# Blog Setup Day2

Set up my personal website using Jekyll

## Image and Math Support

One can easily import image in Markdown using ![image name](image path), another way of doing this is to use html syntax:

<div align="center"><img src="pic/image.png" alt="Image" style="zoom:%;" /></div>


In this way you can change the position and size of the image. From official guide, it’s recommanded to store all the images in asssets/images/, and also name the image like your post:YY-MM-DD-title.jpg.(html style of image is not originally supported in jekyll, so you might need some trick to set the right path for image)

To add math support the most common choice is mathjax. Just add these lines to the default.html layout before <head>:

<script type="text/x-mathjax-config">
MathJax.Hub.Config({
tex2jax: {inlineMath: [['$','$'], ['\$','\$']]}
});
</script>
<script type="text/javascript" async
src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.7/MathJax.js?config=TeX-MML-AM_CHTML">


The config here means you can use $...$ or \$...\$ for inline math because $...$ is not naturally support by mathjax.

## Custom Page Style

To change some of the default style like fonts, colors, margins one needs to modify some of the settings in layout and css. For me, I don’t like the footer to show up in every page, so I go to _includes/footer.html and comment everything in it, then the footer disappear. I also don’t like the title links have grey color, so I go to _sass/minimal-mistakes/_variables.scss to change the link-color in it. Here I won’t explain every configuration’s position to you, but show how I find them.

Basically every style configuration start from _layouts, every layout file might include components in _includes, the file in _includes tells what to show in every components, and the style of the components are in _sass. If you want to change someting, first you can use the consoler of your web browser (F12 for chrome and firefox) to find the name of the component you want to modify, then search through files in those folders using grep -R to locate the variables you want. One thing to notice is that most colors and fonts are defined in _sass/minimal-mistakes/_variables.scss.

## Drafts

Jekyll provide draft function to write post. Put the draft post in _drafts, then use bundle exec jekyll serve --draft, the posts in _drafts will be shown using the day time you run the command.
