Adding scroll to the final output view using ipywidgets

I am trying to create an app based on ipywidgets. But unfortunately the scroll is not appearing as I expect it to be. Instead the scrolls are appearing on every output element, whereas I want a single scroll if the height of the content in any of the output element exceeds. Moreover it should not cut the visibility of the content in any of the output.
%%html
<style>
.out1{
width: 700px;
height: 400px;
display: flex;
justify-content: center;
padding: 10px 10px 10px 10px;
border: 1px solid black;
}
.out2{
width: 350px;
height: 400px;
display: flex;
justify-content: center;
padding: 20px 5px 10px 10px;
border: 1px solid black;
}
.out3{
width: 350px;
height: 400px;
display: flex;
justify-content: center;
padding: 20px 5px 10px 10px;
border: 1px solid black;
}
.out4{
width: 700px;
height: 400px;
display: flex;
justify-content: center;
padding: 20px 10px 0px 10px;
border: 1px solid black;
}
.out_box{
border: 1px solid black;
height: 800px;
width: 700px;
overflow: auto;
}
</style>
out1=widgets.Output()
out1.add_class('out1')
out2=widgets.Output()
out2.add_class('out2')
out3=widgets.Output()
out3.add_class('out3')
out4=widgets.Output()
out4.add_class('out4')
box1=widgets.Box([out1], scroll=False)
box2=widgets.HBox([out2,out3], scroll=False)
box3=widgets.Box([out4], scroll=False)
out_box=widgets.VBox([box1,box2,box3])
out_box.add_class('out_box')
Attached is the snap, which I am getting. Results with multiple scroll bars. But I want a single scroll bar at the right end.

How to use css's :after for widgets in pyqt

I am thinking to create a PyQt6 Application.
I want that application to be more beautiful and modern. So I found some good looking css buttons and chose this codepen button:
* {
margin: 0;
padding: 0;
}
html,
body {
box-sizing: border-box;
height: 100%;
width: 100%;
}
body {
background: #FFF;
font-family: 'Noto Sans JP', sans-serif;
font-weight: 400;
}
.buttons {
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content: center;
text-align: center;
width: 100%;
height: 100%;
margin: 0 auto;
/* padding: 2em 0em; */
}
.container {
align-items: center;
display: flex;
flex-direction: column;
justify-content: center;
text-align: center;
background-color: #FFF;
padding: 40px 0px;
width: 240px;
}
h1 {
text-align: left;

font-size: 1em;
}
p {
text-align: left;

letter-spacing: 0.05em;
font-size: 0.8em;
margin: 0 0 2em;
}
.btn {
letter-spacing: 0.1em;
cursor: pointer;
font-size: 14px;
font-weight: 400;
line-height: 45px;
max-width: 160px;

My question is: how can I use pyqt's functions to perform the :after.
I guess I cant just use a widget's stylesheet to perform.
Here is the Python Code that I have written so far:
from PyQt6.QtCore import QRect, Qt
from PyQt6.QtGui import QEnterEvent
from PyQt6.QtWidgets import QGraphicsOpacityEffect, QMainWindow, QPushButton
class QButton(QPushButton):
def __init__(self , main_window: QMainWindow):
super().__init__(main_window)
self.main_window = main_window
self.setText("Welcome")
self.render()
def render(self):
self.setStyleSheet("""
QPushButton{
background-color: #2E3440;
letter-spacing: 0.1px;
font-size: 14px;
font-weight: 400;
line-height: 45px;
text-decoration: none;
color: #FFF;
border: 4px solid #4C566A;
}
""")
self.setFlat(True)
self.setCursor(Qt.CursorShape.PointingHandCursor)
self.setGeometry(QRect(200 , 200 , 200 , 50))
def setText(self , text: str):
text = text.upper()
super().setText(text)
def enterEvent(self, event: QEnterEvent) -> None:
self.setStyleSheet("""
background-color: #D8DEE9;
letter-spacing: 0.13em;
color: #2E3440;
border: 0px;
""")
opacity = QGraphicsOpacityEffect()
opacity.setOpacity(.8)
self.setGraphicsEffect(opacity)
return super().enterEvent(event)
class Renderer:
def __init__(self, main_window: QMainWindow) -> None:
self.main_window = main_window
def render(self):
button = QButton(self.main_window)
if __name__ == "__main__":
app = QApplication([])
window = QMainWindow()
renderer = Renderer(window)
renderer.render()
window.show()
exit(app.exec())

Unfortunately, you can't. Qt Style Sheets are fundamentally based on CSS 2.1, and only support its basic implementation (see the syntax documentation).
If you want a more customized and advanced behavior, you have only two options:
subclass the widget and/or use QProxyStyle;
use QML;

I don't know AttributeError: 'NoneType' object has no attribute 'send_keys' in python selenium. I tried all solutions but still problem

There is an Attribution problem. I tried all references but I can't fix it.
This code is only successful when the cursor is on the textbox.
code:
browser.get('https://zeus.gist.ac.kr/sys/main/main.do')
browser.implicitly_wait(10)
iframe = browser.find_element_by_id("TOBE_JSP")
browser.switch_to.frame(iframe)
browser.find_element_by_id('mainframe_VFrameSet_HFrameSet_leftFrame_form_gridMenu_body_gridrow_7').click()
browser.implicitly_wait(10)
browser.find_element_by_id('mainframe_VFrameSet_HFrameSet_leftFrame_form_gridMenu_body_gridrow_12').click()
browser.implicitly_wait(10)
bodytemp = browser.find_element_by_xpath("~~~~/input").click()
bodytemp.send_keys("36.5")
element:
<div id="~~~~" style="position: absolute; overflow: hidden; background-color: transparent; left: 0px; top: 0px; width: 54px; height: 18px; cursor: text; user-select: initial;"><input id="mainframe_VFrameSet_HFrameSet_MDIFrameSet_ctxFrameSet_ctxFrame_PERS07^PERS07_08^005^AmcDailyTempRegE_form_div_sample_divMain_divForm_edtTemp_input" tabindex="-1" style="border: none; outline: none; position: absolute; overflow: hidden; background-color: transparent; left: 0px; top: 0px; width: 54px; height: 18px; cursor: text; font: 9pt NanumGothic; color: rgb(34, 34, 34); text-align: left; padding: 0px 1px;"></div>
<input id="~~~~_input" tabindex="-1" style="border: none; outline: none; position: absolute; overflow: hidden; background-color: transparent; left: 0px; top: 0px; width: 54px; height: 18px; cursor: text; font: 9pt NanumGothic; color: rgb(34, 34, 34); text-align: left; padding: 0px 1px;">
And I also tried:
bodytemp = browser.find_element_by_xpath("~~~~/input")
bodytemp.send_keys("36.5")
->selenium.common.exceptions.ElementNotInteractableException: Message: element not interactable
(Session info: chrome=89.0.4389.114)
It sometimes runs well(maybe 1/10..?)
And I also tried:
bodytemp = browser.find_element_by_xpath("~~~~/input")
bodytemp.clear()
bodytemp.send_keys("36.5")
-> AttributeError: 'NoneType' object has no attribute 'clear'
The element is visible. I already check it.
please help me. I can't sleep.

I just solve it to click and send_keys both.
browser.find_element_by_xpath("~~~~_input").click()
browser.find_element_by_xpath("~~~~_input").send_keys("36.5")

I need a div to be pushed down when several options from a dcc.dropdown menu have been selected (dash component, python)

I am having trouble making the div below the 'multi' dropdown (dcc.dropdown from dash) to be pushed down when several options from the menu have been selected instead of overlapping as in the image below (or be sent to the back depending on the z-index). The dropdown is inside another div. I´ve tried changing css display and position with no positive outcome yet.
The code looks something like this:
html.Div([
html.Div(children=html.H2('SIMILAR PLAYERS', className='titulo_ventanah2'), className='titulo_ventana'),
html.Div(children=[(html.I(className='search')),'Search by:'],style={'display':'inline-block','padding-left':'15%', 'font-size':'13px'}),
html.Div(children=(dcc.Dropdown(style={'height':'20px', 'font-size':'14px'},persistence_type='session')),style={'display':'inline-block', 'padding':'0px 0px 0px 10px', 'width':'200px', 'margin-top':'5px'}),
html.Div(children=(dcc.Dropdown(multi=True,style={'height':'20px', 'font-size':'14px'})),style={'padding':'0px 0px 0px 10px', 'width':'400px', 'margin-top':'5px'}, className='similardiv'),
html.Div([
html.Div(children=[html.Div(html.H3('Top 15 most similar players',className='titulo_ventanah3'),className='titulo_ventanaint'),
html.Hr(),
html.Div([children=dcc.Graph())])],className='similar_players'),
])
],className='container1')
There is also CSS code for some components:
.container1 {
position: fixed;
width:80%;
height:100%;
display:inline-block;
left:20%;
margin: 0 auto;
padding: 0 0px;
box-sizing: border-box;
overflow: hidden;
top:0;
overflow:auto;
background-color: #f5f5f5;
}
.titulo_ventana {
top:0;
display:inline-block;
background-color: #f5f5f5;
padding-left:2%;
margin: 0px 0px 0px 0px;
}
.titulo_ventanah2 {
text-decoration: none;
font-size: 20px;
line-height:45px;
color: #8f8f8f;
margin: 0px 0px 0px 0px;
display: inline-block;
letter-spacing: 0.01em;
}
.titulo_ventanaint {
overflow: hidden;
z-index:5;
height:39px;
display:inline-block;
background-color: white;
}
.titulo_ventanah3 {
max-width:100%;
text-decoration: none;
font-size: 14px;
color: black;
line-height:45px;
margin: 0px 0px 0px 0px;
padding: 0px 0px 0px 10px;
text-align: left;
overflow:hidden;
letter-spacing: 0.01em;
}
.similar_players {
width: 97%;
overflow: auto;
height:540px;
font-size: 15px;
color: #002e5c;
background-color: white;
margin-top:1.5%;
margin-left:1.5%;
display: block;
position:relative;
z-index:1;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}
.similardiv {
position:relative;
z-index:2;
display:inline-block;
}
I am hoping the solution is with a change in the display or position property of an element but I believe it has something to do with the default css for the dash component which can be found here.
You can check out the dashboard in link
If I change the position of the .Select-menu-outer to relative as suggested by CBroe in the comments, the following will happen only when the menu is opened:

The problem was to set the height of the dcc.Dropdown to 20px, by just deleting 'height':'20px' the problem got solved

How to handle this alert or frame using python selenium?

https://niioa.immigration.gov.tw/NIA_OnlineApply_inter/visafreeApply/visafreeApplyForm.action
Something pop up after I select the first item and I cannot handle the popup . I do not know what it is, it's not alert. and I cant find the frame for the (switch to frame)
its a Chinese website....
so I have pasted the elements that's loaded after I selected the first item
<div class="blockUI" style="display:none"></div>
<div class="blockUI blockOverlay" style="z-index: 1000; border: none; margin: 0px; padding: 0px; width: 100%; height: 100%; top: 0px; left: 0px; background-color: rgb(0, 0, 0); opacity: 0.6; cursor: wait; position: fixed;"></div>
<div class="blockUI blockMsg blockPage" style="z-index: 1011; position: fixed; padding: 0px; margin: 0px; width: 450px; top: 539.5px; left: 119.5px; text-align: center; color: rgb(0, 0, 0); border: 3px solid rgb(170, 170, 170); background-color: rgb(255, 255, 255); height: 140px; overflow: hidden;"><div id="showWarnMessage1" style="">
<table class="application" style="margin: 10px;">
<tbody><tr>
<td>
<p class="Prompt" style="text-align: center">注意</p>
<p>除香港居民持有BNO護照及澳門居民持有1999年前取得之葡萄牙護照外，持有外國護照，不適合辦理本許可。</p>
</td>
</tr>
</tbody></table>
<div>
<input class="btn" value="確認" type="button" onclick="$.unblockUI();">
</div>
</div></div>

This worked for me to get past the pop-up:
chromedriver = "your_path"
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(chromedriver)
driver.implicitly_wait(15)
driver.get('https://niioa.immigration.gov.tw/NIA_OnlineApply_inter/visafreeApply/visafreeApplyForm.action')
driver.find_element_by_xpath('//*[#id="isHKMOVisaN"]').click()
And then this last line is what gets rid of the pop-up:
driver.find_element_by_xpath('//*[#id="showWarnMessage1"]/div/input').click()
