[Solved] Help with CSS

@asti I did that.

  But it still didn't change the button's font and the comment's font. You can see in the screenshot. I cleaned cache.

@shira1,

Put this code as well:

#wpdcom .ql-editor > * { font-family: "Assistant", Sans-serif !important;}

@asti The comment's font has changed!!! But the button's font did not, how to change the button's font to Assistant? I also want that the comment's content will be black (#2B2B2B)

@shira1,

You should write the CSS code like this:

#wpdcom .wpd-second-button, #wpdcom .wpd-prim-button {
   font-family: "Assistant", Sans-serif !important;
}

I also want that the comment's content will be black (#2B2B2B)

Change the value of the "Comment Text". It's located in the Dashboard > wpDiscuz > Settings > Styles & Colors admin page

@asti it worked!!

I have two more questions:

1. How can I place the button below the field of the email?

2. How can I increase the font size? (I want it to grow in all the plugin's text (in the comment text, the button,the written comments ...)

@shira1,

1. How can I place the button below the field of the email?

Navigate to Dashboard > wpDiscuz > Forms admin page, edit the default form, find the "COMMENT TEXT FIELD" section, drag and drop the fields as you like. 

2. How can I increase the font size? (I want it to grow in all the plugin's text (in the comment text, the button,the written comments ...)

Please note, that we don't provide support for style customization, we may help in 1-2 simple questions related to colours and background but not more. We can not help you customize all components of website style, these are custom requirements and should be done by website owners. We only help with general questions and issues.

Thank you for your understanding.

You can find all classes by pressing F12 on the browser and opening Chrome or Firefox Console, it'll help you easily write CSS rules you need to customize.

@asti I'm sorry. I will not ask you anymore. 

I draged and droped the fields and now the button is in the left side, how can I straighten it to the right?

@shira1,

Just move all fields to the right.  

@asti All of them are on the right side:

@shira1,

Then, move them to left.  

@asti Now all the fields are on the left side. Never mind, I will leave it like the it was before
