Here is an example implementation of the web page based on Python and Flask:

Python code (app.py):

from flask import Flask, render_template, request, jsonify

app = Flask(__name__)

@app.route('/')
def index():
    return render_template('index.html')

@app.route('/load_csv', methods=['POST'])
def load_csv():
    chapter = request.form.get('chapter')
    section = request.form.get('section')
    column = request.form.get('column')

    # Load the corresponding CSV file based on chapter and section
    csv_file = f'{chapter}_{section}.csv'
    # Read the CSV file and get the text data

    # Apply transparency to the selected column

    # Return the text data as JSON
    return jsonify({'data': text_data})

if __name__ == '__main__':
    app.run(debug=True)

HTML code (index.html):

<!DOCTYPE html>
<html>
<head>
    <title>Python Flask Web Page</title>
    <link rel="stylesheet" href="style.css">
    <script src="script.js"></script>
</head>
<body>
    <div class="container">
        <h1>Web Page</h1>
        <div class="form-group">
            <label for="chapter">Chapter:</label>
            <select id="chapter" name="chapter">
                <option value="1">Chapter 1</option>
                <option value="2">Chapter 2</option>
            </select>
        </div>
        <div class="form-group">
            <label for="section">Section:</label>
            <select id="section" name="section">
                <option value="1">Section 1</option>
                <option value="2">Section 2</option>
            </select>
        </div>
        <div class="form-group">
            <label for="column">Column:</label>
            <select id="column" name="column">
                <option value="even">Even</option>
                <option value="odd">Odd</option>
            </select>
        </div>
        <button id="load-btn" onclick="loadCSV()">Load</button>
        <div id="text-display"></div>
        <textarea id="input-text"></textarea>
        <button id="highlight-btn" onclick="highlightText()">Highlight</button>
        <button id="clear-btn" onclick="clearText()">Clear</button>
    </div>
</body>
</html>

CSS code (style.css):

.container {
    max-width: 600px;
    margin: 0 auto;
    padding: 20px;
}

.form-group {
    margin-bottom: 10px;
}

#text-display {
    margin-top: 20px;
    padding: 10px;
    border: 1px solid #ccc;
    min-height: 100px;
}

#input-text {
    margin-top: 10px;
    width: 100%;
    height: 200px;
}

button {
    margin-top: 10px;
}

JavaScript code (script.js):

function loadCSV() {
    var chapter = document.getElementById('chapter').value;
    var section = document.getElementById('section').value;
    var column = document.getElementById('column').value;

    // Make AJAX request to the Flask server to load the CSV
    // Use the returned data to update the text display area
}

function highlightText() {
    // Highlight the selected text in the text display area
    // Set a timeout to remove the highlight after 8 seconds
}

function clearText() {
    document.getElementById('text-display').innerHTML = '';
    document.getElementById('input-text').value = '';
}

Note: The implementation of reading the CSV file, applying transparency, and highlighting the text is not included in this example as it requires additional code specific to your use case.
