How to connect css to html django

CSS – make it pretty!

Our blog still looks pretty ugly, right? Time to make it nice! We will use CSS for that.

What is CSS?

Cascading Style Sheets (CSS) is a language used for describing the look and formatting of a website written in a markup language (like HTML). Treat it as make-up for our web page. 😉

But we don’t want to start from scratch again, right? Once more, we’ll use something that programmers released on the Internet for free. Reinventing the wheel is no fun, you know.

Let’s use Bootstrap!

Bootstrap is one of the most popular HTML and CSS frameworks for developing beautiful websites: https://getbootstrap.com/

It was written by programmers who worked for Twitter. Now it’s developed by volunteers from all over the world!

Install Bootstrap

To install Bootstrap, open up your .html file in the code editor and add this to the section:

link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3" crossorigin="anonymous"> 

This doesn’t add any files to your project. It just points to files that exist on the Internet. So go ahead, open your website and refresh the page. Here it is!

Static files in Django

Finally we will take a closer look at these things we’ve been calling static files. Static files are all your CSS and images. Their content doesn’t depend on the request context and will be the same for every user.

Where to put static files for Django

Django already knows where to find the static files for the built-in «admin» app. Now we need to add some static files for our own app, blog .

We do that by creating a folder called static inside the blog app:

djangogirls ├── blog │ ├── migrations │ ├── static │ └── templates └── mysite 

Django will automatically find any folders called «static» inside any of your apps’ folders. Then it will be able to use their contents as static files.

Your first CSS file!

Let’s create a CSS file now, to add your own style to your web page. Create a new directory called css inside your static directory. Then create a new file called blog.css inside this css directory. Ready?

djangogirls └─── blog └─── static └─── css └─── blog.css 

Time to write some CSS! Open up the blog/static/css/blog.css file in your code editor.

We won’t be going too deep into customizing and learning about CSS here. There is a recommendation for a free CSS course at the end of this page if you would like to learn more.

But let’s do at least a little. Maybe we could change the color of our headers? To understand colors, computers use special codes. These codes start with # followed by 6 letters (A–F) and numbers (0–9). For example, the code for blue is #0000FF . You can find the color codes for many colors here: http://www.colorpicker.com/. You may also use predefined colors, such as red and green .

In your blog/static/css/blog.css file you should add the following code:

h1 a is a CSS Selector. This means we’re applying our styles to any a element inside of an h1 element; the h2 a selector does the same thing for h2 elements. So when we have something like

link

, the h1 a style will apply. In this case, we’re telling it to change its color to #C25100 , which is a dark orange. Or you can put your own color here, but make sure it has good contrast against a white background!

In a CSS file we determine styles for elements in the HTML file. The first way we identify elements is with the element name. You might remember these as tags from the HTML section. Things like a , h1 , and body are all examples of element names. We also identify elements by the attribute class or the attribute id . Class and id are names you give the element by yourself. Classes define groups of elements, and ids point to specific elements. For example, you could identify the following element by using the element name a , the class external_link , or the id link_to_wiki_page :

a href="https://en.wikipedia.org/wiki/Django" class="external_link" id="link_to_wiki_page"> 

We also need to tell our HTML template that we added some CSS. Open the blog/templates/blog/post_list.html file in the code editor and add this line at the very beginning of it:

We’re just loading static files here. 🙂 Between the and tags, after the links to the Bootstrap CSS files, add this line:

The browser reads the files in the order they’re given, so we need to make sure this is in the right place. Otherwise the code in our file may be overriden by code in Bootstrap files. We just told our template where our CSS file is located.

Your file should now look like this:

 html> html> head> title>Django Girls blog title> link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3" crossorigin="anonymous"> link rel="stylesheet" href=""> head> body> header> h1>a href="/">Django Girls Blog a> h1> header> article> time>published: > time> h2>a href="">> a> h2> p>> p> article> body> html> 

OK, save the file and refresh the site!

Nice work! Maybe we would also like to give our website a little air and increase the margin on the left side? Let’s try this!

Add that to your CSS, save the file and see how it works!

Maybe we can customize the font in our header? Paste this into your in blog/templates/blog/post_list.html file:

link href="//fonts.googleapis.com/css?family=Lobster&subset=latin,latin-ext" rel="stylesheet" type="text/css"> 

As before, check the order and place before the link to blog/static/css/blog.css . This line will import a font called Lobster from Google Fonts (https://www.google.com/fonts).

Find the h1 a declaration block (the code between braces < and >) in the CSS file blog/static/css/blog.css . Now add the line font-family: ‘Lobster’; between the braces, and refresh the page:

h1 a, h2 a < color: #C25100; font-family: 'Lobster'; > 

As mentioned above, CSS has a concept of classes. These allow you to name a part of the HTML code and apply styles only to this part, without affecting other parts. This can be super helpful! Maybe you have two divs that are doing something different (like your header and your post). A class can help you make them look different.

Go ahead and name some parts of the HTML code. Replace the header that contains your header with the following:

header class="page-header"> div class="container"> h1>a href="/">Django Girls Blog a> h1> div> header> 

And now add a class post to your article containing a blog post.

article class="post"> time>published: > time> h2>a href="">> a> h2> p>> p> article> 

We will now add declaration blocks to different selectors. Selectors starting with . relate to classes. There are many great tutorials and explanations about CSS on the Web that can help you understand the following code. For now, copy and paste it into your blog/static/css/blog.css file:

.page-header < background-color: #C25100; margin-top: 0; margin-bottom: 40px; padding: 20px 20px 20px 40px; > .page-header h1, .page-header h1 a, .page-header h1 a:visited, .page-header h1 a:active < color: #ffffff; font-size: 36pt; text-decoration: none; > h1, h2, h3, h4 < font-family: 'Lobster', cursive; > .date < color: #828282; > .save < float: right; > .post-form textarea, .post-form input < width: 100%; > .top-menu, .top-menu:hover, .top-menu:visited < color: #ffffff; float: right; font-size: 26pt; margin-right: 20px; > .post < margin-bottom: 70px; > .post h2 a, .post h2 a:visited < color: #000000; > .post > .date, .post > .actions < float: right; > .btn-secondary, .btn-secondary:visited < color: #C25100; background: none; border-color: #C25100; > .btn-secondary:hover < color: #FFFFFF; background-color: #C25100; > 

Then surround the HTML code which displays the posts with declarations of classes. Replace this:

 article class="post"> time>published: > time> h2>a href="">> a> h2> p>> p> article> 

in the blog/templates/blog/post_list.html with this:

main class="container"> div class="row"> div class="col"> article class="post"> time class="date"> > time> h2>a href="">> a> h2> p>> p> article> div> div> main> 

Save those files and refresh your website.

Woohoo! Looks awesome, right? Look at the code we just pasted to find the places where we added classes in the HTML and used them in the CSS. Where would you make the change if you wanted the date to be turquoise?

Don’t be afraid to tinker with this CSS a little bit and try to change some things. Playing with the CSS can help you understand what the different things are doing. If you break something, don’t worry – you can always undo it!

We really recommend taking the free online courses «Basic HTML & HTML5» and «Basic CSS» on freeCodeCamp. They can help you learn all about making your websites prettier with HTML and CSS.

Ready for the next chapter?! 🙂

Add CSS File to the Project

If you have followed the steps in the entire Django tutorial, you will have a my_tennis_club project on your computer, with 5 members:

We want to add a stylesheet to this project, and put it in the mystaticfiles folder:

The name of the CSS file is your choice, we call it mystyles.css in this project.

Open the CSS file and insert the following:

Modify the Master Template

Now you have a css file, the next step will be to include this file in the master template:

Open the master template file and add the following:

Check Settings

Make sure your settings.py file contains a STATICFILES_DIRS list with a reference to the mystaticfiles folder on the root directory, and that you have specified a STATICFILES_ROOT folder:

. . STATIC_ROOT = BASE_DIR / 'productionfiles' STATIC_URL = 'static/' #Add this in your settings.py file: STATICFILES_DIRS = [ BASE_DIR / 'mystaticfiles' ] . .

Collect Static Files

Every time you make a change in a static file, you must run the collectstatic command to make the changes take effect:

If you have executed the command earlier in the project, Django will prompt you with a question:

You have requested to collect static files at the destination
location as specified in your settings:

This will overwrite existing files!
Are you sure you want to do this?

Type ‘yes’ to continue, or ‘no’ to cancel:

Type ‘yes’. This will update any changes done in the static files, and give you this result:

1 static file copied to ‘C:\Users\Your Name\minverden\my_tennis_club\productionfiles’, 132 unmodified.

Now, if you run the project:

If you have followed all the steps on you own computer, you can see the result in your own browser:

In the browser window, type 127.0.0.1:8000/members/ in the address bar.

Spice up the Style!

In the example above we showed you how to include a stylesheet to your project.

We ended up with a purple web page, but CSS can do more than just change the background color.

We want to do more with the styles, and end up with a result like this:

First, replace the content of the mystyles.css file with this:

@import url('https://fonts.googleapis.com/css2?family=Source+Sans+Pro:wght@400;600&display=swap'); body < margin:0; font: 600 18px 'Source Sans Pro', sans-serif; letter-spacing: 0.64px; color: #585d74; >.topnav < background-color:#375BDC; color:#ffffff; padding:10px; >.topnav a:link, .topnav a:visited < text-decoration: none; color: #ffffff; >.topnav a:hover, .topnav a:active < text-decoration: underline; >.mycard < background-color: #f1f1f1; background-image: linear-gradient(to bottom, #375BDC, #4D70EF); background-size: 100% 120px; background-repeat: no-repeat; margin: 40px auto; width: 350px; border-radius: 5px; box-shadow: 0 5px 7px -1px rgba(51, 51, 51, 0.23); padding: 20px; >.mycard h1 < text-align: center; color:#ffffff; margin:20px 0 60px 0; >ul < list-style-type: none; padding: 0; margin: 0; >li < background-color: #ffffff; background-image: linear-gradient(to right, #375BDC, #4D70EF); background-size: 50px 60px; background-repeat: no-repeat; cursor: pointer; transition: transform .25s; border-radius: 5px; box-shadow: 0 5px 7px -1px rgba(51, 51, 51, 0.23); padding: 15px; padding-left: 70px; margin-top: 5px; >li:hover < transform: scale(1.1); >a:link, a:visited < color: #375BDC; >.main, .main h1

Modify Templates

You also have to make some changes to the templates:

Master

We want all pages to have the same top navigation, therefor we insert the top navigation into master.html :

Members

In all_members.html we want to make som changes in the HTML code.

The members are put in a div element, and the links become list items with onclick attributes.

We also want to remove the navigation, because that is now a part of the master template.

Details

In details.html we will put the member details in a div element, and remove the link back to members, because that is now a part of the navigation in the master template.

  Details about > >   
> >
 
Phone >
 
Member since: >
 
 

Main

In the main.html template, we will put some of the HTML code into a div element:

  My Tennis Club   
My Tennis Club
 
Members
 
Check out all our members
 
 

Collect Static Files

Since we did some changes in the static mystyles.css file, we have to run the collectstatic command to make the changes take effect:

Now, if you run the project:

You can see what the result should look like:

Or, if you have followed all the steps on you own computer, you can see the result in your own browser:

In the browser window, type 127.0.0.1:8000/members/ in the address bar.
