How to Center a Div in HTML and CSS?

 To center a `<div>` element in HTML and CSS, you can use a combination of CSS properties. Here's a common method to center a `<div>` both horizontally and vertically:


```html

<!DOCTYPE html>

<html>

<head>

<style>

  .centered-div {

    width: 200px; /* Adjust the width as needed */

    height: 200px; /* Adjust the height as needed */

    margin: 0 auto; /* Horizontally center the div */

    position: absolute;

    top: 50%; /* Vertically center the div */

    left: 50%;

    transform: translate(-50%, -50%); /* Move the div back by 50% of its own width and height */

    background-color: lightgray;

    text-align: center; /* Center text horizontally within the div */

    padding: 20px; /* Add some padding for better appearance */

  }

</style>

</head>

<body>

  <div class="centered-div">

    Content goes here

  </div>

</body>

</html>

```


In this code:


1. We create a `<div>` element with a class of "centered-div" for styling.


2. We set the `width` and `height` of the `<div>` to the desired dimensions.


3. `margin: 0 auto;` is used to horizontally center the `<div` in its parent container.


4. `position: absolute;`, `top: 50%;`, and `left: 50%;` are used to position the `<div>` in the vertical and horizontal center of the viewport.


5. `transform: translate(-50%, -50%);` is used to move the `<div>` back by 50% of its own width and height, effectively centering it both horizontally and vertically.


6. We set `background-color` to light gray for illustration purposes.


7. `text-align: center;` and `padding` are used to center text horizontally and add some spacing around the content within the `<div>`.


This method will center the `<div>` both horizontally and vertically within its parent container or the viewport, depending on the context. You can adjust the `width` and `height` values as well as other styles to fit your specific design requirements.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
