Join Justin Seeley as he introduces gradients, a somewhat hidden strength of CSS that allows you to add depth and texture to your web designs while reducing load times—creating a better viewing experience for your visitors versus static images. Discover how to create simple linear and radial gradients; apply them to backgrounds, buttons, and text; and write browser-specific syntax to ensure your designs look the same across multiple platforms. The course also shows how to create metallic textures, diagonal gradients, and repeatable patterns. Along the way, Justin demonstrates real-world uses for gradients and techniques to extend them beyond the basics.
All right, so now that we understand how to add more than one gradient stop to our gradients that we create via CSS, it's time to get a little bit more creative with those gradient stops, and start positioning them in different ways. So I have open here a document that has just a big box with a gradient going across it, and it goes red, yellow to red, and it just does that in an even fashion all the way across. So there is an equal amount of red, equal amount of yellow, and another equal amount of red on the right-hand side. So in this gradient, what I want to do is I want to play around with the positioning of this yellow gradient.
And I'm going to do that by telling it where to start in relationship to the overall width of this box. So what I want to do now is go back over into my code, and in order to tell a gradient that it needs to start or stop in a certain location, you have to go to that particular element that you want to control and then give it either a percentage or an actual pixel value. So in this case, what I'm going to do is I'm going to come down here, and I'm going to click right after the word yellow, and I'm just going to make a space, there is no comma after this.
And so once I do that, what I'm going to do is type out 75%. And so basically, once I type out 75%, I have told this gradient that the yellow stop needs to begin 75% of the way along the length of the gradient. So in order to do that, I just created a space, typed out 75%, and there we go! Now, I can do this for the rest of these as well, just typing out 75% right after the word yellow. And remember, it does not require a comma; just 75% all the way across, save it.
Now let's go over here. So in theory, what should happen now, since this goes from left to right--that means the yellow piece, which is right here, should actually move over here to the right. So somewhere right around where my cursor is right now. So if I refresh the page, there we go. And as you can see, I was pretty close to where it needed to be. So basically, the yellow gradient, the actual 100% yellow piece that goes right down the middle there, it does not start until it is 75% of the way over here. This just means that this red on the front-end has a longer fade into the yellow color and this red over here has a shorter fade into the yellow.
Now, if I were to go back over here and change this, let's change everything from 75% to 25%, and let's just replace them all, 25. And just refresh it, there we go! So now it starts 25%, so it's the exact opposite of the last one. So it actually starts 75% of the way away from this side versus that side. So you just have to do that in terms of percentages. Now, you can also do it in terms of pixel values as well. So for instance, I'll look for the percent sign, and I will replace that with a PX value.
And let's replace them all, so now it's all 25 pixels, and we'll save that and go back over. And so, now you see how close, only 25 pixels from the edge is where that starts. So it's not a very long fade at all and a really long fade into that second red. The same holds true if you were to change the direction of the gradient as well. So let's do this left, and we'll change that to bottom, replace all of those. And I'll save that and refresh it. So now, the small little fade should happen down here at the bottom, and then a long fade all the way up to the top. Let's refresh.
There we go! Anytime I want to make a change to that, again, I just come back in here, and let's change the PX value back to a percentage value, and that replaces all of those. And I'll also make sure that I don't replace my Width and Height values, there we go, and save that up, refresh, and there we go. So now it's a little bit more gradual. So as you continue to create gradients and mess around with the positioning of your stops, I think you're going to be amazed at just how creative you can get with these, and all the different types of combinations that you can come up with, and what you are able to simulate whether it be a beveled edge, a texture, or even a repeatable pattern.
