7 CSS Best Practices Every Developer Should Know
7 CSS Best Practices Every Developer Should Know
CSS stands for Cascading Style Sheets. It’s used to create visually appealing websites. Using it makes the process of creating effective web pages much easier.
A website’s design is crucial. It enhances the site’s aesthetics and overall quality by facilitating user interaction. While it’s possible to create a website without CSS, visual design is essential because no user wants to interact with a boring, unattractive website. In this article, we discussed seven CSS best practices that every developer will need at some point in their web design process.
Creating Responsive Images with CSS
Using a variety of techniques known as responsive https://coder-cafe.com/wp-content/uploads/2025/09/images, it’s possible to load https://coder-cafe.com/wp-content/uploads/2025/09/images correctly regardless of the device’s resolution, orientation, screen size, network connection, or page layout. Images shouldn’t be stretched by the browser to fit the page layout, and downloading them shouldn’t take too long or use too much network traffic. Because https://coder-cafe.com/wp-content/uploads/2025/09/images load quickly and appear crisp to the human eye, they improve the user experience. To create a responsive image, be sure to use the following syntax:
img{
max-width: 100%;
height: auto;
}
The simplest technique for creating high-resolution photos is to set their width and height to half their actual size.
Centering an Element’s Content
If you want to center the content of any element, there are various methods. The simplest method is mentioned below.
Position Properties
Use CSS position properties to center content. Use the following syntax to specify them.
element{
position: absolute;
left: value;
top: value;
}
Example
<!DOCTYPE html>
<html>
<head>
<style>
h1{
text-align: center;
}
div{
position: absolute;
left: 45%;
}
</style>
</head>
<body>
<h1> Position property </h1>
<div> This is an example. </div>
</body>
</html>
Using the <center> Tags
The content you want to align in the center should be written inside the <center> tags. Then, the entire content will be centered.
Using the text-align Property
If the content you want to center consists solely of text, you can simply use the textalign property.
text-align: center;
Using the Universal Selector
The CSS asterisk (*) selector, also known as the CSS universal selector, is used to select or match all elements or portions of elements on a web page at once. Once selected, you can use any CSS custom property to style them accordingly. It can match any type of HTML element, such as <div>, <section>, <nav>, <button>, and can also be used to select and style child elements of a parent element.
Universal selectors are used to set styles for literally every element on a web page. Maintaining a specific style for an entire page is difficult due to browser defaults. This allows developers to create a default style for a web page. The most common use is to style all elements on a web page.

Example
<!DOCTYPE html>
<html>
<head>
<style>
*{
color: green;
text-align: center;
font-family: Imprint MT shadow;
} </style>
</head>
<body>
<h1>Css Universal Selector</h1>
<h2>This is an example. It shows how to style the whole document altogether.</h2>
<div>
<p class = "para1"> This is the first paragraph. </p>
<p class = "para2"> This is the second paragraph </p>
</div>
</body>
</html>
Overriding CSS Styles
Usually, to override CSS styles, we use CSS classes. However, if you want to specify that a particular style must be applied to an element, use the !important
syntax.
element{
property: value !important;
}
Example
<!DOCTYPE html>
<html>
<head>
<style>
h2 {
color: blue;
}
.demo {
color: red !important;
}
</style>
</head>
<body>
<h2> This is an example #1 </h2>
<h2> This is an example #2 </h2>
<h2> This is an example #3 </h2>
<h2 class= "demo"> This is an example #4 </h2>
<h2> This is an example #5 </h2>
</body>
</html>
Scrolling Behavior
element{
property: value !important;
}
<!DOCTYPE html>
<html>
<head>
<style>
h2 {
color: blue;
}
.demo {
color: red !important;
}
</style>
</head>
<body>
<h2> This is an example #1 </h2>
<h2> This is an example #2 </h2>
<h2> This is an example #3 </h2>
<h2 class= "demo"> This is an example #4 </h2>
<h2> This is an example #5 </h2>
</body>
</html>
A sophisticated and efficient user experience is the most critical factor in web design. If your website isn’t user-friendly, there’s no point in having it. To ensure a smooth user experience, you should add smooth scrolling to your website.
The scroll-behaviour property allows developers to specify how a page behaves during scrolling.
html{
scroll-behaviour: smooth;
}
Add media queries and make typography responsive
Media queries with a media type are used to style content when that media type matches the device type on which the document is displayed.
@media (max-width: 100px){
{CSS rules….
}
}
If your site is intended for viewing on different devices, it’s best to use viewport units. This ensures that content resizes to the viewport.
- vw – Viewport width
-
vh – Viewport height
-
vmin – Minimum viewport height
-
vmax – Maximum viewport height
CSS Flexbox
A CSS Flexbox is a container that holds several flexible elements. Flexible elements can be arranged into rows or columns as needed. Flex items are children of a flex container, which is its parent. Using CSS flexbox, each element is given a refined and attractive appearance.
display:flex helps developers make each component appear appropriate and pleasing. It arranges the child elements of an element into rows or columns, aligning them.
It arranges the child elements of a parent element into rows or columns.
Example
<!DOCTYPE html>
<html>
<head>
<style>
.flex-container {
display: flex;
flex-direction: row;
flex-wrap: nowrap;
background-color: #097969;
align-items: center;

.demo1{
order: 1;
}
.demo2{
order: 4;
}
.demo3{
order: 2;
}
.demo4{
order: 3;
}
</style>
</head>
<body>
<h1>Order of Flex Items</h1>
<p>The following list of flex elements has them in an ordered arrangement thanks to the order property:</p>
