Is there an easy way of proofreading markup languagefor errors, or does the creator have to read throughevery character in the file any time there is a problem? Yes – it’s called ‘debugging,’ and there are tools to help with that. There are debugging tools built into your browser.
The reason I am almost laughing about it now is that it’sridiculous to me that even when one seems to follow allthe “rules” of coding or using a computer, sometimesinexplicable things come up that completely disrupt ornegate all your work. As much as we know about andunderstand computers, we don’t always have rhyme orreason for why computers do what they do.Three engineers were aboard a stopped train …
Will there ever be an easier way to create digitaldocuments? Yes: blogs and wikis, for example, make page creation easy. But if you want to process lots of source data, or create HTML pages on- the-fly, you need to know the code.
I find that as we delve into more complex programminglanguages, I am having a harder time grasping thenecessary steps. Should this be the case? YES.
Would it not be easier to control the structure, style, andbehavior of a web page with one markup language, inone file?What was the motivation for having all of these weblanguages interact with each other?It would be nice, but this is kind of like wishinghumans had one language. The web is a vast,evolving system, and these languages were createdat different times to solve different problems.One reason they are separated is because different people do the coding for each layer.
I don’t understand how we can insert a new languageinto HTML using a new tag in the header, without itbeing a part of the HTML?HTML is a source code that can hold lots ofdifferent content, including programming code.But the code and the content are treateddifferently by the browser in producing theresulting page that you see.
