Creating a WordPress theme using Ctrl+C, Ctrl+V, and what are the consequences of this approach?

Question

Freelance

A bit of background, I made sites on ModX Evo, but faced with the categorical desire of some people to have a site on WordPress, with their layout and other things, I thought about it, decided to pull it up a little and turned to tutsplus, which talks about child themes, syntax and other things.
But today I came across a video of Wordpress integration of layout in 12 minutes,
if we briefly take a WP theme template, insert HTML code, insert a couple of PHP injections like: <?php wp_nav_menu('prymary') ?> , and everything "works".
Now the questions are:
1) What are the disadvantages in this approach if the result is at the moment! delivery satisfies the customer
2) Is it worth bothering more and further?

Answer 1

If done strictly according to the video. It will work, but nothing more.
But with this approach, most plugins will not start, and if you add wp_head, there will be conflicts.
An ordinary blog, from a normal layout, if Api reaches WP in 1-2 hours.
In the video, by the way, he pulled 1 template in like 12 minutes, what he did, in this form, is done in 3 minutes.

Answer 2

the main thing is that this is wp_headeralso wp_footernecessary for the adequate performance of different plugins. And so if you are not interested in WordPress

satisfies the customer

Answer 3

The approach is fundamentally wrong.
The theme loses the ability to update / when updating everything will break. This is at least. And as a result - holes and hacking.
The mechanism of child themes was just invented for customizing themes. And this is no more difficult than the wrong approach.

Answer 4

It surprises me when they say that WP is copy-paste and not programming. If a person says so, then he has not met a senior on WP. As for the question, this is bad, try to write everything by hand and only more pieces can be copied and pasted, I think.

Answer 5

Check out this channel. There is a video on how both the html template is stretched and how the PSD template is stretched. And it certainly won't take 12 minutes.
