New blog series - all roads lead to

Entry blog post about new series

Posted on Sun 19 March 2017

All of us know this saying - all roads lead to Rome. After taking with one of my coworkers about that all roads lead somewhere I decided to write small application that do exactly this thing - leading to somewhere

What this application will be about

What if I can make small front-end application to just write the name of city or place where all roads lead. Then the user selects two points in the map and every route between these two points is going through firstly selected point.

Entry screen implementation in HTML

As I want to use in this application some Google Map API I decided also to use Google Material Design Lite. It is the easy way to start with a good looking website without having to write all CSS by yourself.

At the beginning I created a header using mdl components:

<div class="mdl-layout mdl-js-layout mdl-layout--fixed-header">
    <header class="mdl-layout__header">
      <div class="mdl-layout__header-row">
        <div class="mdl-layout-spacer"></div>
        <span class="mdl-layout-title">All roads lead to ...</span>
        <div class="mdl-layout-spacer"></div>

Thanks to that I have this header right away:

My application header

I decided that user first has to type the name of city/place so I created a form:

<main class="mdl-layout__content">
  <div class="mdl-grid form-max-width">
    <div class="mdl-cell--12-col mdl-card mdl-shadow--4dp question-form">
      <div class="mdl-card__title">
        <h2 class="mdl-card__title-text">Select to which place all roads lead</h2>
      <div class="mdl-card__supporting-text">
        Click in search icon then type the name of place or city that you want to
        be your point. To this point all roads will lead.
        After you finish typing just hit enter.
      <div class="mdl-card__actions mdl-card--border">
        <form action="#">
          <div class="mdl-textfield mdl-js-textfield mdl-textfield--expandable">
            <label class="mdl-button mdl-js-button mdl-button--icon" for="place">
              <i class="material-icons">search</i>
            <div class="mdl-textfield__expandable-holder mdl-cell--12-col">
              <input class="mdl-textfield__input" type="text" id="place">
              <label class="mdl-textfield__label" for="place">Type place...</label>

What is interesting here besides normal stuff from material design? I've added two CSS classes: form-max-width and question-form with these CSS properties:

.form-max-width {
  width: 512px;

.question-form {
  margin-top: calc(100% / 2);

Which renders itself as follows:

Roads application search form

What I learned and what to do next?

This blog post was only the beginning and some warm-up before using JavaScript but I learned some useful information about having the ability to use calc in CSS or that using CSS frameworks can really speed up site creation process.

In next blog posts, I want to use Google Maps API to help me search for points and display map.

Take care and see you next week - don't forget to comment.
