Lab #16 CSS Variables

-
Lab #16 was titled "CSS Variables". What this implies is that within this webpage, you will be able to modify the values of CSS on a page like the spacing, blur and base color of an element. In this lab, you can experiment with these properties on an image.


In this lab, there are multiple properties you can modify on the image. You can use the sliders to adjust the spacing of the image (revealing more of the colored background), blurriness of the image, and the color of the base (background). In the screenshot above of my website, I clicked to modify the base color of the background and a color palette opened up. This demonstrates that you can really make the color of the base anything you want from RGB to hexadecimal. 

In order to create this page, in my HTML I had put many labels and inputs to collect user interaction data. The inputs include the sliders which work with the spacing and blurriness. As for the color input, I had kept a JavaScript variable as the color which would update each time it was changed. This applies to all of the properties, as if you modify something on the page using any of the sliders, or change the base color, it will immediately update the page to the corresponding change.

Web designers would need to know how to implement this mechanic in their websites to allow users to be flexible and creative with how they want to modify something. For example, using the color picking option in a logo making website would allow users to freely choose a color they want for their logo simply using JavaScript to modify the CSS variables. In addition, using sliders could be useful for making something transparent or modifying the size, etc. There is much that users could do with modifying their own elements, but it is up to the web designer to allow for them to access it.

WBL Workshop #6 Interview Skills

-
          WBL Workshop #6 was about testing our interviewing skills. First thing that happened was us entering the room without knowing that we were going to be interviewed. So as a student you could say some of us were surprised about it. There were different people interviewing students that took place during this workshop. Students were set at different "stations" of people who would interview you. I was a little confused at first about what the interview would be about and what job we were actually being interviewed for to represent a mock interview. Then I realized that a perfect job for the situation would be something revolving around being a web designer. When it was my turn to be interviewed I wasn't nervous because I had some pre-answers in my head for obvious answers.               During the interview I kept looking toward the top right, for no apparent reason. I feel like I should have been looking at the employe...

CTE Expo Reflection Journal

Image
     The objective of the CTE EXPO was to engage the freshmen into seeing what the Web Design Academy was made of and what were the benefits of joining. It was also to make their interests peak as they could be exposed to these special skills.  To prepare for the CTE EXPO I just ran through looking for my best business attire I possibly had because I knew how important this event was, During the actual event I grabbed freshmen attention by saying, "hello are you interested in learning more about the visual design part of the CTE academy?" I used that line pretty much all the time to get the attention of the freshmen who looked lost or confused. I think what went well was that most of the freshmen, all the ones I met with, had an interest in the subject because of the amount of questions they asked and how detailed their questions were. For next year's CTE EXPO it would be best to realign the table structure because the poster boards of the visual design class were in...

Lab #12 Reflection

-
This lab was fun to learn but a little difficult at first. If you were learning adobe illustrator for the first time and had to do something with it, you would have a lot of trouble if you weren't reading the tutorials or listening to them. At first for me personally it was a little hard trying to figure out what to do. I go to the lab pretty much every day on my free period. Lunch personally is boring for me. Let's get back on topic. I took my time to read the tutorial for adobe illustrator again and absorb what I read. I did the extra reading to scan what I needed to complete the lab and what skills were needed to complete it. Though I wish I can post my work here, I really can't due to the fact it is saved in a pdf file. At first the file was in an .ai file but since I had to submit it in for a grade it was transferred into a pdf file for viewing purposes. It was something we learned from reviewing adobe illustrator. Adobe illustrator wasn't that hard to learn. The b...
