In drupal, when you have ajax refreshing some content, elements get new ids when they refresh. So some input element that was "edit-get-score"  becomes "edit-get-score-2" then ""edit-get-score-3" etc.
So to match them properly by ID you can use this. Which is CSS attribute selector using sort of a wildcard

It is said here in docs api you can add JS file to some other region then header of footer https://api.drupal.org/api/drupal/includes%21common.inc/function/drupal…
To to that you need to assign it to that region but also add it in html/page preprocess

When changing weight of element in array, it is not enough to just change weight, #sorted must be set to FALSE so elements are resorted.

$variables['form']['element']['#weight'] = -10;
$variables['form']['element']['#sorted'] = FALSE;

Recently I got to fix some older Drupal 6 site.

As subject tries do describe, to build cool login screens that are popular now and you can find them on sites such as
https://www.icloud.com/ and https://app.buzzsumo.com/login you need to remove all the data from a page and just have content.

Node edit forms are not the nicest thing you have seen and new layouts in Drupal 8 that basically copies wordpress style forms are much better. Sometimes you will have clients that can't stand this vertical tabs and would rather not have them at all and probably they will never use them anyway. So best thing to do is to remove them for them.

So I am overriding the login form and want to have unique state of the form for the first load screen, when user hasn't entered anything yet. What do I do, I tried to get what is the difference with form vars when submitted and when never submitted. I found out you can do this by form ID as it changes each time (which is not so good for theming of the forms).

There is a good guide how to make custom login here https://www.drupal.org/node/350634

I know Sass and Less are major improvements in Css coding, but setting all this up is a drag. I was using Omega 4 and to style it we need to use Sass coding. There are enough resources out there, but they are often limited to some special use case scenario and as there are many components to make it work you will have problems when trying to set it up.

So this is some marketing stuff I do, but it is useful. When you click a link on some site, to give some message to that site and owner or whoevere is taking care of marketing you can add some UTM tags to links so in their google analytics they see that message. So what do we do is I use display suite, create custom code field and use entity data to make new fields that look like this:
