New Pelican Theme

Posted on with tags: web development / pelican

This site has been online for more than one year. It is time to revise the pelican theme to present a new look. I spend a few hours revising the code, and now it is easier for myself to publish or revise articles.

The Bootstrap theme css file is now compiled on my computer. It is not too difficult to compile Bootstrap scss to css. This 17 minute long youtube video explains it very well.

Bootstrap 4 Theme Customization with Sass

I install Node version of Sass and Minify in Linux Mint with these commands. The Minify tool removes extra blanks and line breaks in the css, and it also works for js and html files.

$sudo npm install -g sass
$sudo npm install -g minify

#compile sass to css
$sass main.scss main.css
$minify main.css > main.min.css

The main.scss for the new theme has those contents.

$font-size-base: 1.1rem;
$h5-font-size: $font-size-base * 1.0;
$h4-font-size: $font-size-base * 1.1;
$h3-font-size: $font-size-base * 1.4;
$h2-font-size: $font-size-base * 1.6;
$h1-font-size: $font-size-base * 1.8;

$paragraph-margin-bottom: 1.2rem;
$headings-margin-bottom:  1.0rem;

$body-color: #111;
$headings-color: #333;
$link-color: #0017c7;
$code-color: #15228a;
$code-font-size: 88%;

$print-page-size: letter;

@import "node_modules/bootstrap/scss/bootstrap";

The light blue color of the navbar is set in the base.html file, which is copied from Bootstrap documentation.

<nav class="navbar navbar-expand-md navbar-light" style="background-color: #e3f2fd;">

The pelicanconf.py file also has a few changes. I remove default index.html page and change the previous about page to new homepage. The Python Typogrify package makes “double quotes” and other html elements look better.

# DEFAULT_PAGINATION = 3
INDEX_SAVE_AS = ''
SUMMARY_MAX_LENGTH = 30

# link to this file in base.html
# work computer blocks archives.html web page
ARCHIVES_SAVE_AS = 'articlelist.html'
TYPOGRIFY = True

The tasks.py file created by the pelican-quickstart command has a livereload task, which requires installing a Python package with the same name livereload. The live reload function is really nice. This is something you do not think you need before trying it, but after trying it you fall love with it. The default setting only watches for markdown and RST file types, you can add html to the list of files to watch.

I also change the github repo to SSH connection instead of HTTPS connection and add a public SSH key to the github account, so I do not need to type password when I update the github repo. This stackoverflow Q/A shows how to do it.
