Winform C# Application, how do I align text inside a button?

I would like to create a button with a plus sign, however when I created the plus sign with the text, it is not aligned from the top of the button as in the image below:
The problem occurs when I try to increase the font size. In default size of the text the plus sign is centered. What can I do to center it in my case?
TextAlign (TopLeft) and UseCompatibleTextRendering didn't work. (Winforms C# Visual Studio 2019)
Note: Text align property did not work because my font size is larger than default it is 36+.

You can use an png of + from resource instead of setting directly the text property of the button.
Example
this.button1.Image = NameSpace1.Properties.Resources.Image2.png;

One way is to set the Button's FlatStyle (https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.buttonbase.flatstyle?view=net-5.0) to System (System.Windows.Forms.FlatStyle.System), if you are Ok to change the FlatStyle.

I created a test application and the combination of font "Microsoft Sans Serif" in size 36pt with button size 32x32px and FlatStyle = FlatStyle.System (as elimad already mentioned) works quite well for me.
namespace ControlTest
{
public class MainForm : Form
{
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.Run(new MainForm());
}
private Button button1;
public MainForm()
{
InitializeComponent();
}
private void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
this.SuspendLayout();
//
// button1
//
this.button1.FlatStyle = System.Windows.Forms.FlatStyle.System;
this.button1.Font = new System.Drawing.Font("Microsoft Sans Serif", 36F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
this.button1.Location = new System.Drawing.Point(16, 16);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(32, 32);
this.button1.TabIndex = 0;
this.button1.Text = "+";
//
// MainForm
//
this.ClientSize = new System.Drawing.Size(157, 92);
this.Controls.Add(this.button1);
this.Name = "MainForm";
this.Text = "ControlTest";
this.ResumeLayout(false);
}
}
}

You can create custom controls and then render the text yourself

After compiling it should just show up inside the toolbox

Margin is not being applied

I have a user control that I need to manually resize during runtime, although I would like the margin to be applied. I found, from link 1 below, that for the margin to work the AutoSize property needs to be set to true. Although, since I need to manually resize the control during runtime, the AutoSize property needs to be false to my understanding.
The user control (Accordion) contains a horizontal split panel where the first panel contains a button and the second panel contains a Panel control. In the image below you can see multiple "Accordions" which, in the picture, is one of the buttons. The Accordions are docked at the top of the container. The intent is when I click on the button it resizes and shows the "contents panel" and the contents panel's control. My problem is that setting the User Control's margin property does not cause them to automatically distance themselves from the other controls nor the container they are in.

Hopefully some useful chunks of what I'm working with.

Not sure I completely understood your problem but maybe this can be of help. If you want a fixed margin to stay around your control after a resize (due to the SplitContainer panel extending/collapsing), you can try this:
on your blank user control drag a Panel control and set its Margin to (0,0,0,0) and Padding to (x,x,x,x), where x is the width of the margin you want.
Be careful when doing calculations on the height of the children controls to resize the control, always take the paddings and margins into account if you have them set on some children.
UPDATE:
As stated here: https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.control.margin?view=netframework-4.8
"Setting the Margin property on a docked control has no effect on the distance of the control from the edges of its container."
So, I think you have to choose a specific container like TableLayoutPanel or a FlowLayoutPanel. Try with a FlowLayoutPanel and set it like this:
AutoSize = true;
BorderStyle = FixedSingle (just to see if the margin is kept correctly)
FlowDirection = TopDown
Then drag inside of it some of your controls with the AutoSize property set to false and with the Margin set as you prefer. You should get something like this:
Note: the height of your controls may still be changed (maybe setting a minimum control height can be of help), but once you set their width, the FlowLayoutPanel control can't cut the control because of the margin.

Define style for all labels

I'm working in a c# application in winform.
I saw that there is no Style for element (unlike WPF). But is there a way to simply set all the labels to a specific design ?
Actually I do :
public partial class myControl : UserControl
{
private Color LabelColor = Color.Indigo;
private Color LabelFont = new System.Drawing.Font("Arial",
18F,
System.Drawing.FontStyle.Regular,
System.Drawing.GraphicsUnit.Point,
((byte)(0)));
public myControl()
{
InitializeComponent();
//Set design
designLabels();
}
private void designLabels()
{
List<Label> labelsToStyle = new List<Label>();
labelsToStyle.Add(labelName);
labelsToStyle.Add(labelAge);
labelsToStyle.Add(labelSize);
foreach (Label l in labelsToStyle)
{
l.ForeColor = LabelColor;
l.Font = LabelFont;
l.Dock = DockStyle.Fill;
}
}
}
It works but it doesn't display correctly in designer (I have to run application to see my design). And maybe it exists a simplest way ?

As per my comment the easiest is to create a custom control and use that one in your windows.
here how simple it is. Simply override the label and set in constructor the default value you want
public class DesignLabel : Label
{
public DesignLabel()
{
ForeColor = Color.Indigo;
Font = new System.Drawing.Font("Arial", 18F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
}
}
then compile once and go to your design view, open your toolbox and you will see the "DesignLabel", simply drag drop on the window and that's it. If you change default in the class it will be changed all over the place.

If you want to change the style already at design time so that you can see in in the Form.cs[design] you need to edit the Form.Designer.cs file! But this you have to do label for label by hand. I saved in this example the Font and Color in the project properties (sorry for the german version):
in my example I have 3 Labels. In the Form.Designer.cs file you can add the properties:
// label1
//
this.label1.AutoSize = true;
this.label1.Location = new System.Drawing.Point(12, 9);
this.label1.Name = "label1";
this.label1.Size = new System.Drawing.Size(41, 15);
this.label1.TabIndex = 0;
this.label1.Text = "label1";
this.label1.Font = Properties.Settings.Default.LabelFont;
this.label1.ForeColor = Properties.Settings.Default.LabelColor;
//
// label2
//
this.label2.AutoSize = true;
this.label2.Location = new System.Drawing.Point(12, 68);
this.label2.Name = "label2";
this.label2.Size = new System.Drawing.Size(41, 15);
this.label2.TabIndex = 1;
this.label2.Text = "label2";
this.label2.Font = Properties.Settings.Default.LabelFont;
this.label2.ForeColor = Properties.Settings.Default.LabelColor;
//
// label3
//
this.label3.AutoSize = true;
this.label3.Location = new System.Drawing.Point(12, 122);
this.label3.Name = "label3";
this.label3.Size = new System.Drawing.Size(41, 15);
this.label3.TabIndex = 2;
this.label3.Text = "label3";
this.label3.Font = Properties.Settings.Default.LabelFont;
this.label3.ForeColor = Properties.Settings.Default.LabelColor;
The result looks like this:
DISCLAIMER
I would not recommend this approach! Editing the Form.Desginer.cs file is never a good idea! I would stick to the run time changes. If you want to change all Labels just filter the this.Controls for it and foreach through the collection like this:
this.Controls.OfType<Label>().ToList().ForEach(lbl =>
{
lbl.Font = LabelFont;
lbl.ForeColor = LabelColor;
//lbl.Dock = DockStyle.Fill; // uncommented, because I could see only 1 Label
});
The result will be the same.

You can see my custom control overflows form size.
Note: Flow layout panel used in the picture has a dock fill, flow direction = top down & wrap contents = false.
Can anyone please suggest?

Using the custom label class from this page for the message label inside panel as suggested by #Reza Aghaei did the job. See the result below, this is exactly what I wanted.

WebBrowser (win form) opacity

I have a system windows forms web browser on top of another control. The web browser has an image set.
On top of the web browser control is an inherited panel where I can control the opacity.
If I make this transparent, it doesn't show the web browser image, it shows the back colour of the control under the web browser.
Ie
Layer1 control. Back colour is blue
Layer2 web browser with image as HTML
Layer3 transparent panel
Layer3 when transparent shows layer1 not layer2
How can I make the web browser opaque so layer3 shows through to layer2 (webbrowser) ?
I have tried setting SetStyles to control opacity on the web browser.
Thanks

Short Answer:
You can't.
Real World Solution:
Have you looked into WPF?
Long Answer:
Opacity is a trick that WinForms does.
When a control is marked to be displayed transparent (or semi transparent), WinForms queries the parent object's visuals to ask "What would you have printed here had my control not existed?". From this result WinForms either displays the pixel of the control, the pixel of the parent, or a combination of the two (if semi transparent).
This becomes really apparent in a simple example:
Create a new winforms project
Create 2 labels, place them over top of each other (slighty offset)
Set both labels backgrounds to Color.Transparent
You'll see immediately that transparency takes a chunk out of the label underneath.
