with an ID of “container”, which is a descendant of the .

.nav a {
    color: blue;
}

If your CSS isn’t organized, it can be no longer simple to hunt out and change varieties. This can result in difficulties in maintaining your code, specifically when working with large stylesheets or in a staff atmosphere.

Example:

Let’s say you’ve were given a CSS report with plenty of lines of code, and the categories are all combined up:

h1 {
    color: blue;
}

.footer {
    background: black;
}

h2 {
    color: green;
}

.header {
    background: white;
}

In this example, the categories for more than a few sections of the internet web page are scattered all through the CSS report. This may increasingly make it no longer simple to hunt out the categories for a specific phase when you want to switch them.

Restore:

/* Header */
.header {
    background: white;
}

h1 {
    color: blue;
}

h2 {
    color: green;
}

/* Footer */
.footer {
    background: black;
}

In this example, the categories are grouped throughout the phase of the internet web page they apply to. This makes it easier to hunt out and substitute the categories for a specific phase.

.header {
    background-color: #007BFF;
}

.button {
    background-color: #007BFF;
}

.link {
    color: #007BFF;
}

In this example, the identical color value is repeated thrice. If making a decision to modify this color, you would have to to seek out and substitute each and every instance of it in your CSS.

:root {
    --main-color: #007BFF;
}

.header {
    background-color: var(--main-color);
}

.button {
    background-color: var(--main-color);
}

.link {
    color: var(--main-color);
}

In this example, the color value is stored in a variable known as --main-color, and this variable is used any place the color is sought after.

There are also equipment available that mean you can with cross-browser testing, very similar to BrowserStack and BitBar.

In case you in finding {{that a}} certain CSS feature isn’t supported or behaves otherwise in a certain browser, you’ll use feature queries (@is helping rule) to provide a fallback:

.container {
    display: flex;
}

@is helping (display: grid) {
    .container {
        display: grid;
        grid-template-columns: repeat(3, 1fr);
    }
}

In this example, the container will use the flex construction thru default. If the browser is helping CSS Grid (as determined throughout the @is helping rule), it’ll use the grid construction as an alternative.

The serve as of cross-browser testing isn’t to make your internet web page look exactly the identical on all browsers, alternatively to make sure a relentless and usable enjoy for all shoppers.

    margin: 0 auto;
}

In this example, the container will soak up 100% of the computer screen width on smaller displays, and it’ll be centered with a maximum width of 1200px on higher displays.

You’ll moreover use media queries to make use of totally different varieties for more than a few computer screen sizes. For example:

    .container {
        width: 1170px;
        margin: 0 auto;
    }
}

In this example, the container will probably be whole width on displays smaller than 768px, 750px huge on displays between 768px and 1199px, and 1170px huge on displays which may also be 1200px or higher.
