CSS Grouping and Nesting Selectors

When using style sheets, you might encounter having to make elements that are very similar. This might seem like a very cumbersome way of making a page. The good news is that for anything that is highly repetitive, there is a good way of simplifying things.

CSS Grouping and Nesting Selectors

Instead of having to create similar elements, you can use nesting and grouping selectors in order to make things a lot simpler for you. Here is an example of a page with very similar elements to it:

h1

{

color:red;

}

h2

{

color:red;

}

p

{

color:red;

}

You can minimize this code by the use of groupings and selectors. When you use several selectors, you just have to separate each with a comma so that each would be indicated as separate. With the use of nesting, you can set the styles to be used on the whole selector. This method of creating the code could save space and more importantly, time. But you should remember that the use of nesting and selectors is only going to be possible if the sheet that you are creating has a good structure to it.

Benefits of Using Selectors

A developer would be able to benefit from the use of selectors by being able to handle codes of very large size. It can save a great deal of time since there would be a lot less code to be created. We have also mentioned earlier that it can save on the amount of space to be taken up in coding. Here is a good example of how the above code that we have shown, with very similar elements can be coded differently using grouping selectors:

h1,h2,p
{
color:red;
}

As compared with the original code, this one is much simpler and eats up less space. The end result would be the same.

Using Nesting Selectors

You can also define a selector within an existing selector that you have created. Here is an example code that uses nesting selectors:

p

{

color:green;

text-align:center;

}

.marked

{

background-color:blue;

}

.marked p

{

color:red;

}

 

In this code you would see that a style has been set for all of the p elements within it. Using selectors another style has been defined for the elements that would fall under the “marked” classification. Then there is a third style that is selected for all the p elements that would fall under the marked classification. Using this method you can set selectors within existing selectors that you have created.

The benefits of the use of grouping and nesting selectors could not be overemphasized. A developer would obviously benefit from such a simplified way of coding. By using this method as well, you can save on the space that would be taken up by the code.

If you are unfamiliar with selectors, then you better start with some simple examples first and then you can move on to even more complex codes that you can use.
