Theme development

Hello,

I am using the following code to alter a form:

Hello,

I have a news website and I want to print the node's page each time in a different way depending on a field value.

The problem

I have a content type named "Article" in the article there are a number of fields that are going to be visible/invisible depending on a field called "Theme" (Conditional fields) also the "Theme" field is responsible to determine the twig that is going to be used.

Hello everybody, please i need to hide by css ''Files must be less than 20 MB.'' in creating node page

How can I adapt this theme to use a sticky footer? Apart from that, if I don't use a footer, how can one make this theme have pages take up 100% of the browser page height when the content is smaller? I have some css overrides, but I am so far unable to work out what to set. Have tried height = 100% on body and #main-container and other things I think are wrappers, to no avail.

I have a question, I would like to have a list functionality on my website like the one in this page p2p lending sites Does anyone know an extension to do it?

Hello,
