Use CSS shorthand properties wherever possible. This is particularly true for border , margin , padding , and background , but it counts for other properties too. Of the below two examples, which one do you prefer:. If you want to keep your CSS short, think of one of the most important principles of clean code : Don't Repeat Yourself. Consider this:. The CSS in the latter part of the above stylesheet is cleaner and shorter.
Much to the frustration of many web developers, different browsers have slightly different ways of displaying things. Your website that looks one way in Chrome might look another way in Internet Explorer. Fonts might not display, some functionality might not work, line height might be different, etc. That's why you need to use a reset stylesheet.
It reduces the inconsistencies between browsers by overriding the default browser styles. A good stylesheet will explicitly set styles for most HTML elements. There is a wide variety of CSS reset stylesheets to choose.
Alternatively, you can create your own stylesheet with something as simple as this:. Make sure you are consistent with your colors. Choose your brand colors and don't deviate from them. You don't need thirteen shades of red. This means you need to be careful declaring colors with rgba or hsla because those colors will change depending on the background.
Use a hex code instead. Although IDE plugins help visualize which hex code is which color, it's also a good idea to add a color reference so the people reading your code know which colors you'll use throughout the stylesheet.

The class embeds within a document element and requires additional instruction to better define content attributes. Also highly regarded, the duration constraints on animations, along with delays and user animation interaction are available within the Animate.
CSS style sheets list. For the most part, web developers getting started with Annimate. CSS seek animation designs to improve the content on web sites.
Reasonably, the animation should have the ability to perform as a method to attract site visitors to particular information on sites. Therefore, developers should understand how to configure elements in regard to animation delays, speed, and timing.
Presently, Animate. CSS assists developers with delay features with a particular stylesheet. Additionally, element designs on Annimate. CSS have speed time values. The developer may correct the speed of an animation using a specific stylesheet for the class. By default, the element rates set to a standard value of one second. CSS stylesheets. Previously mentioned, developers can manually adjust the Animate. CSS stylesheets to develop new animations separate from the standard defaults.
CSS compatible and offers easy to set up custom animation builds. More specifically, the cross-browser platform is an automation program for task development. For web developers and programmers, The Gulp extension analyzes and organizes a variety of pipe-driven files to support plug-ins on user servers. In this case, Gulp interacts with dependencies for the creation of personalized animation builds and functions.
As a plus, the packaging within Gulp is adjustable to include animate design styles to fit the web content. With Javascript, the Animate. CSS library module enables users with additional features for designing web applications. The features include more specific animation functions with specific directional instructions, animation timing signals, adding and removal animation keys, and post animation effects.
Also, Javascript offers better cross-browser functionality for the Animate. CSS extension and allows users more flexibility on which decelerations perform best for user software.
In summary, Animate. The design encourages developer creativity with compatibility for alternative dependencies and includes numerous animate design features. Along with different versions of design stylesheets, animation behavior also changes through programmer text interaction.
Web application developers, with the support of Annimate. CSS, create more responsive websites with quality animations that are easy to maintain and provide unique website interaction.
Writing good code is about more than just getting the results you want on a webpage. Good code should be as efficient and concise as possible. While there are often numerous ways to achieve the same results, the most succinct and simple method is, with few exceptions, the ideal choice. There are two major benefits of writing good, clean code. Firstly, it can dramatically improve site speed and performance.
The smaller your file is and the fewer external requests you are sending the less time it will take for your website to load in the browser. Secondly, writing good code has the invaluable benefit of making it easier to maintain.
Best practices for writing good code are often applicable to all programming languages, although this post will specifically be tailored to improving the CSS on your website. Many times in the process of developing a website, you may end up with multiple external files and dependencies linked to from your HTML document or CSS files. Each one of these dependencies represents an HTTP request your site is making each time it is loaded in the browser.
This puts a great strain on site load time, and all of these requests add up pretty quickly. Are you only using a CSS framework for just a few lines of code? Consider copying and pasting these lines to your main. While writing CSS, you may end up repeatedly writing the same rules for various different elements and selectors. Anytime you find yourself writing the same CSS rules for different selectors, find a way to consolidate them.
While this may not seem like a big difference at least in terms of lines of code , the total count of characters has been significantly reduced, which will have an impact on page load times. Additionally, it consolidates elements and selectors that are utilizing the same styles, making it clearer to see what common styles are being applied to different elements.
For example, for an error message, it can often seem to make sense to use red as the class or ID value, like so:. But what happens if you change the color or other styles of this class? This class will no longer have a direct relation to its content or presentation, and will most likely cause confusion. A better choice in this situation would be to use a class value that explains its function, rather than its stylistic presentation:. Style can change many times throughout the process of creating a site, but using descriptors for functions will make the code much more readable and easy to maintain.
There are often many different ways of selecting an element, but there are often more efficient ways than others. While it is possible to nest selectors inside of each other in order to get to a specific element, if you find yourself having to go too many levels in, it might be best to reassess if a class or ID value would function better. In the process of styling your webpage, you may try out a variety of different colors, for example many shades of the same color.
A good tool to use to check for these types of redundancies is cssstats. Not only will this simplify your code, it will also make your overal design much more consistent, rather than having 40 different shades of a color on the site.
A minifier will remove all white space from your source code, significantly reducing the file size. Since source code does not rely on white space for its functionality only its readability , this will have no negative affect on how your site runs.
One option is cssminifier. As was briefly touched on in the last post, it is a good idea to consolidate your resources as much as possible. While there is a good argument for keeping CSS modular during the development stage such as keeping layout rules in one CSS file, color options in another, etc. Although popular libraries like Animate. By taking advantage of the animation properties built in to CSS, you can create much more complex and customized animations far beyond just motion.
CSS animations can effect element color, size, position or any other property available in the CSS3 specification. This post will give an introduction to getting started with the native CSS3 properties and some examples of possible uses for them. To give an HTML element animation, the first two steps are to declare a name for the animation and a duration. This is done with the animation-name and animation-duration properties:. This is done using the keyframes rule, followed by the animation name:.
This can be thought of much like a video or flipbook, where each page of the book is a unique frame that when combined, creates motion:. The power of using custom animations, though, is that you can change absolutely any CSS properties, with any level of incremental change in frames.
A good example of this is for :hover pseudo-classes. CSS :hover states are often used to apply a color or minor stylistic change when an element is hovered over with a mouse, but animations allow these changes to be much more detailed. Its background-color changes in four equal steps over a duration of 5 seconds, with the size of the element itself changing in discreet, unique steps as well original, to 2.
One additional property included in the example above is the animation-fill-mode property. This property can be used to indicate how styles should be applied before and after the duration of the animation has completed. Without the addition of the animation-fill-mode property, the styles of button would revert back to their original state after the animation had completed.
CSS animations can be very complex and detailed, with up to distinct frames able to be specified. Considering this feature is available natively in vanilla CSS, they are a great way to add visual interest and complexity to a web project, well-supported in all modern browsers.
Since the introduction of CSS3, it has been possible to use color gradients as a background, with 2 or more colors gradually fading into each other. Previously, creating gradients had to be done using Photoshop or other image editing software. Used effectively, this is a great way to add interest and even texture to webpage designs, beyond just static background colors.
While legacy versions of Internet Explorer do not support this feature, you can safely add them to a project, as all modern browsers do support it. This post will take a look at using gradient backgrounds, and the available customization options. To set the background of an element whether it be the body , a div , or other element , the background property is used, typically with a color value:. To use a linear gradient instead of a solid color, include at least two colors using either hex, rgb, hsl, or named colors values , separated by commas, inside of the linear-gradient value:.
Since different browsers handle the linear-gradient value differently, it is highly recommended to use vendor prefixes along with it. This will ensure that the value is understood by Safari, Firefox, Chrome, and Opera.
To use vendor prefixes, simply add 2 additional background rules with the linear-gradient value prefixed with -webkit- and -moz-.
They should also appear before the regular rule without any vendor prefix:. By default, gradients will transition from top to bottom, with the first color included in the linear-gradient value being the top color.
You can change the direction of the gradient, though, by adding some direction keywords before the colors i. When setting the direction to a corner, either the x- or y- axis can be stated first i.
You can utilize more than two colors in a gradient, simply by comma separating them:. Sometimes you will want to control where a certain color begins, allowing for certain colors to take up more space or have a wider space to transition. This is great for having finer control over your transitions, and can be used for interesting effects. One available variation on linear gradients are radial gradients. Radial gradients will transition from the center of the element, transitioning outward like a circle.
They use almost the exact same syntax as linear gradients, just with the radial-gradient value instead:. One of the most important properties in CSS to understand is the position property. While much can be done to layout elements on a page without explicitly changing values for the position property, most advanced layout issues will require knowing the different values available for this property.
This blog post will take a look at the four main values for position , and the instances in which you might use each of them. Elements with a position of static will not accept any box offset properties, such as margin or padding.
In the example below, each div will be stacked on top of each other, since each is a block-level element:. Elements with a position of relative are very similar to the value of static , although with one major difference: they can accept box offset properties of top , right , bottom , and left.
