CSS Tutorial — Selectors, Element, Class and ID (3/13)
So we just looked at a basic CSS statement and it starts with a selector. So what the hell are selectors, again?
Say you are brangelina, and you have a bunch of kids, you wanna dress them for school except only one of them is old enough for school. So first you have to pick the right kid, then dress/style them. That’s what selectors are. Choose which kid you wanna prepare for school. Or since you’re not brangelina, Choose which element you wanna style. It all starts with the selector.
There are different kinds of selectors. In our example, we used what’s called an element selector because it targets your styles based on the element type, That’s the most basic selector there is. By using the element type. Like a p tag. Cool? Cool.
The problem with element selectors is that you might not want to turn ALL your paragraphs blue. What if you had 3 paragraphs and you only want one of them to be blue? The element type is an identifier but in this case it’s too general.
I wanna show you an example. Look at this thing on atom’s website. See these two sections? One of them has a white background, the other one is beige. If you inspect it you’ll see they’re both divs, here they are, so clearly the dudes who made this couldn’t have said oh select all divs and change the background to white or beige. They needed to be more specific.
You can select elements based on other kinds of identifiers. Classes and ID. Class is the most common and useful one, in fact that’s exactly what Atom is using. Take a look. They have wrapper class on one, and highlight on the other. If you click on highlight, you’ll see that class has a beige background on it.
So let’s do one ourselves. Let’s say you have 4 paragraphs and you want to alternate between dark and light. So dark, light, dark, light. In other words you wanna reuse a style for multiple elements. In this case you can use a CLASS selector. The way you write these in CSS is you write the name of your class, this could be whatever you want, just can’t have spaces and some special characters, say DARK, and you put a DOT in front of it. Why a DOT? Well, I dunno what to tell you. There’s no good explanation why, that at least I know about. It’s just syntax that you have to remember. This tells the browser hey this is a CLASS selector. Then of course you have to add the class to your element in HTML.
This means “hey select all the elements that have a class attribute and the value is dark. Let’s try it:
DEMO 4 -
I’m gonna cover ID selectors too just for the sake of it although we don’t use them much. ID attributes are specific to one element only. If you have a style that you want to apply to only one element, for some reason, you can add an ID to that element (for example: my-blue-paragraph), then use an ID selector in CSS to style it. ID selectors are just like CLASS selectors, except you put a # in front of the name instead of the DOT. That becomes the CSS selector for the element with that ID. So let’s try it.
DEMO 3 -
The problem with ID is that it’s limited to only 1 element. Remember IDs can’t be shared between elements. So you can’t reuse my-blue-paragraph ID for multiple elements.
So those are the 3 basic selectors. Element, Class and ID. “Element” to style the elements of that type. ID to target only one specific element. And Class to reuse for multiple elements. We’ll be using all of them from now on. Selectors can get much much more complicated and they will, but now you know the basics.
So next, we’re gonna look at some of our options when it comes to style properties, like color, so far that’s all we’ve used so I’m gonna talk about it in detail. Later, fonts, sizes, background, border, animations, display types, flexbox, where’d everyone go? I was talking.
Dude! Great presentation. Great graphics (not overbearing). Great subtle and humor and metaphors. Great pacing (not speaking to me like I'm a 4 yr old all slow and simple. Thank you for not taking me through a trip to file linking land, a review of such, or 5 minutes of self-promotion}. Now I just need to look at your channel to see if you got anything that uses combonations of selectors and psudos.
Thanks Joseph for that awesome comment. I've added pseudo selectors to the list of videos for the next CSS Course. Make sure you subscribe so you'll get a notification when I release it. In the meantime the CSS Basics course should give you plenty to play with. Happy coding :)
Learning how to draw cartoon animals from the farm is not such a difficult task! Weve grown up surrounded by them! Farm animals are everywhere: In blockbuster movies, childs books, greeting cards. their shapes and images are printed in our minds!
In this section, I will show you how to determine what are the physical uniqueness of each animal and how to work with them. Then, you can practice drawing each cartoon character using basic shapes.
You will have the opportunity to make nice illustrations, practice sketching and cartooning using short easy lessons and complete your creation using a drawing software to create vector art if you want to! Cartoon drawing is really fun once you get into it!
Dont be afraid to try until you get it right. This method is really simple, but requires practice and observation. So, sit back and relax. Learn how to draw animals from the farm and start your journey on a good note!
Lets try s few basic characters to get started! :)
A cute turkey to begin with.
In this first tutorial, you can learn how to draw a fun turkey mostly made from small rectangles and large circular shapes. The posture of the character is really interesting. Not only is it easier to draw than a front version, but its also easier to add some perspective (as we can see with the legs). The fact that we just need to draw one wing is also interesting.
Most of these cartoon animals are not filled with complex textures or digital effects. In this case, the subject is filled with plain colors and only a few basic details (inside the tail) were added.
A nice turtle also from a side view.
