If we go up to an ID that is even more specific because unlikely a class there can be only ONE item with a particular ID. If we go up to our specific class settings that is one step MORE specific because we are explicitly saying this element should have this style. For example in our inheritance example above the paragraph was IMPLIED to be bold because it is in a div with bold styling, that is the LEAST kind of specific. Basically, the MOST specific selector wins for styling.
This is probably the hardest part of CSS to understand and that is specificity. This still gets bold styling because it is inherited from the outer element CSS is styled in order of specificity Finally, there is the external style sheet which loads in style sheets from other locations on the net. Next we can put css into a special style element (remember elements use tags). Using a CSS selectors allows us to apply the same style attribute to all members of a class or instance of an ID without needing to copy the style=”” stuff to each element one by one.ĬSS can be added to your html in many ways, you remember our style attribute (remember attributes are in the form attribute=””) in the previous section that is what is called inline css. How does CSS Work?ĬSS works on a system of “selectors” like the name of the html element or an attribute like class or ID. Surely there must be a better way right? There is, that is where CSS comes from. Now imagine we change our mind and don’t want that text bold anymore, this would mean changing EVERY paragraph elements style attribute one by one. Imagine doing that for every paragraph across a website. Take a look at our last HTML example for inline css styling above, notice that for every element we’d want to be bold we’d need to add style=”font-weight: bold ” to.

In modern web development HTML and CSS really cannot live without each other. Attributes are written inside the first set of and are in the form XYZ=”” Which is better HTML or CSS? The style attribute can be used to style elements, in this example by making the font bold. Links also have attributes like where is the link pointing to or does it open in a new tab. Images are perhaps the easiest to understand, for example the width and height of an image are “attributes”. Each element also has properties unique to them called, “attributes”.
