I'm having trouble with the layout in tablet and mobile views on my portfolio and elements aren't displaying properly

I'm hoping someone can help direct me with troubleshooting for my portfolio page. I'm currently having issues with a few things and I'm not sure why or how to deal with them. Whenever I try to view them in tablet/mobile views on the deployed link the layout is completely different than when I run a live server with npm start.
The first issue about section in mobile and tablet views displays each paragraph in columns and the black background doesn't cover all of the text or the image.
The second issue is the contact page doesn't display the links on mobile even though the text color is set to black and the contact header doesn't show up on the page.
It was made in React. Below will be the deployed link and link to the github.

I would really appreciate any help or guidance on sorting this out.
Thank you.
first piece of advice is that you have used TOO MUCH CSS, please use only what you really need. You don't need every css property to use on every element.
Your text/paragraphs are showing in column as their parent's display style is set first as inline and then flex. Either don't use it or write display: block

User Customizing Bing Map Infobox Description

I am currently developing an app using bing map v8 web control in react.js. I intend to add an input box in the info box so that users can enter their own description for the infobox. Just wondering is it possible to do it? If yes, can someone give me some hint on how to do it, and if not, is there other ways that I could let the users enter their own title for the pushpin?
I am new to Bing Map api and any help would be appreciated. Thanks in advance!
Not at this time. For some reason textboxs in the infobox can't get focused. I'll have the dev team look into this to see if there is a way around this.
Update (8/26/2016): The team has now added support for HTML in descriptions. Textboxes work in infoboxes too. This is currently available in the experimental branch of V8 and will be in the main release branch in a couple of weeks.

Use response CSS.
Twitter Bootstrap is great for this sort of thing. Divshot is a good tool for constructing user interfaces with Twitter Bootstrap.

Wordpress mobile integration?

I have an existing website that works with my custom theme. Unfortunately, it does not appear too well when I access it from my smart phone.
Can someone suggest a good plugin that will help with the user experience from a smart phone?
