Introduction to CSS 

CSS represents Cascading Style Sheet. Where HTML is the thing that characterizes the structure and substance of a website page, a Cascading Style Sheet is a web record that permits you to change the presence of the HTML.

CSS permits you to change the size, style, textual style, and shade of content; edges and cushioning; foundation hues and fringe styles. It can likewise be utilized to situate components on a page.

CONSISTENCY IS KEY

The best thing about CSS is that permits you to make worldwide style changes that influence each case of a specific element all through your blog or site with the goal that you don't need to roll out these improvements at the individual page level. This spares you a huge amount of opportunity with regards to overhauling your blog.

Here's a case of what I mean: as we learned, the page title on a blog page is characterized by an HTML component called an H1 (heading 1). As a matter of course, the program shows an H1 as additional huge, strong, dark content, much like we found in the PAWS model.

In the event that we need to change the shading, textual style and size of all the H1 are on our blog to keep consistency all through, you should simply characterize what all H1's will resemble in your CSS.

Here and there various programs may show marginally extraordinary default styles. Utilizing a template to characterize what a particular component ought to resemble can keep the appearance of your blog steady starting with one program then onto the next just as one gadget to another.

HOW DOES CSS WORKS?

THE CASCADE

A significant bit of CSS is the "Cascading" part. The program peruses style definitions through and through in a template. This implies a style you characterize lower in the template will abrogate any past styles characterized before in the template.

You can likewise have a template abrogate another template. This is the manner by which we can abrogate predefined styles from our blog topics or module gadgets, as our custom template is typically the last one read by the program.

Characterizing MULTIPLE ELEMENTS

There's no compelling reason to reclassify the textual style family and the shading since they've just been characterized up above. This additionally makes it simpler later on the off chance that you choose to change your text style to something different. You just need to transform it once rather than multiple times!

Whichever way is right in light of the fact that the program will comprehend the two techniques, however
an) it's speedier for you to compose and alter adaptation 2 and
b) it encourages your CSS to stack quicker in light of the fact that you're keeping the record size littler by removing the reiteration.

Different ELEMENTS 

We can style something other than content in our CSS. We can characterize the vibe of a gadget or picture for instance. Suppose you need a dark outskirt around the entirety of your pictures. Recollect our <img> tag?

img {
border-width: 1px;
border-style: solid;
border-color: #000000;
}

CSS CLASSES

Presently suppose you didn't need certain pictures on your website page to have a fringe on them, similar to your symbols for instance. We can add a class to those components in the HTML to explicitly target them. You can name a class anything you desire, you simply need to name it something that bodes well. Likewise, note that there are never any spaces in class names. In CSS, all class names start with a dot.

TROUBLESHOOTING AND COMMON SYNTAX ERRORS

At times in the wake of altering your template, you may get a blunder or locate that a specific style definition isn't working when you invigorate your program window. In many cases, these are brought about by punctuation mistakes. Programs can be extremely specific with regards to appropriate grammar and one little slip-up can perplex everything. In the event that this occurs.

• Check your template for missing semi-colons, spelling blunders or missing opening and shutting wavy supports.
• Did you overlook the dot before a class name or include a speck before a HTML component?
• Are there commas between different selectors?

Your mistake might be in your HTML: 

• Did you follow the word 'class' with an equivalent sign and no spaces?
• Did you encompass the class name with twofold statements?
Is the class name spelled precisely the equivalent in the HTML all things considered in the CSS?
