JavaScript : What Is It Anyway?

  This programming language is awesome to learn because it lets you create interactive and dynamic features on websites.    You can have pop-up messages, clicks, update content, and so much more.  JavaScript helps to bring the HTML and CSS markup language come alive through different types of action. It's easier to think of JavaScript like this: If HTML is like a noun and CSS is like an adjective that is describing the noun (like having the font be blue and the background page be yellow), then JavaScript is the verb that makes your webpage have some sort of action.  So next time you forget what JavaScript is all about, just think of what kind of word verbs are.  They are action words and JavaScript helps you to take that action. Stay tuned as I continue to learn all about this programming language.

Back To The Basics

It's Been A LOOONG Minute since I have coded!!   Even so, I decided to give JavaScript another try.  I always seem to do good and then when I get to this one area, I always seem to hit a brick wall.  Well....nothing like getting back up and trying again right?   I decided to try:  The Complete JavaScript Course 2025: From Zero to Expert! by Jonas Schmedtmann.   So far, he seems to explain things in a way my brain understands it.  šŸ’ To let you know how much I have forgotten in the coding world, I couldn't even remember how to write the basic commands for an HTML document! Yesterday I started the fundamentals free course and I am so glad that I did.  Because of time, I only made it through the JavaScript History and Setup chapter, but that chapter was enough to get my memory flowing again!   It started to feel familiar and I quickly remembered why I enjoyed coding so much.  Yesterday and this morning, I just erased and...

ATTRIBUTES in HTML

ATTRIBUTES:  ADDITIONAL INFORMATION ABOUT AN ELEMENT Sometimes we have HTML elements that need to have more defined information about them.  Enter " Attributes ".   Think of an HTML attribute like an adjective or an adverb.  Adjectives and adverbs describe the noun/verb.  It gives additional information.  Attributes work in a very similar way.  They give additional information about the element. Attributes are always specified in the start tag. Please take a look at the two photos below: (a) (b) In the first picture (a), you see the HTML code for the web site.  If you look at the < h1 > tag (located under the < body > tag), you see that it is the element tag for a header.   The contents in between the opening and closing < h1 > tags says "Hello World!". The picture (b) it shows how the website renders.  "HELLO WORLD!" is in a large font (because it is a header) in the default text ...

BASIC HTML Body Elements That Help Make A Web Page Look The Way It Does

BODY ELEMENTS ?! Everyone has a body, and each body looks different.  The same goes for web pages.  Today we are going to talk about the basic body elements that is needed in the HTML code as well as a couple of some basic style elements. ROOT ELEMENT What is a root element? A root element is the sole parent element to all other elements in the document.  What this means is that every other element within the HTML document is going to be either a child or a grandchild of the root element.  Remember in my previous post, that HTML documents are structured like a tree .  Every tree has roots and a trunk.  Think of the root element as the trunk.  For HTML, that root element opening tag will always look like this:  <html> .  The </html> closing tag will be at the end.  Please see the picture below: HTML ELEMENTS START AND END/CLOSING TAGS :  Most  HTML elements have a start tag and an end tag with the ...

XPATH and XPATH Expressions In XMLLINT

XPATH And XPATH Expressions Earlier, I told you about xmllint and xmllint for html files .  Let's say you just want to parse the <span> tags within your html file or just your <span lang="el"> tags? Enter:  Xpath. Xpath is yet another option available within the xmllint language. Remember, an Xpath is used to navigate through elements and attributes in xml and html documents.  Xpath uses Xpath Expressions to select nodes or node sets within a document. Example 1 .  Looking for all of the <span> tags within an html document. xmllint -- html -- xpath " // span" StedmanLesson10.html xmllint = This tells the command line that we are going to be using the xmllint language. space = because we always have space in between commands -- = Remember, these are the two hyphen-minus characters that we need to tell the command line that we are going to use an xmllint option. html = This is the xmllint option we want to ...

XMLLINT for HTML: Cleaning up the HTML Code

Getting That MESS Cleaned Up! In an earlier post, we learned about xmllint .  Today, I want to talk about cleaning up the code for an HTML file. When we have an xml file, xmllint is used.  For an html file, we use the following command in the command line: xmllint --html <filename goes here>         Here is an actual command on my command line for running xmllint for my StedmanLesson10.html file. In the photo above, you see that I start off the command with xmllint. The next thing is a space and then a --html.  The two -- are two hyphen-minus characters that are used to specify long options (Basically there are options that can be used within xmllint.  The two hyphen-minus characters are saying an option is going to be used.  In this case, that option will be html - because we are going to do an xmllint on an html file). After that you see a space and then the name of the html file I want t...
