I'm starting learning flask and I'm planning on makin a sorting algorithm visualizer using flask and I'm tryin to represent the elements of the array as bars (the height of the bars is = to the value of each element in the array). I'm thinking to use the display: block but it does not appear on the page. Pls help me or suggest anything if this is possible
html file:
<!DOCTYPE html>
<html>
<head>
<title>Sample</title>
<link rel="stylesheet" href="{{ url_for('static', filename='design.css') }}">
</head>
<body>
<div class="bar">
<p>test</p>
</div>
</body>
</html>
css file:
.bar{
display: inline-block;
height: 120px;
width: 5px;
background-color: red;
color: white;
}
this what only shows on my page. other css property works well this display: bar was the only problem
Normally this is an issue with browser caching. If you did not use a file and added it directly to <head> it should work
<head>
<style>
.bar{
display: inline-block; /*You want block or inline-block?*/
height: 120px;
width: 5px;
background-color: red;
color: white;
}
</style>
</head>
If you really want to use the css file, use versioning in the url:
/static/design.css/?v=1 next time /static/design.css/?v=2
But it becomes tedious. You can add a random variable like this:
import uuid
v = str(uuid.uuid4())
# url_for('static', filename='design.css', v=v)
Please clarify your answer using a screenshot of what is happening now

I have created a plotly graph in python and would like to display it on my HTML page. The problem is that the graph does not seem to fit the div propertly. Here is what I mean:
I would like it to scale based on the screen size to fit into the first column, but no matter what i do in iframe, the size of the graph itsesf remains constant. How can that be fixed?
P.S. I am unable to change the python code, so I am looking for the solution in HTML, but it would be interesting to hear how to fix this in the future in python
Here is the code for the page:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
* {
box-sizing: border-box;
}
/* Create two equal columns that floats next to each other */
.column {
float: left;
width: 50%;
padding: 10px;
height: 300px; /* Should be removed. Only for demonstration */
}
/* Clear floats after the columns */
.row:after {
content: "";
display: table;
clear: both;
}
</style>
</head>
<body>
<h2>Two Equal Columns</h2>
<div class="row">
<div class="column" style="background-color:#aaa;">
<iframe id="igraph" scrolling="no" style="display: block; width: 100%; height: 100%" seamless="seamless" src="report_graph_2.html"></iframe>
</div>
<div class="column" style="background-color:#bbb;">
<h2>Column 2</h2>
<p>Some text..</p>
</div>
</div>
</body>
</html>
And here is a full website if you need to see the code for the plotly graph.
I'm just learning how to use Django and HTML, and I encountered such a problem that my image is not displayed on the button, I don't understand what the error is and I will be grateful if someone can help me fix it
<!DOCTYPE html>
<html lang="ru">
<head>
<meta charset="utf-8">
<title></title>
<style>
button {
background-image: url("/main/static/main/img/i.jpg");
padding-left: 32px;
padding-top: 10px;
padding-bottom: 10px;
background-repeat: no-repeat;
width: 320px;
height: 320px;
}
</style>
</head>
<body>
<button></button>
</body>
</html>
<button>
<img src=path />
</button>
would be easy solution? It depends how do you want it to be displayed. As button and inside a image or just image which can be clicked on?
Your image path must exists somewhere where it can pull it from.
EDIT: If you have Firefox Web Browser you can probably see in console (by pressing F12 on keyboard) what's the error message help you identify the source of the problem. I tried your code with another path to image and it works just the image is not centered vertically nor horizontally

How to serve static files in Flask

Closed 1 year ago.
I have this application and I made an animation background and when I open the HTML in chrome so it works well but then when I run it with flask It doesn't add the background and just ignores it
It's probably something that I missed but I still can't understand why it doesn't load the background

Python:
from flask import Flask, render_template, request
def create_app():
app = Flask(__name__)
#app.route('/', methods=['POST', 'GET'])
def home():
return render_template("base.html")
return app
It's due to the server being unable to locate the style.css file. To fix this, make sure your static files are located inside a folder named 'static' next to your flask application python file. something like this:
/app
- app.py
/templates
- base.html
/static
- style.css
And to easily link the files in the templates using:
<link rel="stylesheet" href="{{ url_for('static',filename='style.css') }}">
Check Flask's docs for more details
Good luck :)
I'm trying to generate an HTML with the dominate package in Python. For the format, I have to add a short CSS content into the <style> tag. However, the only documentation I can find is the GitHub page and that page doesn't have any function related to adding the <style>.
PS: Here's an image
Is this what you are after? from here
import dominate
from dominate.tags import link, script, style
doc = dominate.document(title='Dominate your HTML')
with doc.head:
link(rel='stylesheet', href='style.css')
script(type='text/javascript', src='script.js')
style("""\
body {
background-color: #F9F8F1;
color: #2C232A;
font-family: sans-serif;
font-size: 2.6em;
margin: 3em 1em;
}
""")
print(doc.render(pretty=True))
It yields;
<!DOCTYPE html>
<html>
<head>
<title>Dominate your HTML</title>
<link href="style.css" rel="stylesheet">

Hoping someone may have solved this problem. Haven't seen anyone with it on Google.
I'm using xhtml2pdf in Python, trying to generate a simple document with a header, footer and my content is blocks of text with titles. I'd like to have a border around each piece of content but instead I get borders around each child element instead.
Here's my HTML
#page {
size: letter;
border: 0;
#frame header_frame {
-pdf-frame-content: header;
border: 0pt solid white;
left: .75in;
width: 7in;
top: .5in;
height: 1.5in;
}
#frame content_frame {
border: 0pt solid white;
left: .75in;
width: 7in;
top: 1.5in;
height: 7.5in;
}
#frame footer_frame {
-pdf-frame-content: footer;
border: 0pt solid white;
left: .75in;
width: 7in;
top: 9.5in;
height: 1in;
}
}
h1 {
padding-top: 5pt;
}
.desc {
margin-top: 3px;
margin-bottom: 3px;
padding: 3px;
border: 1px solid blue;
}

I'm just running the xhtml2pdf command line tool at the moment so there's no python to show. One thing I did notice when I run it in debug mode it shows "xhtml = false" even though I have an XHTML DTD. I'm not sure if this would make a difference.
Here's what I see in the browser and roughly what I expect the pdf to look like (ignoring the footer location of course):
Instead I get:
EDIT: I figured out that xhtml is an option to pass but passing it fails unless one has an old version of html5lib installed. Looks like the answer to my question is this library is not being actively maintained and I need to find a new solution :-/
