Video: Working with color: Solution

Welcome back! I hope you had fun working on our Color Lab. Let's compare your solutions to mine and discuss the thought processes behind the syntax that I used. So I have the main.css here open from the 06_09 finished_files>_css directory, I know that seems complicated, but it's really not. I am sure you will find it with little to no problem at all. Okay, the first thing I want to focus on is the color palette here. If I scroll down, I can see that I have got the three hexadecimal values that correspond to the rgb values.

8h 49m Beginner Nov 22, 2011

Viewers: in countries Watching now:

In this hands-on course, James Williamson demonstrates the concepts that form the foundation of Cascading Style Sheets (CSS), including styling text, adding margins and padding, and controlling how images display. The course also explores the tools needed to work with CSS, the differences between embedded and external styles, how to use selectors to target elements, and what to do when styles conflict.

Topics include:
  • Exploring default styling
  • Writing a selector
  • Setting properties
  • Working with common units of measurement, including ems and pixels
  • Structuring HTML correctly
  • Understanding the cascade and inheritance
  • Setting a font family, font size, text color, and more
  • Understanding the box model
  • Styling container elements
  • Working with RGB vs. HSL values
  • Styling drop shadows

Working with color: Solution

Welcome back! I hope you had fun working on our Color Lab. Let's compare your solutions to mine and discuss the thought processes behind the syntax that I used. So I have the main.css here open from the 06_09 finished_files>_css directory, I know that seems complicated, but it's really not. I am sure you will find it with little to no problem at all. Okay, the first thing I want to focus on is the color palette here. If I scroll down, I can see that I have got the three hexadecimal values that correspond to the rgb values.

So check your values and make sure yours match mine. You are also going to notice that we were unable to take advantage of the hexadecimal shorthand notation, because we don't have matching pairs all the way through. Now if I scroll down for the second objective we were first to define a default color for the html tag, and if I scroll down to around line 116 or so, in my global styles, I can find here is my html selector, and we went ahead and just did a regular background rgb definition. Now I used RGB throughout most of the site.

Now I do throw in occasionally a hexadecimal notational value, and I don't think I used any hsl. There's nothing wrong with mixing color value notations. The browser really doesn't care. The only thing is that you might want to develop a strategy for yourself about which color value notation you are going to use and you might want to stick with that. I recommend using the one that's easiest for you. Hexadecimal has been supported forever in a day, so you can use it without fear of a browser, maybe not, rendering that properly. RGB and HSL are little bit more recent, but they are enjoying fairly widespread support.

RGB maybe a little bit more than HSL. So decide which one you are comfortable with, test it thoroughly and then just stick with it. Now if I go down to our third challenge, which was the banner paragraph. I am going to scroll down a line around 288, that's where this is found. All right, so here is our (.banner p {), and for the background, notice I wanted it to be semi-transparent, so I used the rgba property. I passed in the values for that Pewter Blue color from the color palette up top, and then I passed in that 80% Opacity using the .8 notation, and notice that here I use the rgba notation for the background rather than Opacity and I did that because we only wanted the background to be transparent, we did not want the content to be transparent.

Now I used a similar solution for the gallery h1 rules. So I am going to scroll down to around 419 and there I can find that gallery h1 rule, and you can see a couple of things that I added to it here. I just did a normal rgba declaration this time of the color property and not the background, again, because it's the actual text itself that I wanted to be semi-transparent. So I passed in a 60% transparency here, and then here is my text-shadow. Notice that I only wanted to offset it by two pixels. I didn't want any blur at all, so I used 0, and then I passed in the rgba notation of that Pewter Blue color again with a 60% transparency, so that the color and the text-shadow could sort of mix together and form that sort of embossed look that we were going for there.

Now again pay attention to the syntax here, how we use white space and not commas to separate those values, and that's all of the objectives that we have for you within this those color lab. Now to me it's one the most expressive design decisions that you'll make in the entire process of designing your site. It's one of the tasks in CSS that you need to actually have a real strategy for. So be sure to put in some time during the planning stages of your site, think about the colors that you are going to use, what they're going to communicate to your viewers and how that color is going to be used all the way throughout your site.

You are going to want to be consistent when you are using color, so developing some policies about your colors use within your site is a very important part of that design process. So one of the things I would recommend you to do with this lab, you can take it a little bit further, continue to play around the files in this lab, try out some of the gradients that we were working with earlier, introduce a brand-new color palette, go out to the site like Kuler or mix your own color palette together, swap out the colors within this particular site, and see how it affects the feel and the design of the site. Try out all the different colors syntaxes and see which one you prefer.

Color is just like any other aspect of your design. It's something you are going to want to experiment with, play around with and apply a great deal of thought before you go in and implement it within your site.
