that says “Some paragraph text» like the following example:

Next, let’s add a CSS rule to style the

element. Return to your styles.css file and add the following ruleset at the bottom of the file:

. . . p  color: green; font-size: 20px; font-family: Arial, Helvetica, sans-serif; text-align: center; > 

Save the file and reload it in the browser window to check how the file is displayed. Your

text should now have the style you declared in the CSS rule you just created:

Now that you have CSS rules for the and

elements, any text you mark up with these tags in your HTML document will take on the style rules that you declared for these elements in your styles.css file.

Further Practice

If you want to continue experimenting with CSS rules, try creating CSS rulesets for different HTML text elements—such as , , and —and using them to modify text in your index.html file. If you’re stuck, you can copy the CSS rules in the following example and add them to your styles.css file:

. . . h2  color: red; font-size: 40px; > h3  color: purple; font-size: 50px; > h4  color: green; font-size: 60px; > 

Save your file and then add the following HTML content to your index.html file:

h2> This is red text with a size of 40 pixels. h2> h3> This is purple text with a size of 50 pixels. h3> h4> This is green text with a size 60 pixels. h4> 

Save the file and load index.html in your browser. You should receive the following results:

Conclusion

In this tutorial you experimented with specifying values for multiple properties using CSS. You also created multiple CSS rules for styling text content in an HTML document. You will expand upon both these skills when you begin building the demonstration website later on in the tutorial series. In the next tutorial, you will begin exploring how to style images with CSS.

How to add multiple CSS inline html

You gain the most flexibility and power by putting your CSS in a separate CSS file. If you to that CSS file on more than one HTML page, you can reuse the same stylesheet for multiple pages. If you want a consistent style across your whole website, this is the way to go. When you want to make a change, you will only need to make the change in one file, and it will be seen in each linked page.,Sometimes, inline styles are necessary. If you are building a web page by hand, however, you should avoid them whenever possible. Using a separate CSS file is the most powerful and flexible method.,Inline styles are not so different from the other ways you can write CSS. For example, the inline style above is almost like the following CSS rule:,A short guide on when and when not to use inline CSS styles in HTML.

Inline styles look and operate much like CSS, with a few differences. Inline styles directly affect the tag they are written in, without the use of selectors. Here’s a basic HTML page using inline styles:

      
I'm a big, blue, strong paragraph
  

      
I'm a big, blue, strong paragraph
  

The p tag with the inline style attribute is the focus here:

To use inline styles, add the style attribute to the relevant element. The style attribute can contain any CSS property.,Inline styles are defined within the «style» attribute of the relevant element:,What style will be used when there is more than one style specified for an HTML element?,The internal style is defined inside the element, inside the head section.

Note: Do not add a space between the property value and the unit (such as margin-left: 20 px; ). The correct way is: margin-left: 20px;

The above example code should work perfectly. The only drawback, however, is that it overwrites all other inline styles applied to the element.,The simple way is to just create a new element, add your CSS properties using innerHTML, and append it to the DOM:,The above code is more readable and maintainable. Also Object.assign() doesn’t overwrite all existing inline styles. Instead, it will only update those properties that match the keys in the styles object., The newsletter is sent every week and includes early access to clear, concise, and easy-to-follow tutorials, and other stuff I think you’d enjoy! No spam ever, unsubscribe at any time.

Usually, when you want to add multiple CSS properties to an element, you have to set them individually as shown below:

const btn = document.querySelector('.btn'); // set inline CSS styles btn.style.width = '150px'; btn.style.height = '40px'; btn.style.color = 'blue'; 

One way to solve this issue is by using the cssText attribute provided by the style property as shown below:

btn.style.cssText = 'width: 150px; height: 40px; color: blue'; 

Another way to apply multiple CSS styles right away is by using the Object.assign() function:

const btn = document.querySelector('.btn'); // create styles object const styles = < width: '150px', height: '40px', color: 'white', backgroundColor: 'black' >; // apply styles to the button Object.assign(btn.style, styles); 

The simple way is to just create a new element, add your CSS properties using innerHTML , and append it to the DOM:

// create style element const style = document.createElement('style'); // add CSS styles style.innerHTML = ` .btn < color: white; background-color: black; width: 150px; height: 40px; >`; // append the style to the DOM in section document.head.appendChild(style); 

Alternatively, you can also declare all CSS styles as a class in a CSS file, like below:

And then, simply add the class to the element using JavaScript:

const btn = document.querySelector('.btn'); // add CSS class btn.classList.add('btn');

You can add multiple styling properties at once when using the HTML style attribute — just make sure to separate the name-value pairs with commas.,Using inline CSS for HTML styles is the best option when you need to change the look of a single element.

Grouping Multiple CSS Selectors

When you group CSS selectors, you apply the same styles to several different elements without repeating the styles in your stylesheet. Instead of having two, three, or more CSS rules that do the same thing (set the color of something to red, for example), you use a single CSS rule that accomplishes the same thing. The secret to this efficiency-boosting tactic is the comma.

How to Group CSS Selectors

To group CSS selectors in a style sheet, use commas to separate multiple grouped selectors in the style. In this example, the style affects the p and div elements:

In this context, a comma means «and,» so this selector applies to all paragraph elements and all division elements. If the comma were missing, the selector would instead apply to all paragraph elements that are a child of a division. That is a different kind of selector, so the comma is important.

You can group any form of selector with any other selector. This example groups a class selector with an ID selector:

This style applies to any paragraph with the class attribute of red and any element (because the kind is not specified) with an ID attribute of sub.

You can group any number of selectors, including selectors that are single words and compound selectors. This example includes four different selectors:

This CSS rule would apply to:

• Any paragraph element
• Any element with the class of red
• Any element with an ID of sub
• The link pseudo class of the anchor elements that are descendants of a division.

That last selector is a compound selector. As shown, it’s easily combined with the other selectors in this CSS rule. The rule sets the color of #f00 (red) on these four selectors, which is preferable to writing four separate selectors to achieve the same result.

Any Selector Can Be Grouped

You can place any valid selector in a group, and all elements in the document that match all the grouped elements will have the same style based on that style property.

Some designers prefer to list the grouped elements on separate lines for legibility in the code. The appearance on the website and the load speed remains the same. For example, you can combine styles separated by commas into one style property in one line of code:

or you can list the styles on individual lines for clarity:

Why Group CSS Selectors?

Grouping CSS selectors helps minimize the size of your stylesheet so it loads faster Admittedly, style sheets are not the main culprits in slow loading; CSS files are text files, so even very long CSS sheets are tiny when compared to unoptimized images. Still, every bit of optimization helps, and if you can shave some size off your CSS and load the pages that much faster, that’s a good thing.

Grouping selectors also makes site maintenance far easier. If you need to make a change, you can simply edit a single CSS rule instead of multiple ones. This approach saves time and hassle.

The bottom line: Grouping CSS selectors boosts efficiency, productivity, organization, and in some cases, even load speed.
